The rollers are thin and long relative to their diameters. This kind of roller is called needle roller. Although it has a small section, the bearing still has a high load bearing capacity, so it is especially suitable for occasions with limited radial space.The contour surface of the needle roller shrinks slightly near the end face. Destructive edge stress can be avoided by correcting linear contact between needle and raceway.In the process of needle roller bearing technology, the production process of bearing involves blank forming (the bearing in the early stage needs to be well designed) → deburring (the bearing products are improving, and the precision of the bearing has been improved) → heat treatment (the heat treatment work needs to pay attention to the bearing technology) → coarse, fine Final grinding rolling surface (bearing, bearing products' meticulous in this respect and other characteristics need to be particularly important to the performance of bearing products) → superfinishing rolling surface or sawdust polishing (bearing products have received more support and comprehensive improvement after early processing)Needle Roller and Cage AssembliesShaftBearing No.Boundary Dimensions(mm)Basic Load Rating(N)Limiting SpeedFwEwBcCrCorOil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
