Custom V Belt Pulleys for Elevator Parts Casting Services for Sale

In elevator and vertical transportation systems, V-belt pulleys serve as critical power transmission components that ensure smooth, reliable operation. Our custom casting services specialize in producing high-performance V-belt pulleys specifically designed for elevator applications, combining advanced manufacturing techniques with rigorous quality control to deliver components that meet the stringent requirements of the vertical transportation industry.

Material Selection and Performance Characteristics

We utilize premium materials including high-strength cast iron grades (GG25, GG30) and aluminum alloys (A356-T6) to meet diverse application requirements. These materials provide:

• Cast Iron Pulleys: Excellent wear resistance with tensile strength of 250-300 MPa, superior vibration damping characteristics, and Brinell hardness of 180-250 HB

• Aluminum Alloy Pulleys: High strength-to-weight ratio with tensile strength of 234-262 MPa, corrosion resistance, and reduced rotational inertia

The groove geometry is precision-engineered to ensure optimal belt contact, minimize slippage, and extend both pulley and belt service life in continuous elevator operation.

Advanced Manufacturing Process

Our comprehensive manufacturing approach integrates multiple technologies:

Precision Casting Process:

• Pattern making using CNC machining for accurate groove profiles

• Shell molding and green sand casting processes

• Controlled melting and pouring at 1380-1450°C for cast iron, 710-750°C for aluminum

• Stress relief annealing and normalizing heat treatments

CNC Machining Operations:

• 5-axis machining centers for complex groove geometries

• Precision boring of hub and keyway features

• Dynamic balancing to G6.3 grade at operational speeds

• Critical dimension control:

  • Groove angle accuracy: ±0.5°

  • Pitch diameter tolerance: ±0.1mm

  • Bore diameter: H7 tolerance

  • Surface finish: Ra 1.6-3.2μm on groove surfaces
