ABSTRACT:
The invention relates to a linear motor with a cylinder (5) containing a piston linked to a piston rod (8) projecting from either of the end faces of the cylinder (5). To secure the piston rod against torsion and rotation, a guide comprising at least two guide ribs (22, 22') arranged on the circumference of the cylinder (5) is provided, these ribs being arranged at a distance from each other and extending in the axial direction of the cylinder (5). A slide (19) seated on the outside of the cylinder (5) and guided on the guide ribs (22, 22') while at least partially encompassing them is fixed to the piston rod (8).
