ISB Angular contact ball bearings: 70, 72, 73 series
Quiet Running Performances
Single row angular contact ball bearings, also identified with the acronym ACBB (Angular Contact Ball Bearing), are units with very peculiar features and constitute the 70, 72, 73 series. Created to support combined radial and axial loads with high rigidity, they have a row of balls working on mutually offset races in the axial direction. This structure generates an angular ball contact with a determined angle over which the load acting on the bearing is transmitted. Precisely for this fundamental constructive structure, the races of the angular bearings are the subject of accurate geometry studies and their machining is particularly challenging.
For ISB the 70, 72, 73 series angular contact ball bearings range is a strength, precisely because of its excellent functional features.
With ISB angular contact ball bearings, it is possible to obtain extraordinary performance in terms of running silence and service life, for all applications and needs, relying on qualified technical support fundamental for the selection and assembly of these ball bearing units.

Industrial Gearbox Maintenance Checklist
While a gearbox repair service like that provided by YB Components can be very helpful, it is usually better to avoid working a gearbox into a state of disrepair in the first place. Here we run through a gearbox maintenance checklist so you can keep your industrial gearboxes running smoothly for as long as possible.
The first item on any gearbox maintenance list will be a basic visual inspection. You should carry out visual inspections of all your gearboxes regularly to spot early signs of oil leakage, either on the input or output shafts. Also inspect any paintwork as discolouration could be an indication of overheating which is going to lead to problems down the road, so to speak.
Cleaning your gearboxes regularly also needs to be on any checklist, as they are usually operating in environments featuring a lot of dust and dirt. Without a frequent cleaning schedule, contaminants can get into the geared motor unit and cause issues, plus allowing dust to settle will raise the heat levels and lead to overheating. You can monitor the gearbox’s heat levels with an infrared gun which will show you if there are any noticeable changes that may indicate a problem.
Always lubricate the relevant gearbox components with the right type of lubricant. The manufacturer should have set out specific lubrication instructions which you can find out about either directly from the manufacturer or from a specialist gearbox supplier like YB Components.
Listening closely to the gearbox in operation can reveal any issues with excessive vibrations. However, a vibration analysis tool can be very useful, especially in a noisy environment where listening to the sound of the gearbox isn’t a viable option. The main components to analyse for vibrations are the bearings and internal gears, as any sudden increases in the amount of vibration will most likely be due to an issue that needs resolving.
Backlash and Endplay
Use a dial indicator to check backlash as any increase in backlash strongly indicates that the gear teeth have suffered significant wear and tear. Also use the dial monitor to check up on the endplay, as any endplay increase indicates excessive wear and tear on either the bearing or housings.
You should also monitor the input and output shafts to see if they are lifting or moving in ways that are not normal. Damage to the bearings or the housing of the bearings will cause unusual movements during operation. Regular use of a dial indicator will keep you informed of all backlash increases and irregular shaft movements.
Some gearboxes may suffer excessive wear and tear due to the demands placed upon them changing over time. It is possible that gearboxes performing poorly for this reason can be revitalised by a gearbox repair service, but first you should check the gearbox ratings to make sure the gearbox is actually operating within the manufacturer’s original specifications and power input.

Inspection and remanufacture of large-sized bearings stored for long periods
Large-size bearings that have been stored for long periods or that have been moved around from location to location could have endured internal damage. As such, we recommend that the bearings are intricately assessed and remanufactured before fitting.
Remanufacturing of large-size bearings stored over lengthy periods
Remanufacturing of large-size bearings stored over long periods can be a complex process, as the bearings may have sustained damage due to rust, corrosion, or several other factors.
The B2K Remanufacturing Process
Units that have been stored for long periods or that have been moved around from location to location could have endured internal damage. As such, the B2K and SKF reman center intricately assess how long the units have been in storage along with the quality of the preservatives still applied.
Our reman program entails meticulous cleaning, inspecting, analysing, and recertifying of the ball and roller bearings, giving you peace of mind that your large-size bearings are in sound condition and ready to fit.
- The first step in remanufacturing such bearings is to thoroughly inspect them to determine the extent of any damage. This may involve using non-destructive testing methods such as ultrasonic testing or a magnetic particle inspection to check for cracks, surface defects, or other issues.
- If the bearing surfaces are found to be in poor condition, they may need to be cleaned and resurfaced to remove rust and corrosion. This may involve using a variety of techniques, such as shot blasting or bead blasting to remove surface contaminants.
- Once the bearings have been cleaned and resurfaced, they will need to be reassembled and lubricated. The lubrication process is important to ensure that the bearings operate smoothly and that they are protected from rust and corrosion.
- It may be also necessary to replace some of the internal parts of the bearing such as rings, balls, or rollers if they have been damaged or worn over time.
- After remanufacturing, it’s essential to test the bearing to assess its performance and confirm that it meets the required specifications.

