FAQ

What is the advantage of the 6805 thin section bearing?

Its narrow 7 mm width allows installation in compact equipment while maintaining excellent rotational performance and reliable load capacity.

What does the 2RS designation mean?

2RS indicates rubber contact seals on both sides of the bearing that retain lubricant and protect against dust and moisture.

Why is C3 internal clearance recommended?

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

Is the bearing supplied pre-lubricated?

Yes. The bearing is factory greased and ready for installation.

Is this bearing suitable for OEM replacement?

Yes. The standardized dimensions of 25x37x7 mm make it suitable as a replacement for many OEM applications after verifying compatibility.
