TROUBLE SHOOTING HYDRAULIC CYLINDERS

Hydraulic Cylinder Leakage

Hydraulic cylinders leakage occurs for a number of different reasons and it is important to identify the cause quickly so the problem can be corrected. A leaking hydraulic cylinder can lead to inefficiency, unscheduled downtime, machine damage and environmental damage if not properly identified and corrected.

Here are some common locations of hydraulic cylinder leakage and things to check for:

Location Check
1 Between Barrel
and Heads
  • O-ring for any possible damage it received during assembly
  • Surface finish of the barrel where it touches the seal
  • Groove O-ring sits in for any machine marks
  • Barrel ends to make sure they are square
2 Between Gland
Bushing and Rod
  • Condition of the rod wiper. In harsh environments wiper damage leads to containments damaging the piston rod seal
  • Wear pattern on Gland bushing. If there is only wear on one side this could be caused by side load which could damage the seal
  • Damage to surface of piston rod which could wear to seal lip
3 Between Gland
Bushing and Heads
  • Loose fit of gland bushing causing the O-ring not to seal properly. This can be caused by side load or improper machining of the gland bushing. Tight tolerance here is required
4 Ports
  • Surface finish of the heads where your hydraulic fitting connects
  • For Hydraulic cylinders SAE O-ring Boss Ports (ORB) are better than NPT for creating a seal and are highly recommended

Always review the system design requirements and make sure the cylinder is compatible for the work that is required. Westcoast Cylinder Inc. has 50 years of experience designing hydraulic cylinders for the toughest industrial applications.
