The composite roller bearing has a relatively large radial and axial load-bearing capacity, and the accessories are highly replaceable. In addition to the application fields shown above, it is also increasingly used in various mast lifting systems. Here are its components:

1. Shaft head

The installation method of the composite roller bearing is welding, the specific method is to weld the shaft head to a plate with a round hole, and then assemble it with the gantry;

2. Cover

Install the main side roller shaft heads together to form a whole.

3. Main roller

The main roller is the main load-bearing body in the composite roller bearing. It mainly bears the load in the vertical direction and requires strong wear resistance, corrosion resistance and impact resistance. At the same time, the main roller can also be used as a single-direction load bearing, because it itself is a roller bearing with a full roller structure;

4. Side roller

Side rollers are the secondary load-bearing body of composite roller bearings, which mainly bear horizontal loads and also require strong wear resistance, corrosion resistance and impact resistance. The side roller is essentially a roller bearing without an inner ring and full needle rollers. The inner part of the composite roller bearing is matched with the spindle and the shaft head;
