Designed for heavy-duty and continuous-operation conveyor systems, it delivers stable drive, excellent bending/fatigue resistance, and extended service life. The critical power core component of conveyors.
Core Product Values
- High-Strength Drum Structure with Fatigue & Impact ResistanceThe pulley features a thickened steel plate rolled drum, manufactured with automatic welding and full penetration welding technology. Boasting high structural strength, it resists deformation and cracking, suitable for:
- Heavy-load materials
- Long-distance conveying
- High-frequency start/stop cycles
- Harsh environments (dust, humidity, etc.)The entire pulley undergoes static or dynamic balancing treatment for smoother operation.
- High-Precision Bearing Housings & Welded Structure for Reliable OperationShaft ends at both sides of the pulley are made of high-strength 45# or 40Cr forgings, processed via CNC machining to ensure:
- High concentricity
- Strong load-bearing capacity
- Excellent torsion resistanceShaft ends are connected to the drum via gantry welding or submerged arc automatic welding, ensuring stable and reliable weld quality.
- Multiple Lagging Options for Enhanced Friction & LongevityDrive pulleys offer various lagging solutions based on working conditions:
- Flat Cold Vulcanized Lagging / Hot Vulcanized LaggingSuitable for general conveying systems, improving friction and preventing slippage.
- Chevron LaggingIdeal for wet/slippery conditions, enhancing friction coefficient.
- Ceramic LaggingDesigned for heavy-load, wet, and high-dust environments, providing superior grip, anti-slip performance, and wear resistance — service life 3–5 times longer than standard rubber.
- Comprehensive Pulley Types AvailableWe offer a complete range of pulleys:
- Drive Pulley
- Bend Pulley / Snub Pulley
- Tail Pulley
- Take-up Pulley
- Magnetic Pulley
- Specialized Pulleys for Rainproof & Corrosion-Resistant EnvironmentsMeets the structural requirements of various conveyors.
