ChinaProduct DescriptionNeedle roller bearing is a roller bearing
with cylindrical rollers. 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
