Product catalog summary
General Terms and Conditions: HEMA Maschinen- und Apparateschutz GmbH's clamping systems are governed by their general terms and conditions, with additional specific conditions for different products.
RotoClamp: Requires specific tolerance between shaft and clamp to prevent damage. Warranty covers 12 months or up to 1,000,000 cycles for Standard and 500,000 for Active versions, excluding emergency or brake clamping. Proof of cycles is needed for warranty claims.
LinClamp: Suitable for static and dynamic clamping. LinClamp S has a 12-month warranty or up to 1,000,000 clampings, while LinClamp A is for static clamping with a maximum of 10,000 cycles. Emergency braking is limited to 500 cycles.
PClamp: Designed for static clamping with a 12-month warranty or up to 1,000,000 cycles. Not for securing loads; warranty void if used outside specified conditions.
Operating Conditions: Recommended temperature range is 10°C to 45°C with pneumatic pressure of 4 or 6 Bar using filtered compressed air. Proper assembly and maintenance are crucial.
Product Features and Advantages: RotoClamp offers high pneumatic clamping forces and safety clamping in case of air supply failure. LinClamp is ideal for linear applications, and PClamp can be adapted for quick and safe clamping.
Technical Specifications: Detailed data is provided for RotoClamp, LinClamp, and PClamp models, including operating principles and installation recommendations.
Specifications: RotoClamp systems use compressed air at 4 or 6 Bar. Detailed measurements for shaft diameters, torque, and air requirements are included.
Procedures: Emphasizes rigid connection to machine structure. Includes steps for installing shaft flange and RotoClamp, with air application and screw tightening sequence.
Design Recommendations: Ensure accuracy of clamping surface and maintain specific tolerances for roundness and radial eccentricity.
Options and Installation: Discusses optional features like shaft flanges and guidelines for alternative air connections. Includes a request form for custom configurations.
LinClamp Systems: Compatible with various linear guide systems, offering pneumatic clamping capabilities.
Specifications and Functionality: LinClamp and PClamp systems use compressed air for clamping. LinClamp models involve spring steel sheets and clamping jaws, while PClamp systems are modular and stackable.
Research and Testing: Tests show LinClamp systems have shorter braking distances compared to alternatives, indicating superior performance.
Technical Data: Extensive data on LinClamp and PClamp models, including dimensions and holding forces.
Installation and Recommendations: Proper installation is crucial. Emphasizes rigid connection and air pressure adjustments.
Applications and Use Cases: LinClamp systems can be used as brakes and clamping elements. PClamp systems are suitable for linear and rotary loads.
Technical Specifications: Detailed specifications for PClamp systems, including holding torque and force at different pressures.
Procedures and Recommendations: Apply a safety factor of >10% to holding forces. Regular checks and monitoring are advised.
Quality Standards: All systems adhere to ISO 9001 standards, with 100% checks at production stages.
Application and Configuration: PClamp systems are suitable for various applications, with options for horizontal and vertical operations.
Additional Information: Contact information for HEMA is provided, and technical data is subject to change.

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 results...
