Product Description

Upper friction self-aligning roller with bracket:
I. Structural characteristics
 

1. Unique design: Composed of idlers, brackets, friction wheels and other components. The friction wheel contacts the conveyor belt and realizes the adjustment of the idler angle through friction.
2. Strong adjustability: It can automatically adjust the angle of the idler according to the running condition of the conveyor belt to maintain the stable operation of the conveyor belt.

II. Performance characteristics
 

1. Automatic centering function: When the conveyor belt deviates, the friction wheel will automatically adjust the angle of the idler under the action of friction to make the conveyor belt return to the center position, effectively preventing the conveyor belt from deviating.
2. Reduce wear: By adjusting the idler angle in time, the friction between the conveyor belt and the idler is reduced, and the wear of the conveyor belt and the idler is reduced, prolonging the service life of the equipment.
3. Stable operation: Ensure that the conveyor belt remains stable during operation, reducing material spillage and equipment vibration, and improving conveying efficiency and safety.
4. Strong adaptability: It can adapt to different belt widths, different conveying speeds and different material conveying requirements.

III. Characteristics of application scope
 

1. Widely used in various belt conveyor systems, especially suitable for long-distance and large-capacity conveying occasions.
2. For occasions with complex terrain and where the conveyor belt is prone to deviation, the friction upper-aligning idler set has significant advantages.

IV. Maintenance characteristics
 

1. Simple maintenance: The structure is relatively simple. Daily maintenance mainly includes checking the wear of the friction wheel and whether the idler rotates flexibly. The maintenance workload is small.
2. High reliability: Due to its automatic centering function and stable performance, the probability of equipment failure is reduced and the reliability of the system is improved.

 

1. Roller/idler introduction:

Our company specializes in R&D, developing and manufacturing of belt conveyors as well as various types of idlers/rollers, pulleys and roller brackets.
Rollers/idlers are important components of belt conveyors. Their function is to effectively support the conveyor belt and the materials carried on the conveyor belt, ensuring the normal operation of the conveyor. The diameters of idlers have domestic standards and foreign standards.
Domestic standards:Φ63,Φ76,Φ89,Φ108,Φ133,Φ159,Φ194,Φ219;
Foreign standards: Φ 89,Φ102,Φ114,Φ 127,Φ 139,Φ152,Φ 165,Φ 178 and other specifications.
