[NTN] Shell Type Needle Roller Bearing HMK3512 (HK, HMK/Open End/35mm/45mm/12mm, 1pc)

Forming the outer ring by precision drawing processing on thin steel sheets, hardening the raceway surface, and installing a needle-shaped roller and retainer With an outer ring, it has the lowest cross-sectional height, enabling compact design and cost savings Compact design is possible by directly using the shaft as the raceway without using inner rings The outer ring has a structure where the needle-shaped roller and retainer are not separated With appropriate interference fit in a rigid housing, snap rings for axial fixation are unnecessary
