A TL (taper lock) bushing creates a secure, interference-fit connection between a shaft and a mounted component, without the flange of a QD bushing, for a lower-profile fit. 3BG Supply stocks taper lock bushings across standard TL sizes and bore ranges, alongside our split taper bushings and full bushings line. Not sure which TL size matches your sprocket or pulley bore? Our team can help you cross-reference it.

FAQs
What is a taper lock bushing?
A taper lock bushing provides a secure, interference-fit connection between a shaft and a mounted component such as a sprocket, pulley, or sheave, without the flange found on a QD bushing. It relies on a frictional taper fit to hold the assembly in place with minimal movement.
How does a taper lock bushing work?
Tightening the bushing's mounting bolts pulls the split, tapered sleeve into the matching tapered bore of the hub, compressing it around the shaft to lock the two together. The result is a rigid, vibration-resistant connection without a separate keyway fit being required for torque transfer.
How do I read a taper lock bushing size chart?
A taper lock bushing size chart lists bore diameter, outside diameter, and TL series designation (such as 1610, 2012, or 3030), which you need to match both the shaft and the hub bore. The series number also indicates the bushing's length and torque capacity.
How do I install a taper lock bushing?
Insert the bushing into the hub, thread the mounting bolts into the tapped holes, and tighten them evenly in stages to draw the taper together without cocking the bushing. Follow the torque spec for your specific TL series to avoid over- or under-tightening.
How do I remove a taper lock bushing?
Remove the mounting bolts and reinsert them into the threaded jack-out holes on the bushing flange, then tighten evenly to push the bushing back out of the tapered bore. This backs the bushing out without needing a separate puller tool.
Is there a difference between a taper lock bushing and a QD taper lock bushing?
The terms are often used interchangeably in casual conversation, but a standard TL bushing has no flange while a QD bushing does. If your part number references a flange with multiple bolt patterns, you are likely looking at a QD design rather than a true TL bushing.
