Standard version:
SB Clamping bushing
Made of chrome/nickel steel and hardened to approx. 62 Rockwell, highly elastic and with a large opening stroke for the easy loading of work pieces. And a superb dampening effect that prevents vibration from occurring. Thanks to the unique HAINBUCH rubber-metal vulcanization process this version is very efficient, even under the most extreme conditions – that is especially true on mandrels for small diameters or short clamping length.

Optional version:
SAD Clamping Bushing for in-house machining
Made of steel hardened to approx. 50 Rockwell. In an emergency or for small lot sizes, these clamping bushings can be machined to the required diameter. The support ring to accomplish this is included.