These 10 Things In Your Home Have Bearings In Them…
Did you know these 10 things in your home have bearings in them?
- Microwave. Bearings are perfect for reducing friction on objects that rotate. Next time you’re watching a Hot Pocket heat up, know there’s a bearing in the mechanism that spins the plate under it.
- Swivel chairs and stools. Bearings under the seat let a chair swivel, whether it’s a barstool, a chair in your home office, or a highly optimised gaming chair. Casters on the bottom of furniture use bearings to roll smoothly too.
- Food processor. Bearings and spinning things go together like peanut butter and chocolate. There’s a bearing in the motor that spins a food processor’s blade!
- Drawers. Drawer slides often include bearings so you can easily pull the drawer open, even when it’s full of heavy items like pots and pans.
- Toys. If you have children, you’ve probably slipped on a toy car. The wheels in that car have tiny bearings inside. From high-tech drones to the humble yo-yo, many of your kids’ toys and gadgets have bearings inside.
- Exercise equipment. Treadmills, ellipticals, and stationary bikes all have bearings to reduce friction during your home workout…whenever you finally get around to it.
- DVD player. A DVD must spin quickly and steadily for the player to read it correctly. A small bearing inside the machine keeps everything stable so you can watch your favourite movie for the 20th time.
- Washer and dryer. You may have noticed a pattern among many of these items: rotation. An appliance with a spin cycle would be useless without bearings. And nobody likes dirty clothes.
- Vacuum cleaner. Bearings smooth the motion of a vacuum’s suction fan and floor brush. Perfect for picking up all those crumbs that wind up under the couch.
- Drill. DIY with confidence. Your power tools have bearings in them to handle the load, friction, and vibration they create during use.
Bearings usually hide far from your sight, but you’d notice if they were gone. The smooth rotation they provide is essential to keep appliances and furniture working correctly. If you’re not sitting above one right now, try to guess when you’ll use a bearing next. It might be sooner than you expected.

4 Advantages Of Electronic Pressure Switches
Pneumatic pressure switches are a form of control valve which have the primary function of monitoring the pressure within a system and providing an output once a set parameter is met. They play a critical role in ensuring pressure is kept within an acceptable range, also helping to maintain the efficient running of machinery and safeguarding it from suffering damage. Monitoring pressure has never been so important. While it is imperative that the right pressure is delivered to machinery to ensure optimum performance, delivering pressures higher than needed just costs money. With most modern sensors having IO-link capability, it’s never been easier to monitor a system’s status – helping you keep costs under control.
When a machine’s compressed air pressure starts to fluctuate from its normal pattern, it’s usually a good early warning sign that something is starting to fail, allowing for planned maintenance rather than a critical, and usually, expensive breakdown happening.
In an age where digital advancements are becoming a key part of manufacturing environments, many industries are moving towards more advanced components and plants are becoming increasingly electrified and digitised. This shift has also improved the amount of choice our customers have when it comes to pressure switches, with the rising popularity of electronic switches.
It’s important to note that selection must always be guided by a range of factors within the application including operating temperature, pressure type (e.g., positive/ negative) and range, as well as the chemical properties of the process fluid. However, I wanted to use this article to cover some of the main advantages that electronic pressure switches have over mechanical alternatives.
1. Easily Readable Display
Electronic pressure sensors such as the 54D Series from Norgren® usually have an integrated LCD/LED display in a prominent, forward-facing position. This makes taking readings at the machinery side, quick and easy for engineers. Current pressure within the system can, therefore, be obtained efficiently and without requiring the use of any additional instrumentation, with signals converted to readable output within the single unit. The display also makes it possible to program parameters locally, giving users the ability to tweak them as necessary while constantly having visibility on the difference that their actions are having on the devices’ settings.
2. Simple Operation
Electronic pressure switches are blessed with simple operation and functionality. With its small number of buttons (often two), and a display giving visual feedback of all changes, configuration is easily completed locally. A simple combination of button presses enables switch points to be adjusted, saving time and effort devoted to such tasks by engineers. Some mechanical switches have the adjustment screw hidden in difficult-to access places such as underneath the DIN plug connector, making electronic switches far superior in terms of ease of use. Sensors with IO-link capabilities, such as the Norgren® 54D, make parameters even more convenient to reprogram as this task can be done remotely.
3. Improved Reliability
Mechanical switches rely on actuation from pressure-sensing elements to operate the switch, and these elements are often the cause of failures within the instrument. In comparison, the lack of moving components in electronic pressure switches makes them more reliable and permits them a longer, trouble-free service life. Fewer small parts within the electronic switches makes them less susceptible to the negative effects of vibration. Contact wear-out is also less of a concern than with traditional, mechanical switches.
Long-term stability and reliability can be achieved with electronic pressure switches when used appropriately, saving your business time and money in carrying-out the maintenance activities required to keep your operations running effectively.
4. Higher Accuracy And Repeatability
Electronic pressure switches are able to handle thousands of repeated pressure cycles without issue. This ability is inherently due to the high levels of accuracy that they provide and their superior reliability, particularly in applications where vibration is a consideration. The set points are maintained throughout the sensors’ lifetime with any deviation from the parameters not the issue that it is with mechanical switches.
Typical electronic pressure switch accuracies are around ±0.5% of the full-scale (FS) value, while piston-operated mechanical switches often deliver around ±2.0%, giving users peace of mind when it comes to both the effective pressurisation of their pneumatic system and the reliability of readings taken from the instrument.
The many advantages of using electronic pressure switches doesn’t mean that their mechanical predecessors should immediately be replaced. While there are many benefits to utilising electronic switches, their mechanical counterparts remain a good solution for handling less complicated tasks. They are also broadly better suited to handling high voltages and amperages than electronic switches. Electro-mechanical pressure switches, such as the 18D series from Norgren® are also on the market and act as a ‘halfway house’ between the two extremes.
