Different types of stainless steel needles and their functions

The pin shaft strength is equipped with a thin and long needle, so the axial structure is compact. When 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 result of the support plate whose axial installation specification is limited. Different kinds of cylindrical roller bearings can be used according to different application places.

At this time, the surface of the motor shaft and the surface of the housing hole matched with the rolling bearing shall be the inner and outer turning surface of the rolling bearing immediately. In order to ensure the load working capacity and operation characteristics are the same as that of the rolling bearing with ferrule, the surface strength, production and processing precision and surface quality of the shaft or housing hole dovetail guide rail shall be similar to that of the roller bearing ring.

The cotter pin can only bear the axial load. The essence of the supporting point is that it can bear the axial load. It can also be understood that it is used to fix the fixed shaft. It is to fix the fixed shaft so that it can only maintain rotation, and manipulate its radial and axial movement. For example, the bad effect of the motor without rolling bearing is that the root cannot work. Since the shaft will exercise in all directions, the motor only requires the shaft to rotate during operation.

There are many kinds of structure forms of cylindrical roller bearing. There are two types of cylindrical roller bearing on the outside of stamping die: hole breaking type and sealing type. There is no inner hole in the cylindrical roller bearing on the outside of pin size, and the needle immediately touches the surface of the shaft. Therefore, the production and processing precision and heat treatment technology of the shaft should be the same as that of the inner hole of rolling bearing. Suitable for high speed, light load, multi-purpose CNC lathe, automobile, motorcycle transmission or textile equipment. The cylindrical roller bearing of punching die ferrule without cage is suitable for shaking under heavy load because it is full of needles.

The common solid line ferrule cylindrical roller bearings are NB type and RNB type, which are mostly used in CNC lathe and automobile transmission. Its advantages are small axial cross section specification and large axial load. The basic type of solid line ferrule cylindrical roller bearing often has a cage, so the rotation speed is relatively high, which can be integrated into the provisions of CNC lathe and automobile transmission.

Application fields of roller cylindrical roller bearing: printing equipment, forage machinery, agricultural machinery, roller and conveyor for slide rail of numerical control machinery, etc. In fact, needle roller and cage components are cylindrical roller bearings without rings. Application fields: this kind of rolling bearings are mostly used for large and small ends of the crankshaft of transmission, motorcycle and automobile. Because of the high temperature in the cylinder, the rolling bearing should be resistant to heat.
