China Suppliers Factory Bend Pulley for Belt Conveyor System - High-Quality Reversing Drum Components
Function and Application
1
This component has two main functions:
①
By changing the direction angle by 180°, the trajectory of the conveyor belt can be altered, with 180° turning being commonly used at the rear of the conveyor.
②
Tighten the conveyor belt to increase its contact angle with the drive pulley, and the increase in angle can reach 30% – 50%, effectively preventing slipping.

Frequently Asked Questions
Q
What is the primary function of a bend pulley in a conveyor system?
A bend pulley serves two main functions: it changes the direction of the conveyor belt by up to 180°, and it tightens the belt to increase its contact angle with the drive pulley by 30%–50%, effectively preventing belt slippage.
Q
What sizes are available for the bend pulley?
The bend pulley is available in five standard diameter sizes: 220mm, 320mm, 400mm, 500mm, and 600mm, with corresponding shaft diameters of 40mm, 50mm, and 60mm. Custom sizes can also be produced upon request.
Q
What is the cylinder body length range for the bend pulley?
The standard cylinder body length ranges from 500mm to 1400mm. Customized lengths are also available to meet specific project requirements.
Q
What industries commonly use bend pulleys?
Bend pulleys are widely used in the mining industry (especially underground coal mine conveyor systems), port bulk cargo terminals for loading and unloading, and metallurgical plants for high-temperature material conveying lines.
Q
What is the dust-proof rating of the bearing housing seal?
The bearing housing features a sealed structure with a dust-proof protection level of IP54, making it suitable for harsh working environments such as mines and steel plants where dust and debris are prevalent.
Q
What is the allowable radial runout error for the bend pulley?
The technical standard requires the radial runout error to be no greater than 0.5mm per meter, ensuring stable and precise rotation performance during continuous conveyor operation.
