The product is comprised of needle or cylindrical rollers, a cage that guides and retains the rollers, and a disk shaped bearing ring, and is capable of holding an axial load in one direction. The mounting surface can be used as raceway surface when the mounting surface are beat-treated and finished. As a result, the bearing can be supplied without bearing ring raceways.

• Space Saving Design: Best-suited to save space because of its small section height and large load capacity
• Bearing Types: Current available bearing ring types are AS, WS, GS, and ZS. The AS type consists of a thin steel disk having undergone surface-hardening, while the WS, GS and ZS types are machined.
