Shaft Locking Clamps

Fixtureworks^® (Fraser, MI) a leading North American manufacturer and supplier of clamps, fixturing accessories, machine tool components and rollers & bumpers, now offers a lineup of both manual and pneumatic shaft locking clamps.

Shaft locking clamps are designed to positively lock a shaft and/or spindle quickly without the use of tools. They are ideal for applications where frequent disassembly and changeover are needed. The clamps can be used in smaller spaces than conventional shaft collars, offering much better workability as there is no need to tighten levers or screws.

The variety of manual shaft locking clamps come in two versions: A plastic body with steel or plastic knob for locking, and a zinc body with vertical handle for locking. In the first version the knob is turned to lock in the shaft. In the other version a simple vertical handle motion is used. The handle is moved down for clamping. For releasing, the handle is moved up. Set screws and adjustable handles are not needed in either version. Manual shaft locking clamps are used for shaft diameters from 8 to 20 mm and holding torque of 1.4  to 4.7 ft.lb.

Pneumatic Shaft-Locking Clamps are designed for quick change applications. In the pneumatic version, when connected to air, the clamp allows clamping/unclamping in one operation. They are perfect for secure clamping of sliding shafts and for use on machines where many clamping or unclamping cycles are run, or for multi-clamping applications. With air supply, remote operation is also possible at places out of reach, or hidden places like the backside of machines, and for maintenance or machine appearance.

The mechanism of spring-pressure clamping, and air-pressure unclamping prevents any decrease of shaft-locking force any operator can do uniform clamping. They work under operating air pressure of 43-100 psi and can handle shaft diameters from 10-30 mm.
