needle roller bearing
Needle-cage assembly, drawn cup needle roller bearing, light and mid-sized needle roller bearing, thrust needle roller bearing are suitable for the occasion of small space and high load capacity and widely used for gear driving system, turning system of automobile and engineering machinery as well as motor connecting rod of a motorcycle.
S1032/Y1032/R1032: They're double row needle roller bearing fistly developed by our facility in China. Every two needles as a unit, separated with cage assembly which can reduce the friction of neighbouring needles, and at the same time it can arrange more needles in the ring which makes a better load ability(15% raised). Now this technology has applied for national patent. Attached please find the drawing and picture.
At the same time, G2-grade raised degree super-precision needle is used, with low noise and better rotation performance.
This series overcomes the shortcomings of the same kind of products, and is a kind of product with low friction and larger load ability. It can be applied in various engineering machineries, high pressure oil pump, obviously leading of its kind. The quality is equal to world branded bearings, but valued prices.
