Shaft couplings consist of just two components

Paul Boughton
A new M-Type Shaftloc rotating component fastening device from Stock Drive Products (SDP) is used for rigidly mounting hubless gears, sprockets, pulleys, cams or any thin-walled components onto metric or imperial shafts. This device features infinite radial and axial adjustments and a quick lock and release action.

Shaftloc benefits from simplicity, in that it contains all structural features in only two parts. Due to its asymmetric thread geometry, a large radial clamping force is produced when the nut is tightened. It is a precision, dynamically balanced product that is suitable for high-speed applications. This simple two-piece keyless fastener can be installed within seconds, thereby reducing assembly costs. Tightening the nut causes the slotted sleeve to contract and grip the shaft, thereby clamping the part to the sleeve at the same time. Shaftlocs can be installed on shafts with existing keyways. Standard tools can be used and the Shaftloc is reusable.

Shaftloc devices are available from stock to fit 10, 14 and 16mm metric shafts and 0.375, 0.500 and 0.625inch imperial shafts. All-stainless steel versions are available for applications requiring improved corrosion resistance.
