Import Eu Standard V Belt Pulley : Spz, Spa, — Buy in wholesale FOB from Supplier in China

The EU standard V belt pulleys from Sichuan Mighty Machinery. Co.,Ltd. are manufactured to EN 14527 specifications for SPZ and SPA profiles, with groove counts up to 10 and bore diameters ranging from 10mm to 80mm. These pulleys are designed for taper bushing mounting, allowing for easy installation and axial adjustment without keyways. The material is gray cast iron GG25, with surface finishes either bare or coated with anti-rust oil as standard. Each unit is precision-machined to maintain concentricity within 0.05mm and dynamic balance per ISO 1940-1 G6.3.

Typical industry tolerances for SPZ pulleys include a groove width of 8.5mm ±0.1mm and a groove angle of 34°, while SPA pulleys have a groove width of 11mm ±0.1mm and the same angle. The pulleys are compatible with standard V-belts of corresponding profiles and are commonly used in industrial motors, agricultural machinery, and conveyor systems. Variants include solid hub designs for light-duty applications and split hubs for shafts where disassembly is impractical. Surface hardness typically exceeds 180 HB, ensuring durability under continuous belt tension.

These pulleys are sourced primarily by manufacturers of mechanical drives in Europe, Southeast Asia, and Latin America for replacement and OEM applications. Buyers commonly order in batches of 50 to 500 units, with packaging in individual cardboard boxes inside export cartons. Lead times for standard sizes range from 15 to 25 days after order confirmation. Incoterms offered include FOB Chengdu and CIF ports in Shanghai or Ningbo.
