SPZ V-Belt Size Chart

Specification	SPZ Belt
Top Width	10 mm
Depth	8 mm
Typical Length Range	425 mm – 3550 mm

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
