Clamping systems Warranty Warranty conditions for clamping systems The general terms and conditions of HEMA Maschinenund Apparateschutz GmbH apply; these can be viewed at www.hema-schutz.de. The following additional points apply to the clamping system range of products: RotoClamp Due to its construction, the tolerance range of the RotoClamp (tolerance: cylindricity) between the shaft and the clamp must be maintained within the defined range; a deviation from this range may result in damage to the housing or the diaphragm when in continuous operation. A deviation from the tolerance range...

Clamping systems RotoClamp RotoClamp Inside RotoClamp Outside

RotoClamp Advantages Pneumatic clamping with high forces RotoClamp Safety clamping RotoClamp Standard – If the air supply fails then system clamps The values of hydraulic clamping are reached and exceeded Low system costs in comparison to hydraulics Simple installation Compact design Suitable for all shaft sizes

Clamping systems Comparison of operating principles Hydraulic clamping Rotating tabletop Pneumatic clamping Rotating tabletop RotoClamp Chamber with hydraulic oil Operating principle of hydraulic clamping Operating principle of the RotoClamp Function The chamber formed by the expansion ring and the O-ring is supplied with hydraulic oil. The upper ring of the expansion ring is pressed upwards and away elastically and clamps the rotating brake disk between the fixed expansion and counter rings. Standard table sizes with 500 x 500 mm pallets achieve approx. 3000 to 4000 Nm holding torque at 80...
