The centripetal needle roller and cage assembly is a complete bearing unit composed of cage and needle roller. It is mainly used for shafts and bearing housings that can be used as raceways, and has the ability to withstand high loads and high rigidity with the minimum radial structural space. Under the high-precision shaft and seat hole raceway, higher rotation accuracy can be obtained; The working clearance can be adjusted according to the needle roller, mounting shaft and seat hole. The installation is very convenient, and it is a very economical bearing used under harsh conditions.

It is mainly used for shafts and bearing housings that can be used as raceways, and has the ability to withstand high loads and high rigidity with the minimum radial structural space. Under the high-precision shaft and seat hole raceway, higher rotation accuracy can be obtained; The working clearance can be adjusted according to the needle roller, mounting shaft and seat hole. The installation is very convenient, and it is a very economical bearing used under harsh conditions.
This series of bearings are mainly used for transmission shafts and gear boxes of automobiles, motorcycles and construction machinery.
1. Type and structure
This product of our company can be divided into three types according to the materials used for the cage: car made, stamping and reinforced nylon. According to the structural form of the cage, it can also be divided into M type, K type and other structural forms (see figure). The materials and structural forms can be designed according to the user's requirements.
2. Product precision
The difference between needle diameters is 2 μ m. The accuracy class is G2 (international GB/T309).
The upper deviation of the nominal width Bc of the component is -0.20, and the lower deviation is -0.55.
Technical requirements can also be determined separately according to user requirements.
3. Materials
The needle roller is made of GCr15 bearing steel.
Cage materials can be high-quality low-carbon steel, low-alloy steel and reinforced nylon according to different application occasions and requirements.
The bearings we produce are mainly used for: automobile parts, motorcycle parts, textile machinery, packaging machinery, food machinery, other machinery, etc
