Page 821 | 2.4 Tensioning with Clamping Mechanisms Power Clamps Mounting Methods / Accessories The mounting holes on the main body of the power clamps have been designed to allow installation direct on the internal threaded holes or alternatively with through bolts. Centering guide bushings present an important func- tion when mounting the power clamps: they absorb lateral thrust and they ensure a precise alignment. Mounting of the cylinder by a collar clamp increases the nu- merous ways they can be installed. Even collar clamps use centering guide bushings for precise positioning. There is an extensive range of accessories available for power clamps, such as tool holders (for clamping arms) thrust bolts and clamping jaws. The sketches shown on the right give some idea. The combination of clamping tools on the clamping arm and static holders represent together a tool set. For the fixing and precise positioning of clamping arms and jaw blocks, centering guide bushings GN 870 are also used. The indi- vidual data sheets give further information. All power clamps can be fitted with proximity switches (inductive sensors) to monitor the end position of the stroke.
