A slide rail assembly includes first and second rails, a ball bearing assembly, and a damping device. The first rail has front and rear ends and a middle portion therebetween. The second rail is displaceable with respect to the first rail. The ball bearing assembly is movably mounted between the front and rear ends of the first rail and includes a ball retainer with a plurality of balls and a stopping feature. The damping device is mounted on the middle portion of the first rail to provide a damping force corresponding to the stopping feature of the ball retainer. The ball retainer can be displaced by the second rail such that the stopping feature of the ball retainer contacts the damping device.

In this motion guide device (10), a track member (20) has a recess or protrusion (51) that is formed in a longitudinal direction, and a moving member (30) has a holding protrusion or holding recess (53) that corresponds to the recess or protrusion (51) formed in the track member (20). When force is applied in a direction that would cause relative separation of the moving member (30) and the track member (20), the holding protrusion or holding recess (53) holds onto the recess or protrusion (51) such that the moving member (30) and the track member (20) are unable to be separated. With this configuration, a motion guide device that is both compact and capable of withstanding a strong external load can be obtained.

A slide rail assembly includes a first rail, a second rail and a driving mechanism. The second rail is movable relative to the first rail. The second rail includes an engaging feature. The driving mechanism is arranged on the first rail. The driving mechanism includes a housing, a movable member, an actuating structure and an elastic member. The movable member is movable relative to the housing. The actuating structure is arranged on the movable member. The elastic member is configured to provide an elastic force to the movable member. Wherein, the actuating structure includes a first part and a second part. Wherein, the first part is configured to engage with the engaging feature of the second rail, and the second part is configured to prevent the engaging feature of the second rail from being disengaged from the first part.

A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.
