Idler roller
Idler roller
Idlers are critical components of belt conveyors, serving to support the conveyor belt and the conveyed material, reduce running resistance, maintain the belt’s sag within specified limits, and ensure smooth operation. An idler consists of a roller body, bearings, seals, and other parts, and is classified according to application into troughed, parallel, and self-aligning types. It is widely used in mining, port operations, power plants, and other industries.
Idler roller
Our company specializes in manufacturing idler rollers that feature exceptional wear resistance, an extremely low coefficient of friction, and minimal belt abrasion. They also boast excellent self-lubricating properties, eliminating the need for lubrication and ensuring reliable operation even under harsh conditions without seizing. Additionally, they are antistatic, flame-retardant, resistant to aging, and highly resistant to corrosion by acids, alkalis, and organic solvents. These rollers can withstand repeated impacts and vibrations, and are suitable for use in ambient temperatures ranging from -40°C to 90°C.
It boasts excellent mechanical properties, lightweight construction, easy installation, and zero maintenance; it also operates stably and has a long service life. Our factory produces a wider range of conveyor belt-related products to fully meet your needs.
