Why Maintenance Matters More Than You Think
Bearings don’t fail overnight. They fail gradually—from small maintenance gaps that accumulate over time. A little overgreasing here, a bit of misalignment there… and soon enough, you’re facing an unexpected production stop.
With these 5 practical maintenance hacks—and a few bonus tips—you can extend the life of your bearing units, prevent breakdowns, and reduce operational costs.
1. Use the Right Seal for Your Environment
Seals are the first line of defence against dirt, moisture, and contaminants. Choosing the wrong seal type can significantly reduce bearing lifespan.
Common Seal Types
- Triple Lip Seals: Excellent for environments with frequent washdowns or high humidity.
- Labyrinth Seals: Designed for high-speed applications, they minimise friction and heat buildup.
- Contact Seals: Good for general applications but less effective in aggressive conditions.
Pro tip: In food or pharmaceutical environments, always verify that your seal materials are compliant with hygienic standards.
2. Don’t Overgrease—Use the Right Grease
One of the most common maintenance mistakes is assuming “more grease = better.” Overgreasing creates internal pressure that can blow out seals and increase friction.
Grease Types for Specific Needs
- Food-grade grease: Required in food processing facilities.
- High-temperature grease: Best for kilns, dryers, or motors under heavy heat.
- EP (Extreme Pressure) grease: Perfect for applications with shock loads or high loads.
How Often Should You Lubricate?
A general rule: every 500 operating hours. However, factors like speed, load, and temperature affect this. Use vibration data or maintenance logs to define your ideal frequency.
Ivor Bearings tip: Many of our bearing units come pre-lubricated or include easy-access grease fittings to simplify maintenance routines.
3. Align It Right: The Invisible Failure Factor
Misalignment is a silent killer. It generates heat, vibrations, uneven wear, and leads to premature failure—yet it often goes unnoticed.
Common Misalignment Scenarios
- Long conveyor shafts with multiple support points (UCP, UCFL, UCFC).
- Shafts with multiple pulleys or rigid couplings.
- Motors and gearboxes that require precise installation.
How to Ensure Proper Alignment
- Use laser alignment tools for high-precision installations.
- Use feeler gauges or straightedges for simpler setups.
In tapered roller bearings or adapter-sleeve assemblies, poor alignment can also affect internal clearance—leading to overloading and heat damage.
4. Rotate Idle Equipment Monthly
Idle machines may seem harmless, but they’re vulnerable to a condition called false brinelling—micro-indentations caused by static vibration or lubricant migration.
How to Prevent It
- Manually rotate shafts once a month.
- If possible, briefly run idle motors under no load.
- Make sure lubrication covers the rolling elements consistently.
Common risk zones include seasonal machinery, backup production lines, and emergency-use equipment.
5. Add Vibration Monitoring = Early Detection
Installing basic vibration or thermal monitoring tools allows you to detect small issues before they become major problems.
Abnormal vibration usually signals:
- Misalignment
- Lubrication issues
- Cage or rolling element damage
Tools That Help
- Wireless accelerometers
- Infrared thermal cameras
- Predictive maintenance software
Did you know? Plants using vibration-based predictive maintenance reduce repair costs by up to 40% on critical machines.
