Shell-Style Needle Roller Bearing

Shell-Style Needle Roller Bearing

· Bearing includes a needle roller and cage installed following formation of an outer ring from a thin steel plate via precision drawing and surface curing of the corresponding raceway. (For model numbers with "M" in the suffix symbol, curing is performed after installation).
· Allows for space and cost savings and has the lowest section height of any bearing which includes an outer ring.
· Generally, designs which use the axis as a raceway directly do not include an inner ring.
· Structured so that the outer ring needle roller and the retainer do not separate, and handling is simplified as the bearing is only press-fixed to a rigid housing and no stop ring for performing fixing in the axial direction is required.
