Application

Tapered split clamping bushing that locates and locks the V-belt pulley or gear onto the shaft with a press fit, allowing easy pulley removal.

Installation Notes

Clean the tapered surfaces and apply light oil; tighten the clamping bolts evenly in a diagonal sequence until the required fit is achieved; mark the position for reassembly.

FAQ

How does the taper bushing lock the pulley?
The split tapered bushing is pulled into the pulley bore by the clamping bolts, compressing it radially onto the shaft to create a keyless press fit.
Can the same bushing fit different pulley bores?
No, the bushing is matched to a specific bore and taper series; provide the pulley part number or shaft diameter when ordering.
How do I remove a seized taper bushing?
Use the ejection/extracter threaded holes in the bushing, loosen the clamp bolts and screw the ejector bolts alternately to push the bushing out.
