Posi-Lock

These are mechanical shaft locks that use tapers. The wedging action of the taper surface when the clamping bolt is locked thoroughly couples the shaft and hub. The POSI-LOCK line-up includes the PSL-K (which has a collar and a small inside-to-outside ratio useful in making smaller diameter components), the PSL-G (which is highly compatible with non-Miki products), and the PSL-D (which has a medium-weight design, low surface pressure, and enables smaller and lighter mounts). Each is available in a simple anti-rust specification that uses electroless nickel plating as well as a stainless steel specification.
