The UW Series Shock Absorber is a compact, high-performance impact damping device designed to control kinetic energy and protect equipment from the damaging effects of motion and collision in automated systems. Built with precision-engineered hydraulic damping and a self-compensating mechanism, it provides consistent and smooth deceleration of moving loads—helping improve machine reliability, extend equipment life, and reduce noise and vibration.

The UW Series features a hardened steel body, chrome-plated piston rod, and robust internal seals, offering excellent resistance to wear and corrosion. It is pre-filled with hydraulic oil and equipped with an internal return spring, allowing the piston to automatically reset after each stroke—ideal for high-speed, repetitive operations.

With energy capacities ranging from 3 Nm to 500 Nm per cycle, the UW series accommodates a wide range of applications, from light-duty positioning to heavy-load impact control. It supports impact speeds up to 3.5 m/s and offers threaded body designs (M8 to M25) for flexible and direct mounting.

These shock absorbers are used extensively in pneumatic automation, pick-and-place arms, machine tool stops, robotic grippers, and many other industrial applications where safe and controlled motion is critical.
