Dynamic balancing should be considered for any sheaves exceeding 5000 FPM, or if they will be used on equipment where vibration is a problem. Martin Variable Pitch Sheaves have both single and double groove designs and come with a full range of popular bore sizes including keyway and setscrew. They have a positive locking system and precision machined grooves.
