These belts follow an international standard (ISO 4184, DIN 7753) and are classified by their width and height.
| Belt Section | Top Width (mm) | Height (mm) | Angle (°) | Common Applications |
|---|---|---|---|---|
| XPZ | 9.7 mm | 8 mm | 40° | Industrial machines, compressors, pumps |
| XPA | 12.7 mm | 10 mm | 40° | HVAC systems, agricultural machinery |
| XPB | 16.3 mm | 13 mm | 40° | Heavy-duty equipment, conveyors, crushers |
| XPC | 22 mm | 18 mm | 40° | Large fans, steel mills, mining equipment |
The belt code usually follows a standard pattern:
- The prefix “X” indicates that the belt is cogged (notched).
- The letters PZ, PA, PB, PC refer to wedge belt dimensions.
- Example: XPB 2000 means:
- XPB section belt.
- 2000 mm outer length.
Note: Acceptable agreement and ex-changeability is found between 3VX and XPZ as well as between 5VX and XPB sections. It is possible to use 3VX and 5VX section belts in pulleys of XPZ and XPB sections respectively but corollary is not recommended as the top width of the RMA standard pulleys are smaller. Section 8VX is however, larger than XPC.
FEATURES:
- Oil resistant and anti-static
- High power transmission capacity than wrap belts
- Superior transverse stiffness & high wear resistance
- Suitable for drives with small pulley diameters, high ambient temperature and speed
- Temperature range: -30°C to +100°C
