Rotary Hydraulic Shock Absorbers

Premium Suspension Damping for Rail Cars

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
