A linear actuator comprises a piston which is provided in an actuator body and which is displaceable under a pressure fluid, a slide table which is integrally connected to the piston and which is linearly displaceable, a rod which is engaged with the slide table and which has a shaft section inserted into an engagement hole of the piston, end blocks which are connected to ends of the actuator body, and stoppers which are provided on end surfaces of the end blocks and which adjust a displacement amount of the slide table.

Linear actuator

Piston rods are coupled to respective pistons movably disposed respective cylinder chambers defined in a cylinder body. The piston rods have distal ends connected to an end plate mounted on a slide table which is mounted for movement along a guide rail. When the piston rods are displaced by the pistons, the slide table is also displaced axially of the cylinder body. When the slide table is positioned at either end of its stroke, a load is applied by the weight of a workpiece supported on the slide table and the weight of the slide table itself to the cylinder body through the guide rail. The slide table is thus prevented from being unduly flexed under the load. The length of the slide table can be set to a desired length irrespective of an increase in the displacement of the slide table. Even if the displacement of the slide table is increased, the slide table is not flexed and hence remains highly rigid against flexure.
