needle roller manufacturers make cylindrical roller bearings with short cylinders, cones, etc. as rolling elements. There are mainly several structural types such as radial short cylindrical rollers, tapered rollers and thrust rollers.

This type of roller is mainly used in cylindrical roller bearings, and the roller assembly can also be used directly in machinery. These rollers are standardized in size and can be used as commodity rollers for design and user selection.

In fact, there is still a certain degree of professionalism in the processing process of our roller bearings: the process of cylindrical roller blank forming → deburring or annular belt → soft grinding of raceway surface → soft grinding of double-end surfaces → heat treatment → pre-coarse grinding of rolling surfaces → rough grinding of double-end surfaces → Rough grinding rolling surface → Final grinding double end surface → Fine and final grinding rolling surface → Ultra-finishing rolling surface → Cleaning and drying → Final inspection of appearance and size grouping → Oiled packaging.

After the whole process, there are many points that need to be paid attention to in each link. This is also a test of whether a custom bearing manufacturer has the strength to control every management detail.
