Overview
Pearson Manufacturing repairs and rebuilds industrial hydraulic cylinders across tie-rod, welded, and telescopic designs. We coordinate diagnostics, machining, sealing, testing, and QA under a single work order so your cylinder returns to service quickly and reliably.
*Scope and lead times vary by damage and parts availability. We’ll confirm achievable options after review of your photos/specs.
Quick Specs
| Option | Scope | Speed | When to Choose |
|---|---|---|---|
| Repair | Seal swap, polish rod, minor parts | Fastest | Best when wear is limited and tube is sound |
| Rebuild | Full reseal, hone tube, new rod/eye/bearing | Fast | Restores performance; cost-effective vs new |
| Remanufacture | New barrel/rod from print, reuse end-caps | Medium | Ideal when tube is scored or bent |
| New Build | Custom cylinder to spec | Medium | When legacy parts unavailable or upgrade desired |
Repair & Rebuild Services
- Disassembly, inspection, and failure diagnosis
- Seal measurement and replacement (OEM-matched or upgraded compounds)
- Rod straightening or replacement; hard-chrome & polish (Ra per spec)
- Tube honing / boring to restore surface and concentricity
- End-cap, gland, and clevis repair or remanufacture
- Thread repair, keyway repair, pin & bushing replacement
- Pressure / leak testing with documented results
- Paint/touch-up and final QA under Pearson procedures
Our Process
- Intake & Triage — confirm bore, stroke, ports, mounting style, and symptoms (leak, drift, low force).
- Disassembly & Clean — protect mating surfaces; capture photos for traceability.
- Inspection — measure rod runout, tube ID, wear bands, bearing fits; check eye/cap threads and ports.
- Quotation — options for repair vs. rebuild vs. remanufacture with lead time and warranty terms.
- Machining — hone/boring, rod manufacture or straightening, thread repair, bushing press-fit, surface finish.
- Reassembly — install new seals (material per temp/pressure/fluids), torque to spec, verify stroke.
- Testing — hydro/pressure test, leakage and drift checks; document results on request.
- Final QA & Ship — paint/touch-up, cap ports, pack for transit; optional on-site fit support.
Design for Maintainability & Prep
- Provide photos of nameplates and ports; list bore × stroke × rod diameter and mounting style.
- Share operating pressure, fluid type (e.g., ISO VG hydraulic oil), and temperature range to select seal compounds.
- Note failure symptoms (external leak, bypass/drift, side-load wear) and any rod damage or corrosion.
- If possible, include the gland/end-cap and clevis dimensions; bring mating pins for fit check.
- Flag cleanliness requirements (e.g., flush/clean prior to installation) and paint/finish expectations.
We confirm achievable specs and testing requirements before kickoff.
Common Failure Modes
- Seal wear/thermal hardening leading to external leaks
- Rod scoring or pitting causing premature seal damage
- Barrel scoring/ovalization causing bypass and drift
- Bent rod from side loading or misalignment
- Bearing/wear ring failure leading to metal-on-metal contact
Industries We Serve

Hydraulic Cylinder Repair FAQs
What info do you need to quote a cylinder repair?
Send bore × stroke × rod diameter, cylinder type (tie-rod/welded/telescopic), mounting style, port type/size, photos, and failure symptoms. A short video of the issue helps too.
Do you pressure test rebuilt cylinders?
Yes. We can perform hydro/pressure testing and leak checks to your required pressure. Results can be documented on the work order when requested.
Can you fabricate a new rod or barrel?
Yes. We routinely manufacture new rods (with thread/eye) and remanufacture barrels with honing/boring to restore proper clearance.
What seal materials do you use?
We match OEM profiles and can upgrade materials per environment: NBR for general use, FKM for higher temperature/chemicals, PTFE for low friction, and polyurethane for abrasion.
How fast is a typical turnaround?
Standard repairs complete in about 5–10 business days depending on parts and scope. Rush service may be available—note your deadline on the RFQ.
Need a Cylinder Back in Service Fast?
Send bore × stroke × rod size, photos, and symptoms. We’ll provide options for repair, rebuild, or remanufacture with lead times.
