V Belt Size Calculator for Lifting Weights
Here's a comprehensive table detailing V-Belt sizes for lifting weights, covering belt types, dimensions, and specifications:
| Belt Type | Top Width (in/mm) | Thickness (in/mm) | Angle (°) | Typical Length Range (in) | Applications in Lifting |
|---|---|---|---|---|---|
| A (Classical) | 0.5 in (13 mm) | 0.3125 in (8 mm) | 40° | 18 - 100 in | Light-duty lifting machines, pulleys |
| B (Classical) | 0.66 in (17 mm) | 0.406 in (10 mm) | 40° | 23 - 200 in | Medium-duty lifting equipment, hoists |
| C (Classical) | 0.88 in (22 mm) | 0.531 in (13 mm) | 40° | 35 - 240 in | Heavy-duty lifting, cranes, winches |
| D (Classical) | 1.25 in (32 mm) | 0.75 in (19 mm) | 40° | 50 - 300 in | Industrial-grade lifting, conveyors |
| E (Classical) | 1.50 in (38 mm) | 0.875 in (22 mm) | 40° | 70 - 400 in | Large lifting machines, high torque applications |
| 3V (Narrow) | 0.38 in (9.5 mm) | 0.31 in (8 mm) | 40° | 25 - 200 in | Compact lifting equipment, motor-driven lifts |
| 5V (Narrow) | 0.62 in (16 mm) | 0.53 in (13.5 mm) | 40° | 35 - 250 in | Medium-duty hoists, pulley-driven lifts |
| 8V (Narrow) | 1.00 in (25 mm) | 0.89 in (23 mm) | 40° | 50 - 400 in | Heavy lifting, large-scale lifting applications |
| AX (Cogged A) | 0.5 in (13 mm) | 0.31 in (8 mm) | 40° | 18 - 100 in | Higher flexibility for lifting pulleys |
| BX (Cogged B) | 0.66 in (17 mm) | 0.41 in (10 mm) | 40° | 23 - 200 in | Energy-efficient lifting systems |
| CX (Cogged C) | 0.88 in (22 mm) | 0.53 in (13 mm) | 40° | 35 - 240 in | High-power lifting winches |
| Poly-V (J, L, M) | 0.09-0.38 in (2.3-9.5 mm) | Varies | Varies | Custom lengths | High-speed, smooth lifting applications |
Choosing the Right V-Belt for Lifting:
- Consider Load Capacity: Higher torque applications need wider, thicker belts like C, D, E, or 8V.
- Space Constraints: If space is tight, narrow V-belts (3V, 5V, 8V) offer more power in a compact size.
- Efficiency & Heat Resistance: Cogged (AX, BX, CX) and Poly-V belts reduce slippage and improve efficiency.
- Pulley Compatibility: Match the belt type to your pulley groove dimensions.
