XPA - Narrow profile toothed V-belts

XPA profile belts are toothed V-belts used in industrial drives, agricultural machinery and other mechanisms where high transmission capacity and durability are required. Here are the main characteristics and features of these belts:

Typical dimensions:
✔ Width (top) - 12.7 mm
✔ Height - 10 mm
✔ Minimum pulley diameter - 63-71 mm

Belt length:
Indicated as XPA XXXX, where XXXX is the length along the design (working) line Lw in millimeters.
Other types of lengths:
La - external length
Li - internal length

Features and benefits
✔ Toothed design: Provides better cooling, reduces heating and increases service life compared to conventional V-belts.
✔ High transmission power: Can transmit 70% more power than similar belts without teeth.
✔ Works on small pulleys: Allows for compact drives.
✔ Compatibility: Suitable for SPA (standard V-belt) pulleys

Disadvantages
- Higher cost compared to non-toothed belts.
- Require more precise tensioning for optimal operation
