3. What is the working pressure range of 557/60078 Hydraulic Cylinder ?

The 557/60078 Hydraulic Cylinder is designed for medium and high-pressure hydraulic systems:

• Rated continuous working pressure: 210 bar (3045 PSI)

• Maximum intermittent peak pressure: 250 bar (3625 PSI)
  
  

4. Can 557/60078 Hydraulic Cylinder replace other brands?

• Full interchange with original JCB OEM numbers: 557/60141, 557/60237, 576/60124, same mounting dimension, bore/rod size 90×50mm, port position and stroke as genuine JCB parts.

• It replaces mainstream aftermarket brand cylinders made for JCB 3CX/4CX front bucket lift ram from European, Turkey and Chinese spare part manufacturers, matching 210bar rated working pressure standard.

• Cannot fit or replace cylinders of other equipment brands (Case, Cat, Komatsu etc.), as their installation spacing, pin size and overall length differ entirely.
  
  

5. What hydraulic oil is recommended for 557/60078 Hydraulic Cylinder ?

• Extension speed (bucket lifting): 0.12 ~ 0.22 m/s (7.2 ~13.2 m/min) under normal loaded working condition

• Retraction speed (bucket lowering): 0.19 ~0.32 m/s (11.4 ~19.2 m/min); retraction is ~1.6× faster than extension due to rod area reduction

• Max allowable limit speed: ≤0.35 m/s to avoid seal wear and end impact; no-load transient speed may hit 0.38 m/s temporarily
