Flush-Mount Screw-Clamp Bushings


Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads and have higher torque ratings than self-centering bushings. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.
