Touch axis

The roller backstop 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 types of rolling bearings, with the minimum diameter, which is very suitable for the bearing plate results with limited axial installation specifications. According to different application places, roller locking without inner hole or roller needle and cage parts can be used. At this time, the surface of motor shaft and shell hole matched with rolling bearing can be used as the inner and outer turning surface of rolling bearing. 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 can 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.
