TECHNOLOGY
Core Capabilities
Out of the bearing family, needle roller bearings have the smallest cross-sectional area and volume. high loading capacity, ideal for applications where space and weight are limited. Mechanical efficiency is considerably enhanced from
reduced torque, inertia force, and lower friction for its characteristic small size and light weight.
The caged needle rollers, as loading components of line contact, is suitable in vibrated or harsh environment under high speed.
The grade of raw materials, cylindricity and roundness of the needle rollers are the key factors to say if they deliver high load capacity and smooth rotation that we expect a high-quality needle roller bearing has. Which is why NRB sources high cleanliness bearing steel (JIS SUJ-2/SAE 52100/DIN 100 Cr6) needle rollers made from professional Japanese manufacturers only.
NRB focuses on develop and manufacture of turn cage with high quality parallelism in consistency. Combining technology know-how of choosing controlled contours configuration and refinement of needle rollers that gives more uniform stress distribution and optimum bearing performance per application, the expertise customers can rely on.
