BS inquiries for reciprocating hydraulic cylinders should include the original seal drawing or sample. Repeated strokes make rod surface condition, lubrication and the pressure cycle relevant to matching. A part that fits the groove still needs an application review before it can be treated as a suitable replacement.
Typical applications
- Reciprocating hydraulic cylinder rods
- Service replacement supported by a BS drawing or sample
What to include in an inquiry
- Supply the BS drawing or a sample with its original marking
- Confirm rod diameter and all groove dimensions
- State stroke length, stroke speed and cycle frequency
- Identify hydraulic fluid, temperature and pressure peaks
- Describe rod scoring, leakage and the condition of the wiper
