Split Taper Bushing

A split taper bushing uses a slotted, tapered sleeve to grip a shaft tightly while still allowing for easy removal and replacement, which is why it remains a mainstay in industrial power transmission. 3BG Supply carries split taper bushings, including Browning-style parts, across the full range of standard bore sizes, and they mount into the same hubs as our QD bushings. Check our bushings category for the full lineup, or reach out for help matching a bushing to your sprocket or pulley.

    FAQs

    What is a split taper bushing?

    A split taper bushing is a slotted, tapered sleeve that compresses around a shaft as its mounting bolts are tightened, locking a sprocket, pulley, or sheave in place. The split design lets the bushing flex slightly for a tight, vibration-resistant grip.

    How do I read a split taper bushing size chart?

    A split taper bushing size chart lists the bore diameter, outside diameter, and bushing series (such as SH, SD, or SK), so you can match the bushing to both your shaft size and the hub it mounts into. Two bushings can share a bore size but differ in series, so always confirm both figures.

    How do I install a split taper bushing?

    Slide the bushing into the tapered bore of the hub, insert the mounting bolts, and tighten them evenly in a crossing pattern to draw the bushing in and compress it against the shaft. Uneven tightening can cock the bushing, so work in small increments across all bolts.

    What types of split taper bushings are available?

    3BG Supply stocks split taper bushings in multiple series and materials, including standard steel and Browning-style parts, covering a wide range of inch and metric bore sizes. Our bushings category page lists current stock by brand and series.

    What's the difference between a split taper bushing and a QD bushing?

    Both use a tapered, split sleeve, but a QD bushing adds a flange with two sets of bolt holes for fast standard or reverse removal, while a split taper bushing typically has a single bolt pattern. The QD design trades a slightly larger footprint for quicker maintenance.
