Do maintenance-free bearings really require no maintenance?

Do maintenance-free bearings really require no maintenance?

2025-04-28

Simply put, maintenance-free bearings are bearings with built-in dust covers or rubber seals. In mechanical operation, bearings play a role in reducing friction and supporting loads, and the advantage of maintenance-free bearings is that they are not easily contaminated by external impurities, so they are widely used in various mechanical equipment. So does this maintenance-free bearing need to be relubricated? The answer is simple: usually, no!


Maintenance-free bearings
01
One-time design Maintenance-free bearings are filled with enough high-quality grease when they leave the factory, and generally no additional grease is required within the design life range. This is equivalent to buying a peace of mind service, and you don’t need to worry about it at ordinary times.
Maintenance-free bearings
02
Strong sealing performance The seals of maintenance-free bearings have a strong protective effect, which can effectively prevent the entry of dust and moisture and extend the service life of the bearing. It is not only difficult to easily open the seals, but it may also destroy their original protective performance, which is not worth the loss.
Maintenance-free bearings
03
Effort-saving and worry-free Because there is no need to frequently check the lubrication status and add grease, a lot of maintenance and management time and cost are saved. Time is money in modern industrial production, and this advantage is particularly important.
