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.

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