Hydraulic Cylinder Manufacturing, Repair & Maintenance in Sharjah and Across the UAE
ASAT repairs hydraulic cylinders at our workshop in Sharjah Industrial Area 13 for customers across the UAE. Every job follows the same path: full teardown, measurement, a written quote, repair by resealing, honing, rechroming or machining new parts, then a pressure test on our bench before the cylinder goes back. We also manufacture new hydraulic cylinders to customer drawings.
Signs your hydraulic cylinder needs repair
- The boom, arm or bed drifts down under load.
- Oil weeps or sprays past the gland or rod seal.
- The chrome rod is scored, pitted or bent.
- The cylinder moves slowly, jerks or loses force.
- The hydraulic oil runs hotter than usual (internal bypass).
Comprehensive overhaul, barrel honing, rod reconditioning & leak-free sealing
ASAT manufactures new hydraulic cylinders to customer drawings, and delivers specialized workshop overhaul and restoration for all types of hydraulic cylinders operating in heavy industrial, earthmoving, and transport environments across the UAE. From repairing scored cylinder rods and damaged barrels to machining custom gland nuts and fitting high-specification polyurethane seal packages, every cylinder is returned to reliable service after thorough pressure verification.
- Single-acting, double-acting & multi-stage telescopic cylinders
- Cylinder rod micro-polishing & hard chrome plating restoration
- In-house lathe machining for damaged gland threads and custom pistons
Our hydraulic cylinder repair process
- 1.Disassembly & Cleaning: Complete mechanical teardown with chemical degreasing to remove contaminated oil and debris.
- 2.Precision Measurement: Micrometer assessment of internal barrel roundness, wall scoring, and piston rod straightness.
- 3.Honing & Machining: Precision barrel honing, rod straightening or re-chroming, and custom gland fabrication as required.
- 4.High-Pressure Sealing: Assembly with premium industrial wiper seals, rod seals, piston rings, and wear bands.
- 5.Hydrostatic Pressure Testing: Full-stroke cycling on our test bench under working pressure to verify zero external or internal bypass.

Repair options and when each one is used
| Problem found | What we do | When it works |
|---|---|---|
| Worn or hardened seals | Reseal with a new seal kit | Rod and barrel within tolerance |
| Light rod scoring | Polish and rechrome the rod | Scoring under about 0.1 mm deep |
| Deep gouges or bent rod | Machine a new rod from induction hardened chrome bar | Rod cannot be restored within tolerance |
| Barrel wear or ovality | Hone the barrel, fit oversize wear bands | Wear under about 0.25 mm |
| Worn piston, gland or head bush | Machine a new piston, gland or bush in-house | Original part worn, damaged or slow to import |
Pistons, gland bushes and cylinder heads made in-house
When a piston, gland nut, head bush or end cap is worn, we do not wait for an import. Our lathe shop measures the old part or the mating bore and machines a new one from EN8, EN19 or phosphor bronze, then fits it with a matched seal kit.
Seals that last in UAE heat
Standard nitrile seals harden fast when oil runs above 85°C, which is common on UAE sites in summer. For hot or high duty cylinders we fit fluorocarbon (FKM, Viton) or hydrolysis resistant polyurethane seals.
Cylinders we repair
- Excavator boom, arm & bucket cylinders

Turnaround
Hydraulic cylinder reseal and repair: same day diagnosis, 24–48 hours turnaround, pressure tested to 350 bar.
Recent cylinder repair
A 280 mm bore excavator boom cylinder came in drifting and leaking at the gland. Sand had cut the wiper and scored the rod. We honed the barrel, restored the rod within OEM tolerance, fitted a new seal pack and held it at 350 bar for 30 minutes with zero bypass.
Hydraulic cylinder repair FAQs
How much does hydraulic cylinder repair cost in the UAE?
- It depends on bore, stroke and damage. A reseal is the lowest cost repair; rechroming, honing or a new rod add to it. ASAT gives a written quote after teardown, before any work.
Can a hydraulic cylinder be repaired instead of replaced?
- In most cases, yes. Seals, rods, glands, pistons and lightly worn barrels can all be restored. Replacement only makes sense when the barrel is cracked or worn past honing limits.
How long does a cylinder repair take?
- A reseal or standard repair usually takes 24 to 48 hours. Rechroming or a new machined rod takes longer, and we confirm the time after inspection.
Do you collect cylinders from site?
- Yes. We collect from Dubai, Sharjah, Abu Dhabi and the Northern Emirates, or remove the cylinder on site for you.
Do you repair telescopic tipper cylinders?
- Yes, single and multi stage telescopic cylinders for tippers, trailers and refuse trucks.
What should I send for a quote?
- Machine make and model, photos of the cylinder and any nameplate, and the bore, rod diameter and stroke if known.
