SPC 4 Groove Taper Lock Pulley
SPC 4 Groove Pulley Specifications & Dimensions
As a leading China factory manufacturer and custom OEM supplier, PowerTrans manufactures precision-engineered SPC 4 groove pulley units for medium-duty power transmissions. We cast each pulley from fine-grain gray cast iron in strict compliance with ISO 4183 and DIN 2211 engineering standards, ensuring excellent dynamic stability, optimal mechanical balance, and long-term durability in compact machine setups.
SPC 4 Groove Pulley Key Benefits & Structural Features
- Engineered Gray Cast Iron: Cast from high-density gray iron (GG22/GG25) to resist operational wear and thermal deformation under continuous load.
- Quick-Fit Taper Bushing System: Precision-machined to accommodate standard Taper Lock Bushings (TB 3020 to TB 5050) for fast, keyless axial locking onto drive shafts.
- Precision Machine Balance: Statically balanced during production; dynamic balancing options are provided to support high-rpm rotating shafts.
- Protective Surface Treatment: Standardized with black phosphating or anti-rust primer coating for high atmospheric and moisture resistance.
- Tailored B2B Manufacturing: We offer custom OEM capabilities including non-standard bore diameters, special keyways, and customized dynamic balancing grades according to customer drawings.
Typical Industrial Applications
Our SPC 4-groove pulleys deliver reliable drive performance across various industrial sectors, including industrial exhaust fans, fluid transfer pumps, industrial agitators, grain processing equipment, and medium-duty power drive units.
