Product description

The outer ring of roller bearing adopts full-scale cylindrical roller bearing with thick outer ring wall. The outer diameter of roller has cylindrical and arc. It can be designed according to the use situation to match with the roller surface. With this outer ring, the roller can roll directly on the raceway, and can bear heavy load and impact load.

The bearing is a sealed structure, filled with grease, providing long-term effective lubrication, and the user can avoid lubrication. For the channel with bad service condition, the passage of lubricating grease can be designed to improve the service life of bearing. Improper method can also cause the roller bearing to heat. Through lubrication, the wear of parts can be reduced, the accuracy of press can be guaranteed and energy consumption can be reduced. Lubrication is divided into thin oil lubrication, concentrated oil lubrication, etc.

Composition of combined roller bearing

Main roller

The main roller is the most important 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 full loaded roller bearing, it can also be used as one-way bearing alone.

Side roller

The side roller is the second bearing body of a set of composite rollers, which mainly bears horizontal load, 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 shaft head for connecting and bearing.

Shaft head

The shaft head is a part of the connection between the composite roller and the machine equipment. Usually, the head of the shaft head is designed as chamfering, which is convenient for installation. It can directly connect the shaft head to the equipment, or weld the shaft head on the connecting plate with round holes and then assemble the connecting plate and equipment.

Cover plate

The function of the cover plate is to fix the side roller installed inside the shaft head and the main roller outside the shaft head together with nuts and thread glue at the end of the shaft head.
