FAQ

What does the 5/8 designation mean?

The 5/8 designation indicates an imperial bore size of 5/8 inch, equivalent to 15.875 mm.

Why choose a C3 clearance bearing?

C3 clearance provides additional internal space, helping compensate for thermal expansion during high-speed or high-temperature operation.

Is the bearing suitable for agricultural machinery?

Yes. The bearing is frequently used in agricultural equipment, especially machinery manufactured to imperial shaft standards.

Does the bearing require lubrication before installation?

No. It is factory greased and ready for immediate installation.

Can this bearing handle axial loads?

Yes. In addition to radial loads, it can support moderate axial loads in both directions.
