SITEMA PowerStroke FSK / FSKP Drive system for powerful forces on a short strok

Solutions for linear motion Strong focus, strong advantages SITEMA is the only company in the world that specialises in the development and production of clamping units and linear brakes on round rods in mechanical engineering. With more than 100,000 produced units to their name, SITEMA is an experienced system provider for whom absolute reliability and safe operation take priority. In contrast to SITEMA’s safety components, the PowerStroke offers an active drive based on SITEMA’s core competency – the principle of self-intensifying clamping. SITEMA’s concentration on its core competency of „self-intensifying...

SITEMA will always find a solution Clamping, holding, locking, braking or securing – a suitable product is almost always to be found in our vast standard range, with clamping units for every possible purpose. And if not, we adapt an existing clamping device, or design a new one. Individual customised special solutions can be designed even if you need just one single unit. With our help, many customers have already accomplished a new solution or an innovative product. Highest quality and functionality standards Every single product is fully tested for correct operation and clamping force Approvals:...

Clamping unit with integrated short stroke cylinder The SITEMA PowerStroke has been designed to hold and pull a clamping rod in one direction (the closing direction). It can be used in all applications that require powerful forces on a short working stroke. Forces up to 200 tons are possible on a stroke of 20 mm with a single unit, with the force being proportional to the applied closing pressure. This can be hydraulic (FSK type) or pneumatic (FSKP type). Innovation for injection moulding machines and moulding presses Working independently of the drive system, the PowerStroke resolves the conflict...

Operating principle PowerStroke clamps a smooth, round rod and The pushes it with great force at a defined rate of travel (short stroke). When the mould is being opened and closed, the PowerStroke is released (pressure at port L) and motion is not impaired. When the mould halves are in contact, the PowerStroke locks onto the rod with the proven self-intensifying clamping principle (port L pressure-free). Powerful closing force is now generated by applying pressure at port K. After the production process, the closing force is removed by re-routing the pressure from port K to L, and the mould opens...

Facts Force distribution in a confined space Compact design Small hydraulic operating volumes Independent of the drive system Separate actuation Clamping on hardened, standard piston rods SI Advantages » A lean, space-saving design is possible » Machine production costs are lower » Less energy consumption and cost » Higher productivity thanks to shorter cycle times » Asymmetric force distribution is possible » Expensive piston rods are not required Closing force at nominal pressure Special sizes, higher closing forces and longer stroke on request. Subject to modifications.
