The operation of the power clamping nuts of the MCA-S and MCA-T series is completely tool-free. The clamping nuts expanded by a star (MCA-S) or T-handle (MCA-T) enable uncomplicated operation by hand. The force amplification is achieved via the integrated planetary gear, so high clamping forces are very easy to achieve.
The automatic switchover from pre-tensioning to power tensioning is ensured by automatic switching. Thanks to their robust construction and the self-locking function of the power clamping nuts, a high degree of safety can be guaranteed. Made of nitrocarburized heat-treated steel and provided with an aluminum housing cover, they can be used at operating temperatures from -30 ° C to + 90 ° C.
