The UD Series Shock Absorber is a high-performance, adjustable damping device engineered to manage impact energy in heavy-duty industrial and automation applications. Unlike fixed-type absorbers, the UD series offers external adjustability, enabling users to fine-tune the damping force for different impact speeds, loads, and operating conditions.

Built from hardened steel and treated with an anti-corrosive coating, the UD series features a chrome-plated piston rod and precision internal oil flow control system, delivering smooth, stable deceleration even under high-speed, high-force impacts.

Designed to absorb energy up to 1200 Nm per cycle, the UD Series supports stroke lengths from 10 mm to 100 mm, making it ideal for press machines, robotic end-effectors, gantry loaders, and high-speed packaging lines. It operates efficiently across impact speeds of 0.05 to 5 m/s, ensuring both shock isolation and machine protection in every cycle.

Equipped with an internal return spring, the piston rod resets automatically, enabling fast and repeated operation without delay. The adjustment dial allows for quick setup and on-site fine-tuning, making the UD Series suitable for variable-load environments.
