    • A linear actuator is provided to selectively change an installation direction of a cylinder body with respect to a slide table according to use environments without increasing a size of the cylinder body. A linear actuator includes a cylinder body(12), a slide table(14), a cylinder mechanism, and a guide mechanism(18). The cylinder body has a cylinder chamber to receive pressure fluid, one side surface(28) extended in an axial direction and having fluid inlet/outlet ports, the other side surface(26) having an installation groove(46), and a pair of guide surfaces(22,24) arranged orthogonal to the side surfaces. A detecting unit to detect a displacement amount of a piston inside the cylinder chamber is installed in the installation groove of the other side surface. The slide table faces one of the guide surfaces and is freely displaced in the axial direction of the cylinder body. The cylinder mechanism reciprocates the slide table under the displacement of the piston inside the cylinder chamber. The guide mechanism has a guide block(118) attached to one of the guide surfaces, rolls a plurality of rolling bodies(126), and has a circulation passage to guide the slide table in the axial direction of the cylinder body. The guide mechanism is detachably installed on the guide surfaces.
    • 提供线性致动器以根据使用环境选择性地改变气缸体相对于滑动台的安装方向,而不增加气缸体的尺寸。 线性致动器包括缸体(12),滑动台(14),气缸机构和引导机构(18)。 气缸本体具有容纳压力流体的气缸室,沿轴向延伸的一个侧表面(28)并具有流体入口/出口,另一侧表面(26)具有安装槽(46)和一对 引导表面(22,24),其布置成与侧表面正交。 在另一侧面的安装槽内安装有用于检测气缸室内的活塞的位移量的检测单元。 滑动台面朝向导向面之一,并且在气缸体的轴向方向上自由移位。 气缸机构在气缸室内的活塞位移下使滑动台往复运动。 引导机构具有安装在一个引导面上的引导块(118),滚动多个滚动体(126),并且具有沿着滚筒体的轴向引导滑动台的循环通道。 引导机构可拆卸地安装在引导表面上。
