Thrust ball bearing 51420. Under GOST the same bearing is designated 8420.

C, C₀, m: CT data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 8420?

It is the same bearing under GOST 3189-89: 8420 corresponds to the ISO base 51420. Size 100 × 210 × 85 mm, a full equivalent of 51420.

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.
