Roller

     The elastic roller refers to the rotating body on the cylindrical roller bearing. It is the spherical roller with the cylindrical roller bearing. The roller bearing is thin and long like a needle. This kind of roller bearing has high load bearing capacity and compact axial structure.

The cylindrical roller bearing is equipped with thin and long roller bearing (the length of roller bearing is 3-10 times of the diameter, and the diameter is generally not more than 5mm), so the axial structure is compact, and its nominal diameter specification and load working capacity are the same as other kinds of rolling bearings, the diameter is small, which is very suitable for the bearing plate results with limited axial installation specifications. According to different application places, rolling bearing or needle roller and cage parts without inner hole can be used. At this time, the surface of motor shaft and shell hole matching with rolling bearing shall be the inner and outer turning surface of rolling bearing immediately. To ensure the load working capacity and operation characteristics are the same as those of rolling bearing with ferrule, the strength of the surface of swallow tail guide rail of shaft or shell hole shall be produced and processed precisely Degree and surface quality shall be similar to the dovetail guide rail of roller bearing ring. This kind of rolling bearing can only bear axial load.
