Hydraulic clamps type HSE and HSA are single-acting power elements equipped with return springs, which are used in hydraulic fixtures where only a very restricted space is available for the generation of high forces with limited piston movement. The type HSE is designed as a screw-in cylinder whereas type HSA is manifold mounting. These clamps are available, depending on application with piston diameters between 12 and 40 mm and strokes between 2 and 25 mm. They are mainly used for clamping work pieces, slides and guides, indexing round tables and for bending punching and cutting purposes.
