POWERGRIP - FOLLOWING THE PRINCIPLES OF THE LEGENDARY RÖHM PRODUCTS
THE KFD-HE and SZS. FROM RÖHM.
Many have learned from our power chucks and cylinders. Worldwide. Now, RÖHM presents the low-cost POWERGRIP series, which has its roots in the KFD-HE power chuck and the SZS clamping cylinder.
High speeds, a large through-hole, as well as high clamping force distinguish the POWERGRIP series. Therefore, we named them after what they can do: POWERGRIP.
