Timken Belts offers the most complete line of bushings in the industry. QD, tapered bushed and MST bushings to fit all popular sheaves and sprockets are in inventory in a wide range of bore sizes.
MST® BushingsVariable Pitch Sheaves
“Quick Detachable” bushings are easy to install and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit. All sizes except JA and H have a set screw over the key to help maintain the bushings position on the shaft until the cap screws are securely tightened.
Tapered Bushed Bushings
Tapered non-flanged split bushings utilize screws to tighten on the shaft, providing excellent clamping force. Used on sprockets, sheaves and pulleys to increase clamping force over standard bored-to-size product that only utilizes a keyway and setscrew to lock onto the shaft. Their small size and the convenience and advantages of tapered construction make them of great value on many devices.
MST bushings are easy to install and remove. They are split through the barrel and have a taper to provide a true clamp on the shaft. They are keyed to both the shaft and the hub to help during “blind” installations.
