Product Description

Forklift Combined Track Roller Bearing 

The Combined Roller Bearing is composed of two main rollers, a side roller and a shaft head, which are installed in two different directions to reduce space and reduce manufacturing costs. The radial and axial direction bearing capacity is relatively large, and the accessories are highly replaceable. The adjustable combined roller bearing can adjust the position of the mandrel by adjusting the eccentric outer hexagon or the eccentric valve to achieve the purpose of adjusting the axial dimension of the side roller.

Specification

Applications

Composite roller bearings are mainly used in: forklifts, stackers, metallurgical industry, container front forks, cranes and other large lifting equipment and material lifting equipment.

combined bearings have been designed to meet the technical requirements of fork lift mast manufacturers but are also suitable for any other equipment where a linear motion is required.
combined bearings provide the best resolution of the external load into its components: 
the radial load acts on the main radial bearing and the axial load acts on the side guide rolle
