Frequently asked questions

Can I fit another brand instead of this bearing?

Without checking, only an exact equivalent: the size, seal, clearance and design match according to the brand’s catalogue. Positions with the same geometry differ in seal, clearance or design, and each one says so in the equivalents block. Load ratings differ between manufacturers, so for a heavily loaded unit compare C.
