NKI55/25-TV INA Needle Roller Bearing 55x72x25 With Inner Ring

Needle roller bearings with machined rings made of bearing steel have a low sectional height and a high load carrying capacity. They can be used with or without an inner ring. Needle roller bearings without an inner ring will require the shaft to be hardened and ground.
