💡 How do rubber sealed bearings handle high RPM applications?
Rubber-sealed bearings like the R20-2RS are great for sealing out dust, but performance depends on proper use:
-
Suitable for moderate to high speeds, check RPM ratings
-
Ideal in environments with potential contaminants
-
Avoid over-lubrication, which can cause heat buildup
-
Replace seals if they show signs of wear or cracking
