Descripción del producto

1. Double row needle roller bearing with entity ring of our company's is firstly developed in China. Every tow 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(*5% raise). Now this prpduct has applied for national patent. 2. At the same time, G*-geade raised degree super-precision needle is used, with low noise and better rotation performance. 3. This new product 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.
