Product Description

What this is
An RBC KP12A-FS464 — a sealed, self-contained precision ball bearing. It has a 0.750 in bore, a 1.6250 in outside diameter and a 0.4375 in inner ring width. The rings are through-hardened 52100 bearing steel, cadmium plated for corrosion resistance, and the bearing is a full-complement design with no cage, which is what lets a bearing this small carry the loads it does. Sealing is PTFE with CRES (corrosion-resistant steel) sealcaps.

FS464 — RBC’s factory suffix identifying the seal and plating package on this build: PTFE seals with CRES sealcaps over a cadmium-plated ring set.
