Product description

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

The bearing is a sealed structure, filled with grease, providing long-term effective lubrication, users can avoid lubrication. For the bad working conditions, we can design the channel to add grease to improve the service life of the bearing. Improper way can also cause roller bearing heating. Lubrication 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

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. As the main roller is full loaded roller bearing, it can also be used as one-way bearing.

Side roller

The side roller is the second bearing body of a set of composite rollers, which mainly bears the horizontal load, and also has strong impact resistance, wear resistance and corrosion resistance. The side roller is designed with full needle without inner ring, and a mandrel is used to replace the inner ring and connect with the shaft head to carry the load.

Shaft head

The shaft head is used as the connecting part between the compound roller and the machine equipment. Generally, the shaft head is designed with chamfering, which is convenient for installation. The shaft head can be directly welded on the equipment, or the shaft head can be welded on the connecting plate with round hole, and then the connecting plate and the equipment can be assembled.

Cover plate

The cover plate is an important part of fixing the side roller inside the shaft head and the main roller outside the shaft head at the end of the shaft head with nuts and screw glue.
