C series QD bushing pulley
C Heavy-duty pulleys use 1 to 12-groove QD inch bushings, and the QD metric bushing type provides inventory flexibility by changing the bushing diameter. The C-groove pulley can see our various C-belts for maximum flexibility and horsepower range. The pulley is balanced and precisely machined to reduce vibration. Any pulley manufacturer's most significant product selection ensures the best results and most economical drive design for a particular application. The company is the first company in the industry to provide powder coating p for pulleys, which is durable and can protect products from rust in high-humidity environments. If you need help, please contact us.

Advantages of V-Belt Pulleys:

  1. Efficient Power Transmission - V-shaped grooves maximize belt contact, reducing slippage and improving torque transfer.

  2. Shock Absorption - Cushions machinery from sudden load changes, protecting components.

  3. Cost-Effective - Affordable manufacturing and maintenance compared to chain or gear drives.

  4. Versatile Speed Control - Adjustable pulley sizes enable variable speed ratios.

  5. Quiet Operation - Generates less noise than metal chain drives.

  6. Easy Installation/Maintenance - Simple to mount, align, and replace with basic tools.

  7. Durable Materials - Cast iron, steel, or aluminum construction for long service life.

Applications of V-Belt Pulleys:

  1. Industrial Machinery - Conveyors, pumps, lathes, and compressors.

  2. Agricultural Equipment - Tractors, combines, and irrigation pumps.

  3. Automotive Systems - Alternators, water pumps, and superchargers.

  4. HVAC Systems - Blowers, fans, and air handling units.

  5. Home Appliances - Washing machines, dryers, and power tools.

  6. Mining/Construction - Crushers, elevators, and drilling rigs.

  7. Renewable Energy - Wind turbines and hydroelectric generators.
