PSL-D(C) Electroless Nickel Plating Type

This mechanical shaft lock utilizes a tapered design; by tightening multiple clamping bolts, the tapered surfaces create a wedge effect that fully secures the shaft and hub together. Since the shaft and hub are joined by friction, this design overcomes the drawbacks of keyed connections. Designed for medium loads, this shaft lock minimizes contact pressure and features an electroless nickel plating finish.
