The demand for improved ride quality and increased durability makes Enidine’s Rotary Shock Absorber (RSA) the perfect choice to control vertical andlateral motion in rail suspension applications. RSA’s are built to outlast and outperform linear type shock absorbers, offering the best ride quality available today.

The unique RSA is a vane type shock absorber. The fluid-filled opposing chambers are interconnected through a metering valve. Rotational force applied to the end of the wingshaft displaces the fluid from the high-pressure chamber to the opposing low-pressure chamber. This causes a resistance to relative motion and damping of the input force. The amount of damping torque is governed by angular velocity of the load applied to the shock absorber and by the valving settings.

Rebuildable Design allows for factory-direct reconditioning extending service life
A Variety of Installation Arrangements solve difficult application problems
Spring-Loaded Dynamic Shaft Seal prevents external leakage and provides continuous selfadjustment for service wear
External Access to Fluid Reservepermits periodic check of fluid level
Resistant to Deterioration caused by water, dirt, or corrosive action increasing dependability of operation
Automatic “High Shock” Relief Valves protect components from damage due to instantaneous shock loads and limit torque developed in operation
Uniform Damping Characteristics over wide temperature ranges are achieved with an automatic temperature-compensating valve
Factory-Adjustable Valving allows changes in damping resistance to meet application requirements or to compensate for wear
Completely Self-Contained Design
