M-Type Shaftloc Rotating Component Fastening from SDP

The M-Type Shaftloc rotating component fastening device from Stock Drive Products (SDP), an ISO 9001 manufacturer, is used as a locking device for rigidly mounting hubless gears, sprockets, pulleys, cams or any thin-walled components onto an inch or metric shaft. They feature infinite radial and axial adjustments and quick lock and release action. 

Shaftloc contains all structural features in two parts. Due to its asymmetric thread geometry, a large radial clamping force is produced when the nut is tightened. It is a precise, dynamically balanced product suitable for high-speed applications. The two-piece keyless fastener can be installed in seconds, reducing assembly costs. Tightening the nut causes the slotted sleeve to contract, gripping the shaft and clamping the part to the sleeve at the same time. The device is reusable and can be installed on shafts with existing keyways, without marring them, and using standard tools.

Other advantages of the Shaftloc system include applicability to small shaft diameters, availability in all stainless construction and the ability to use them for stationary breadboard structures. Shaftloc is available from stock to fit .375", .500" and .625"; 10 mm, 14 mm and 16 mm shafts.
