How to Select the Right SPZ Wedge Belt

Choosing the correct belt ensures optimal performance and extended equipment life. Follow these steps when selecting your SPZ belt:

1. Measure the Belt Length

  • Measure the inner circumference of your current belt.
  • Use a flexible measuring tape or a belt-measuring tool.
  • Avoid steel rulers or metal tapes, as they distort lengths.
  • Straighten the measuring tape after looping to obtain the correct size.

2. Check Width and Height

  • SPZ belts feature a standard trapezoidal profile.
  • Confirm dimensions: 10 mm top width and 8 mm height.
  • Ensure the belt fits your pulley groove without slipping or riding high.

3. Match with Manufacturer Specifications

  • Refer to equipment manuals for belt codes
  • Or match pulley markings (e.g., SPZ, SPZ1120, SPZ1250)

Common Applications of SPZ Belts

SPZ belts are widely used across industries such as:

  • Automotive alternators & auxiliary systems
  • Industrial motors, pumps & compressors
