The Hydraulic Online library is organised around practical engineering questions — from understanding individual components to identifying why a cylinder has failed in service.
Cylinder Components
Understand barrels, pistons, rods, glands, seals, end caps and the way the main working parts interact.
Explore cylinder parts → 02Design & Engineering
Connect specification, materials, sealing, tolerances, pressure containment and build quality.
Open the engineering guide → 03Manufacturing
Follow the real sequence from specification and machining through honing, sealing, assembly and testing.
See how cylinders are made → 04Machining & Tolerances
Explore fits, clearances, surface finish, alignment and bore quality that influence seal life and reliability.
Explore machining standards → 05Troubleshooting
Trace leakage, pressure loss, drift, scoring, slow movement and repeated faults back to likely root causes.
Troubleshoot a cylinder → 06Failure & Reliability
Recognise rod damage, seal failure, barrel wear, corrosion, bending and alignment-related failure patterns.
Explore failure modes →Search by component, symptom or process
Search the full site for the engineering term or problem you are dealing with.
Useful searches include rod damage, piston seals, barrel wear, honing, pressure loss, drift, misalignment and contamination.
