Features

Supports a wide variety of impact masses
Supports a wide range of impacting objects, from grams (g) with the M4 size to tons (t) with the M48 size.

Supports a wide variety of impact speeds
Supports maximum impact speeds of 0.8 m/s to 3 m/s.

Stopper nut not needed
Workpieces directly contact the end of the body, so there is no need for mounting a stopper nut. Mounting is easy and saves space.

Body is entirely threaded
Entire body is threaded to maximize the range of installation positions and also improve heat dissipation.
Note: Except for M4 and M6 (10-32UNF, 1/4-32UNEF) sizes.

Supports high cycle times
Reduces the time from impact to end of operation. Even if the workpiece mass and speed changes, our original linear orifice construction automatically adjusts to prevent wasted operation time. Combined with reduced vibration, this contributes to improved productivity.

Silent design
Reducing the impact value at collision decreases the noise at workpiece impact.

Short stroke type
Perfect in low-speed range for shock absorbing in limited spaces.

Long stroke type
Making the absorbing stroke longer allows for softer absorption of shocks.
