Composition of combined roller bearings

Composition of combined roller bearings
The bearing has a sealed structure and is filled with grease to provide long-term effective lubrication, and the user can avoid lubrication. For the use of harsh working conditions, a channel for replenishing grease can be designed to improve the service life of the bearing. Improper methods can also cause the roller bearing to heat up. Lubrication can reduce the wear of parts during movement, ensure the precision of the press, and reduce energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication and so on.
Composition of combined roller bearings
1) Main roller
The main roller is the most important carrier in a set of composite rollers, which mainly bears vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full complement roller bearing, it can also be used as a one-way bearing alone.
2) Side scroll wheel
The side roller is the second carrier in 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 a full-needle roller design without an inner ring, and a mandrel replaces the inner ring and the shaft head to carry it.
3) Shaft head
The shaft head is used as the part connecting the compound roller and the machine equipment. Usually the head of the shaft head is designed as a chamfer, which is convenient for installation. The shaft head can be directly welded to the equipment, or welded to the connection with a round hole. Then assemble the connecting board and equipment on the board.
4) Cover plate
The role of the cover plate is to fix the side rollers installed inside the shaft head and the main rollers outside the shaft head with nuts and thread glue at the tail of the shaft head.
