Product description

The friction self-aligning roller set has a strong ability to prevent the conveyor belt from being damaged and deviating. It uses the friction resistance and the deflection mechanism of the friction wheel arc to prevent and correct the deflection of the conveyor belt and achieve the effect of centering. The friction self-aligning roller set is an important part of the belt conveyor. There are many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and bears more than 70% of the resistance, so the quality of the roller is particularly important. The function of the friction self-aligning roller group is to support the weight of the conveyor belt and the material, and the roller can run flexibly. Reducing the friction between the conveyor belt and the idler roller plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the idler roller is a small part in the belt conveyor, the structure is not complicated, but It is not easy to manufacture rollers.

The friction self-aligning roller set adopts standard design and manufacturing technology to improve the design and manufacture of rollers to a high level. The rollers produced have low rotation resistance, long life, small maintenance workload and high load-bearing capacity.

The steel pipe adopts idler high-frequency welded pipe, and the inside of the pipe is deburred, and the roundness is controlled within the tolerance range. The shaft is made of cold drawn steel processed to standard tolerances. The bearing seat is made of cold-rolled steel plate through multiple stamping processes. The roller shell and the bearing seat are welded together by an automatic welding manipulator to form a very integrated structure. The roller bearing adopts the well-known deep groove ball double-sealed bearing with large clearance, so that the roller has ideal static and dynamic balance, and its rotation resistance is better than the national standard. The roller seal is specially designed with the characteristics of comprehensive and domestic labyrinth seal, and it is filled with lithium-based ester resistant to high-speed, high-temperature and ultra-low temperature to prevent impurities, water, and air from corroding the interior of the roller.
