Hydraulic cylinders - KC

Hydraulcylindrar - KC

Lalmek KC hydraulic cylinders are of the tie-rod type where the cylinder is screwed together with four tie-rods. This design is ideal for demanding applications where vibration and pressure peaks are common as there are no welded joints.

The hydraulic cylinders have compact installation dimensions and can be supplied with a number of different fastening options at both the piston rod end and the cylinder short end, such as spherical ends, internal or external threads or for mounting with bolted joints.

Lalmek KC can be equipped with integrated linear sensors that state the position of the piston rod with great accuracy.

The hydraulic cylinders are available in cylinder diameters up to 250 mm and press force up to 100 tons.
