Product Description

A basic component of needle roller bearing, in which needle rollers are assembled with retainer to prevent separation.
[Features]
·A shaft or housing can be used directly as a raceway without an inner race or outer race, realizing the compact and lightweight design.
·The retainer allows needle rollers to be guided more accurately than full complement rollers, enabling high-speed rotation.
·Rigidity and load capacity are large for the space.
[Application]
·Ideal for heavy duty, high speeds, automobile gearboxes, etc.
·Ideal for steel equipment, mining/construction machinery, and machine tools.
