is of sealed structure and filled with grease to provide long-term effective lubrication. Users can avoid lubrication. For bad service conditions, a channel for supplementing grease can be designed to improve the service life of the bearing. Improper method can also cause heating of roller bearing. Through moistening
Sliding can reduce the wear of parts in motion, ensure the accuracy of press and reduce energy consumption. Lubrication is divided into thin oil lubrication and thick oil lubrication.
Composition of combined roller bearing
1) Main roller
The main roller is the main bearing body of a set of composite rollers, which mainly bears the vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full loaded roller bearing, it can also be used alone as a one-way bearing.
2) Side roller
The side roller is the second bearing body of a set of composite rollers, which mainly bears the load in the horizontal direction, and also has strong impact resistance, wear resistance and corrosion resistance. The side roller is designed with full needle roller without inner ring, and a mandrel is used to replace the inner ring and the shaft head.
3) Shaft head
The shaft head is used as the connection part between the composite roller and the machine and equipment. Generally, the shaft head is designed as a chamfer for convenient installation. The shaft head can be directly welded to the equipment, or the shaft head can be welded to the connecting plate with round hole, and then the connecting plate and the equipment can be assembled.
4) Cover plate
The cover plate is an important part to fix the side roller installed inside the shaft head and the main roller outside the shaft head at the tail of the shaft head with nuts and thread glue.
