Product Description:
The 51220 NTN consists of a shaft ring, a housing ring, and a ball and cage assembly. The shaft ring is mounted on the shaft and rotates with it, while the housing ring has a slightly larger bore diameter to allow clearance around the shaft.

This bearing can be disassembled, allowing the components to be mounted separately. Care should be taken during assembly to avoid mixing up the shaft ring and housing ring. The housing ring has a flat seat, meaning this bearing cannot compensate for misalignment between the shaft and housing.
