Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening. As screw-clamp bushings, they're good for shock loads. When you tighten the clamping screws, the bushing's inner sleeve tightens onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.

Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.

Stainless steel bushings have excellent corrosion resistance and can withstand prolonged exposure to moisture.
