Filtomatic is a new member of BearingNet, and among the various products they manufacture are products that will certainly be useful to you or your customers.
Brief presentation of the company:
– Founded in 1963, for over 60 years they have produced parts that are stamped, tempered, superficially treated and finally 100% selected
– Working in the automotive sector from the starting days, it perfectly “lives” defect-free parts requirement
– Among the various items and services provided, which you can easily find on their website, focusing your attention on the one known as “compensation ring” or “compression ring” or “compensation spring for ball bearings.”
So this is why Filtomatic is turning to you! Filtomatic is really sure that your customers need their rings!
A totally silent operation of the ball bearing can only be obtained in ideal installation conditions, which are not economically sustainable in series production, despite the best quality of the bearing itself.
In many working conditions, using only a rotating bearing is more than enough to obtain a good result, but to obtain perfection, it is necessary to combine the bearing with a compensation spring.
The main function of the compensation ring is to absorb and compensate for the variations in length of the components due to changes in temperature, since they’re worn out, or because of deformation.

More specifically, Filtomatic can list some of the main uses of a compensation ring working with a bearing:
1. Heat compensation: during operations, materials can expand or contract due to temperature variations. The compensation ring allows these variations to be accommodated, maintaining the alignment and correct work of the bearing.
2. Consumption reduction: A bearing that is poorly aligned or subjected to non-uniform tension can wear out more quickly. A compensation ring helps to keep the bearing in the optimal position, reducing consumption and extending the usage “life” of the component.
3. Vibration minimisation: The compensation ring can help reduce vibrations within the system, improving stability and reducing noise. This is especially important in high-speed applications or in noise-sensitive applications.
4. Increased structural stability: In applications where loads can vary, the compensation ring helps maintain the stability of the bearing and other mechanical parts, ensuring better operation and greater system reliability.
5. Ease of maintenance: In some applications, a compensation ring can simplify bearing maintenance, allowing easier replacement or faster adjustment when necessary.
In summary, the compensation ring improves the reliability and efficiency of the mechanical system in which it is used, helping to ensure optimum performance and a longer life of the involved components.
Filtomatic has been producing this ring for over 60 years and has contributed with it’s studies to the specification of the DIN 42013 norm, expanding its customisation to produce over 50 different types of compensation rings to meet every useful need for a given design requirement.
For each ring Filtomatic are able to provide the graph expressing the force as a function of the working height to which the ring is compressed, suggesting the height range at which the ring should not be allowed to work (areas identified by the blue background) and indicating the guaranteed upper and lower load limits (red lines).
