Impact Roller Idlers:
Impact rollers are used as carrying rollers instead of normal steel rollers at a loading point. On steel roller there are rubber rings assembled, side by side, to absorb the weight and impact of material falling onto the belt. At the same time impact rollers reduce the shock and vibration through the steel structure.

Rubber Disc Return Roller Idler
Disc Return Rollers are used where the material has the potential to collect on the surface of the rollers which could ultimately lead to premature failure. The Ring minimises material build up on the roller shell. To maximise longevity, routine cleaning should still be observed. Rings come in rubber as standard.

Product Features

• High-quality Materials: The materials for the roller skins of various idlers are strictly selected. High-quality special welded pipes are used, and strict tolerance requirements are set. This can ensure the roundness and straightness of the idlers and reduce the wear of the conveyor belt. The shaft materials are cold-drawn round steel, which has high strength and good toughness and can bear a large load. The bearing seats are stamped from high-quality steel plates, which are sturdy and durable and provide good support for the bearings.
• Good Sealing Performance: The sealing structure adopts a PDC-type three-way sealing device, which has excellent dust-proof and waterproof performance. It can effectively prevent dust, water vapor, etc. from entering the interior of the bearings, extend the service life of the bearings, and reduce the maintenance cost.
• Low-resistance Operation: After assembly, the rollers have good strength, small radial runout, and low rotational resistance. This helps to reduce the running resistance of the conveyor belt, minimize energy consumption, and improve the efficiency of the conveying system.
• Long Service Life: Due to the use of high-quality materials, advanced manufacturing processes, as well as good sealing and low-resistance designs, the return idlers of this company have a long service life. It can reduce the frequency of idler replacement and improve production efficiency.
• Product Functions
• The return idler is mainly used to support the unloaded section of the conveyor belt, enabling the conveyor belt to smoothly return to the driving device and form a complete cycle. It can help maintain the shape and position of the conveyor belt, prevent problems such as deviation and sagging of the conveyor belt during operation, and ensure the stable operation of the conveying system. In addition, some return idlers may also have a certain centering function, which can automatically adjust the position of the conveyor belt, further improving the reliability and stability of the conveying system.
