FAQ

What makes the 6902 bearing suitable for compact machinery?

Its thin section design with a 7 mm width allows installation where radial space is limited while maintaining excellent running performance.

What does the 2RS designation mean?

2RS indicates rubber contact seals on both sides of the bearing that retain lubricant and prevent contamination.

Why is C3 internal clearance important?

C3 clearance compensates for thermal expansion, interference fits and higher operating temperatures while maintaining smooth rotation.

Is the bearing supplied ready for installation?

Yes. The bearing is factory lubricated and sealed, requiring no additional lubrication before installation.

Can this bearing be used as an OEM replacement?

Yes. Its standardized ISO dimensions of 15x28x7 mm make it suitable as a replacement for many OEM applications after confirming compatibility.
