What are some common causes of cylinder failure?
  • Side loading – Side loading is caused from the cylinder being misaligned which creates an unparalleled force on the piston rod. A side load of enough magnitude can result in cylinder tube scoring, piston rod and rod wear bands, and seal failure.
  • Contaminated Fluid – Contaminated fluid can cause premature rod seal failure. Abrasive particles in the fluid can damage the seals and the piston rod surface, airborne contamination can be drawn into a cylinder by a faulty wiper seal. Contamination occurs in numerous ways, the most common is drawn with hydraulic oil from the pump. 

Rough or scored rod – Rough surface on the rod damages the seals and reduces their normal life resulting in the necessity for frequent replacement.
