Mechanical (Posilock Friction Pack)

This mechanical shaft lock utilizes a tapered design; when the clamping bolt is tightened, the wedge action of the tapered surfaces ensures a secure, permanent connection between the shaft and the hub. We offer several models designed for various load capacities and to ensure compatibility with other manufacturers' products. Each model is available in a variety of options, including a basic anti-corrosion version with electroless nickel plating and a stainless steel version.

Specifications This mechanical shaft lock, featuring a tapered design that offers high compatibility with other manufacturers' products, is capable of withstanding heavy loads. This mechanical shaft lock features a tapered design for high compatibility with other manufacturers' products and is finished with electroless nickel plating. This mechanical-type shaft lock is designed for medium loads and features a low contact pressure, enabling the use of smaller diameters. This mechanical-type shaft lock is designed for medium loads to minimize contact pressure and features an electroless nickel plating finish. This shaft lock, which uses a flange to allow for a smaller inner-to-outer diameter ratio between the shaft and hub, ensures high concentricity. This shaft lock, which uses a flange to allow for a smaller inner-to-outer diameter ratio between the shaft and hub, features a hex bolt design.
