| Function STTEMA locking devices clamp a rod in an infinitely variable manner, without altering its position, and hold axial forces in both directions. Clamping is released depending on the type, by either hydraulic or pneumatic pressure. Clamping force generation takes place either through the action of springs or through hydraulic pressure and is increased by ciLI'oi' conical surfaces o; asymmetrical levels. Properties ■ Holding forces from 1 kN to 1500 kN ■ Hydraulic or pneumatic control • Clamping without axial play in both load directions ■ KFHW. KFHC and KFPC suitable for emergency braking function Applications ■ Sheet metal rotling mills ■ Steel industry and hydraulic engineering ■ Special machines |
