Engineered for compact light-duty industrial machinery, agricultural equipment, and precision conveyor assemblies, the CSB203 17mm set screw insert ball bearing combines precision 17mm x 40mm x 12mm dimensions with a narrow inner ring and reliable set screw locking. Designed for space-constrained shaft mounting under moderate radial loads, it serves as an exact direct replacement for Fafnir/FAG M-YA017RR / AY17-NPP, Peer/FYH FHS203-17MM / SB203-17MM, Asahi/NTN US203 / ASS203-17, and cross references BR203 / FHSR203.
