ACE Controls 216-0021 Pneumatic Shock Absorber

The ACE Controls 216-0021 Pneumatic Shock Absorber is a damping device that uses compressed gas to absorb energy and limit motion in moving parts. Identified by part number 216-0021 (2160021), this unit is designed to cushion impacts and control deceleration in mechanical systems where smooth, predictable stopping of components is required. As a pneumatic absorber, it dissipates energy through gas pressure, helping reduce peak forces and dampen vibrations that can accelerate wear on mounts, guides, and related hardware. In industrial applications, shock absorbers like the 216-0021 are used to manage motion events such as end-of-travel contacts and return cycles, contributing to longer equipment life and steadier operation. Because it relies on a pneumatic principle rather than hydraulic fluid, this type of absorber can offer maintenance advantages in suitable environments. Engineers reference part 216-0021 within ACE Controls' catalog to ensure correct identification and compatibility when selecting replacements or integrating with other ACE damping components.
