Completely tool-free clamping is possible with the two power clamping nuts ESBS and ESBT from ENEMAC.
The power clamping nuts of the ESBS and ESBT series with their integrated planetary gear can be driven easily and with little effort by turning the hand grip. The internal thread is drawn in a little and the counterpart is tightened when turning the handle.
Up to 40 t clamping force can be generated manually.
And this is how it works: Manually screw the power clamping nut onto the existing bolt until the nut lies flat on the part to be clamped. Then turn the handle clockwise until the workpiece is firmly clamped. The nuts are self-locking and guarantee a high level of security.
The ESBS and ESBT series are designed for workpieces or tools of the same size. Both types are available as standard for thread sizes from M10 to M20 and can be used at temperatures between -243 K and 363 K.
