Rotary clamp has improved accuracy

Third Quarter 2008 Pneumatic systems & components

The MK2T rotary clamp cylinder is an addition to SMC's compact and lightweight MK pneumatic rotary clamp cylinder series. Rotary clamp cylinders are typically used to clamp parts together during a welding process. SMC's rotary clamp cylinders are equipped with piston rod scrapers to help extend cylinder life by removing contaminants from the piston rod. They are also equipped with a magnetic piston and can be fitted with direct mount auto-switches for end of stroke position sensing capability. The company's rotary clamp cylinders include the MK, which is considered a standard duty rotary clamp cylinder, and the MK2, which is considered a heavier duty design than the MK.

The design of the rotational mechanism in the newest addition, MK2T, is a double guide type. This gives the new model three times the moment of inertia capability over the MK2 and ten times the moment of inertia capability over the MK. The two-roller mechanism also allows the MK2T to be mounted horizontally, which was not allowed in the previous versions. The new clamp cylinder also features improved non-rotating accuracy as well as a tighter rotation angle tolerance than previous series.
