Your questions, our answers

What are the dimensions of a 6202 bearing?
The 6202 bearing has an internal diameter of 15 mm, an external diameter of 35 mm and a width of 11 mm.

How do I remove a 6202 bearing?
To extract a 6202 bearing, you can use a bearing extractor. Make sure the extractor is correctly positioned on the bearing's inner ring to avoid damaging surrounding components. Applying heat may also help to expand the metal and facilitate extraction.

How do I insert a 6202 bearing?
Care should be taken when inserting a 6202 bearing. Use a mounting tool or press to insert the bearing, applying even pressure to the outer ring. Make sure the bearing is correctly aligned to avoid damage during insertion.

How do I lubricate a 6202 bearing?
If you have an open 6202 bearing, apply lithium- or polyurea-based grease directly to the balls. For 2RS or ZZ bearings, regularly check the condition of the seals and replace them if necessary. If the seals are intact, these bearings are usually pre-lubricated.

How to choose a 6202 bearing
Choosing a 6202 bearing depends on the application. Take into account load, speed, environment (presence of dust, humidity), and possible maintenance. 2RS bearings are preferred for exposed environments, while ZZ or open bearings are used for high-speed applications.
