MVP® Sheaves
Features:
- Available in both Classical and Narrow Belts
Classical Belt Offering: A, B, & C - 2 to 5 grooves
Narrow Belt Offering: 5V - 3 to 5 grooves
- Lean manufacturing technique allows for not stock MVP sheave sizes to be built in 3 to 5 days.
Benefits:
We have a large selection of sheave products. We also make available the best product for specific applications and most economical drive design.
MVP® sheaves are a series of angular faced center flanges which are bolted to the fixed flange mounted on the barrel. They also contain another series of angular faced flanges which are bolted to the end flange and threaded locking collar.
When the threaded locking collar is turned clockwise, it moves the angular flanges closer together increasing the pitch diameter. When the collar is moved counterclockwise, the flanges are moved apart, decreasing the pitch diameter. The pitch diameter is infinite. This means the collar adjustment can be turned and stopped at any time regardless of location between the minimum and the maximum setting.
When the desired diameter is obtained, the locking collar is locked by tightening screws. In contrast, VL, VP, and VM sheaves are limited by "half-turn" or 180-degree adjustment points.
