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.<\/p>\n

Drive Pulley (Transmission Drum)<\/strong>
Designed as the primary power-transfer component, with surface options that increase friction by 30%\u201350%<\/strong> (rubber lagging or ceramic surface) to eliminate belt slippage. Heavy-load durability is supported by a thickened drum wall (10\u201330 mm)<\/strong> and integrated shaft design for deformation and fatigue resistance. Hot-vulcanized rubber lagging delivers a wear-resistant layer with 5\u201310 years<\/strong> service life and supports 24\/7<\/strong> continuous operation.\u00a0<\/p>\n

Bend Pulley (Directional\/Reversing Drum)<\/strong>
Used to optimize belt path alignment and increase stability, helping reduce belt misalignment. Available with customizable diameters (200\u20132000 mm)<\/strong> and surface treatments such as zinc-plated or stainless steel<\/strong> for humid and corrosive environments. Lightweight construction options (e.g., hollow shaft or lightweight alloys) can reduce overall load and energy consumption.\u00a0<\/p>\n

Polia com borracha<\/strong>
Engineered for high traction and high wear scenarios, the rubber-lagged surface increases friction by 30%\u201350%<\/strong> versus bare steel pulleys to ensure efficient power transmission and prevent slippage. Hot vulcanization combined with high-hardness rubber provides a 5\u201310 year<\/strong> wear layer lifespan and withstands impact from sharp materials such as ore and coke. It can extend conveyor belt life by 30%\u201350%<\/strong>, enable 10-year maintenance-free<\/strong> operation in heavy-duty scenarios, and reduce comprehensive O&M costs by 60%<\/strong>.\u00a0<\/p>\n

Rolo de acionamento motorizado (MDR)<\/strong>
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\u2014especially where space is limited or environments are complex, including humidity, mud, and high dust<\/strong> conditions<\/p>\n

Our idler portfolio focuses on impact resistance, corrosion protection, wear reduction, and stable tracking\u2014helping improve conveyor efficiency and reduce unscheduled downtime across mining, metallurgy, ports, and other heavy-duty applications.<\/p>

Enrolador de impacto<\/strong>
Built for high-impact transfer zones using a polymer polyurethane\/rubber composite ring array<\/strong> 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\u2014helping extend the service life of belts and drum components.<\/p>

Polia de a\u00e7o inoxid\u00e1vel<\/strong>
Manufactured from high-quality stainless steel formed by a spinning process for high strength and deformation resistance. Demonstrated 5\u20138\u00d7 longer service life<\/strong> versus conventional rollers and resists corrosion from acids, alkalis, salts, and aggressive chemical media<\/strong>. Commonly used in underground mines, thermal power plants, and ports; also designed to operate reliably under iron removers by resisting strong magnetic field adsorption.<\/p>

Polia com retardador de cer\u00e2mica<\/strong>
Designed for extreme high temperature, strong corrosion, and high wear conditions. Fully sealed ends with plastic labyrinth seals<\/strong> 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\u20133\u00d7 longer<\/strong> than steel rollers and can reduce belt wear while helping prevent belt deviation\u2014lowering total conveyor cost and maintenance hours.<\/p>

Polia de UHMWPE<\/strong>
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\u00b0C to 90\u00b0C<\/strong>, and it is widely used in high-dust and highly corrosive conditions with strong cost-effectiveness.<\/p>

Self-Aligning Idler (Self-Aligning Bracket)<\/strong>
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.<\/p>
