Construction:
- 1. Canvas Top.
- 2. Adhesion rubber.
- 3. Tensile cord.
- 4. Rib rubber.
Features:
- Compact design. More compact design is possible because RIB ACE II can be used with smaller pulleys.
- High-speed operation. Suitable for high-speed applications up to 50m/s as there is little centrifugal force related loss.
- Highly accurate with little belt vibration. Due to the manufacturing process used (grinding) the ribs are all connected resulting in smooth running and less rotational unevenness.
- Highly efficient transmission (Low power loss). Compared to V-Belt, RIB ACE II is thinner and has less flexion loss resulting in high transmission efficiency.
- Low maintenance owing to a stable tension. Due to better deformation and abrasion resistance than V-belts, RIB ACE II is less likely to sink into pulleys meaning longer periods between maintenance.
