What is the difference between a drive pulley and a bend (tail) pulley?

A drive pulley transmits power to the conveyor belt, while a bend (tail) pulley mainly changes belt direction and supports stable routing at the tail or return path.

Which pulley option best prevents belt slippage?

For anti-slip traction, choose a drive pulley with rubber lagging or a ceramic surface. These options are designed to increase friction and reduce slippage in demanding conditions.

Can ceramic lagged idlers help reduce belt deviation and wear?

Yes. Ceramic lagged idlers are designed for high wear and harsh conditions and can help reduce belt wear and support more stable belt operation, which may help mitigate deviation in challenging applications.

Why choose UHMWPE idlers for harsh operating conditions?

UHMWPE idlers feature ultra-low friction and anti-adhesion properties, low noise, and wide temperature adaptability for long-term operation (commonly stated from -49°C to 90°C), making them suitable for dusty and corrosive environments.

Conveyor Pulleys and Idlers

Q: When should I choose a rubber-lagged pulley?

Rubber-lagged pulleys are recommended for heavy-duty, high-wear, and humid environments where higher traction and longer wear life are required. In heavy-duty scenarios, they are positioned to extend belt life and reduce overall maintenance costs.

Q: What idler is recommended for high-impact loading zones?

Impact idlers are designed for transfer/loading zones and typically use buffering ring structures to absorb shock, helping protect the belt and reduce damage from large or sharp materials.

Q: Which idler is best for corrosive or chemical environments?

Stainless steel idlers are commonly selected for corrosive conditions due to strong resistance to chemical media. Ceramic lagged idlers may also be used when both corrosion resistance and high wear performance are needed.

Q: How do self-aligning idlers improve conveyor stability?

Self-aligning idlers are designed to help correct belt misalignment during operation, reducing the risk of deviation, material leakage, and abnormal wear of conveyor components under load.

Built for heavy-duty conveying—high-traction pulleys and long-life idlers engineered for dust, moisture, corrosion, and continuous operation.

Conveyor Pulleys

Our pulley lineup covers the key power and routing components used in belt conveyors, with configuration options designed to improve traction, reduce slippage, and maintain stable belt travel in demanding environments.

Drive Pulley (Transmission Drum)
Designed as the primary power-transfer component, with surface options that increase friction by 30%–50% (rubber lagging or ceramic surface) to eliminate belt slippage. Heavy-load durability is supported by a thickened drum wall (10–30 mm) and integrated shaft design for deformation and fatigue resistance. Hot-vulcanized rubber lagging delivers a wear-resistant layer with 5–10 years service life and supports 24/7 continuous operation.

Bend Pulley (Directional/Reversing Drum)
Used to optimize belt path alignment and increase stability, helping reduce belt misalignment. Available with customizable diameters (200–2000 mm) and surface treatments such as zinc-plated or stainless steel for humid and corrosive environments. Lightweight construction options (e.g., hollow shaft or lightweight alloys) can reduce overall load and energy consumption.

Rubber-Lagged Pulley
Engineered for high traction and high wear scenarios, the rubber-lagged surface increases friction by 30%–50% versus bare steel pulleys to ensure efficient power transmission and prevent slippage. Hot vulcanization combined with high-hardness rubber provides a 5–10 year wear layer lifespan and withstands impact from sharp materials such as ore and coke. It can extend conveyor belt life by 30%–50%, enable 10-year maintenance-free operation in heavy-duty scenarios, and reduce comprehensive O&M costs by 60%.

Motorized Drive Roller (MDR)
A highly integrated unit combining motor and drum to reduce external transmission components, save footprint, and simplify installation. It is widely used in conveyors, sorting systems, logistics warehousing, and mining/port scenarios—especially where space is limited or environments are complex, including humidity, mud, and high dust conditions

Conveyor Idlers

Our idler portfolio focuses on impact resistance, corrosion protection, wear reduction, and stable tracking—helping improve conveyor efficiency and reduce unscheduled downtime across mining, metallurgy, ports, and other heavy-duty applications.

Impact Idler
Built for high-impact transfer zones using a polymer polyurethane/rubber composite ring array with an elastic buffer layer. The reinforced roller body and buffer design balance impact resistance and load-bearing strength, supporting heavy-duty conveying where large ore or metal shavings create strong impacts—helping extend the service life of belts and drum components.

Stainless Steel Idler
Manufactured from high-quality stainless steel formed by a spinning process for high strength and deformation resistance. Demonstrated 5–8× longer service life versus conventional rollers and resists corrosion from acids, alkalis, salts, and aggressive chemical media. Commonly used in underground mines, thermal power plants, and ports; also designed to operate reliably under iron removers by resisting strong magnetic field adsorption.

Ceramic Lagged Idler
Designed for extreme high temperature, strong corrosion, and high wear conditions. Fully sealed ends with plastic labyrinth seals prevent oil/grease leakage and enable long-term sealed operation. The ceramic surface forms an oxide film that does not adhere/react, helping material fall off naturally; service life is 2–3× longer than steel rollers and can reduce belt wear while helping prevent belt deviation—lowering total conveyor cost and maintenance hours.

UHMWPE Idler
Built around ultra-high molecular weight polyethylene for ultra-high wear resistance, ultra-low friction, and strong anti-adhesion. It runs with low noise and low rotational resistance, offers strong mechanical strength against repeated impacts/vibrations, and is lightweight for easier replacement and energy efficiency. Wide temperature adaptability supports long-term operation from -49°C to 90°C, and it is widely used in high-dust and highly corrosive conditions with strong cost-effectiveness.

Self-Aligning Idler (Self-Aligning Bracket)
A simple-structure solution with a significant self-aligning effect to prevent belt deviation, material leakage, and abnormal equipment wear. Reinforced materials and techniques support long-term stable operation under high-load conditions.
