Underground LHD Lift Cylinder
The core lift actuator of underground Load-Haul-Dump machines. Mounted between the vehicle frame and bucket arm, it raises full ore loads and works with the tilt cylinder to complete each load–haul–dump cycle in mines and tunnel mucking — where shock loads, abrasive dust and confined service access punish weak seals and thin rods.
End-Cushioned Buffer Cylinder
Cushioning at head and base decelerates the piston at stroke ends — reducing shock, noise and seal wear on boom, arm and bucket circuits.
Details
Reversible Plough Turnover Cylinder
Double-acting design delivers precise 180° rotation of the plough frame, coordinated with the tractor pump and control valve.
Details
4-Stage Telescopic Cylinder
Four nested sleeves provide a working stroke far longer than the retracted length, then retract smoothly in sequence for compact storage.
Details
Rotary Actuator HCR801
Converts hydraulic power into controlled swing of the platform's working arm for stable positioning at different angles.
DetailsWelded, tie-rod-free and telescopic hydraulic cylinders for excavators, cranes, loaders, forklifts, aerial platforms, mining and farm machinery — single- or double-acting, metric or imperial.
All Hydraulic Cylinders
T3A Counterbalance Valve Block MPM-HCVB3A
Integrates counterbalance, check and safety valves in one manifold to stop uncontrolled load movement on cranes and lifts — and to lock the load even if a hydraulic line ruptures. Pressure-adaptive flow keeps motion smooth, with a response time under 15 ms and strong contamination resistance.
T13A Flow Control Valve Block
Regulates oil flow to set actuator speed precisely for smooth, repeatable machine motion.
Details
T2A Relief Valve Block
Relief valve and oil channels in one block to stabilise system pressure and protect components from overpressure.
Details
Hydraulic Station Valve Block
Multiple valve functions combined to control direction, pressure and flow from the hydraulic power unit.
Details
Differential Lock Solenoid Valve
Electromagnetic spool control locks and unlocks the differential to improve traction on difficult terrain.
DetailsCustom hydraulic manifolds machined from your circuit diagram: counterbalance, relief, flow control, solenoid and copper speed-control blocks for mobile and industrial hydraulics.
All Hydraulic Manifolds
Hydraulic Cylinder Head MPM-HCHD11
The end-closure assembly that seals the barrel into a pressure chamber, guides and supports the piston rod, and houses the sealing system — step seals and guide bushings — while carrying working pressure and mechanical loads. Concentricity between rod bore and barrel spigot is what decides seal life, so it is held on our CNC lathes.
Hydraulic Cylinder Piston
Precisely matched to the barrel bore, with seal grooves on the periphery and a secure rod connection.
Details
Integrated Cylinder Barrel
Barrel and flange CNC-machined as one piece — fewer joints, fewer leak paths, better structural stability.
Details
Hydraulic Spherical Bearing
High-strength alloy with self-lubricating liners for heavy, oscillating loads at cylinder eye ends.
Details
Hydraulic Cylinder Nut
Forged, heat-treated alloy steel with ISO 6H thread precision and anti-loosening lock design.
DetailsReplacement and OEM cylinder components for cylinder builders and repair shops: heads, pistons, nuts, flanges, bases, bushings, barrels and spherical bearings.
All Hydraulic Parts
Milling Tool Holder MPM-CTH400
Also called an ER tool handle or milling chuck arbor: the link between the machine spindle and the cutting tool, made up of the holder body, spring collet and clamping nut. Runout at this interface shows up directly on surface finish and tool life — which is why we machine the tooling we also use on our own cylinder parts.
ER Collet MPM-EC0070
For boring, milling, drilling, tapping, grinding and engraving — clamps end mills, drills and taps.
Details
Retention Knob DIN 69872
Draws the tool holder tight to the spindle for stability and precision; JIS B6339 version also available.
Details
Side Lock Tool Holder
Set-screw clamping on the shank flat for rigid holding of end mills in heavy cutting.
Details
Pneumatic Hydraulic Vise
Combines air and hydraulic force for fast, repeatable clamping of precision parts on mills and drills.
DetailsCNC machine tool accessories: tool holders, ER collets and nuts, DIN / JIS retention knobs and precision vises for machining centres and milling machines.
All CNC ToolsHydraulic Cylinders by Machine Type
Every machine loads a cylinder differently — side loads on a loader boom, shock on a mining bucket, long strokes on a crane. Start from your equipment type to see cylinders engineered for that duty cycle.
Excavator Cylinder
Boom, arm & bucket cylinders, incl. end-cushioned designs.
Truck Crane Cylinder
Multi-stage telescopic and luffing cylinders for long strokes.
Loader Cylinder
Lift, tilt and steering cylinders for wheel and LHD loaders.
Forklift Cylinder
Steering, lift and tilt cylinders for material handling.
Aerial Work Platform Cylinder
Lift, jib and rotary actuators for AWP stability.
Mining Equipment Cylinder
Underground LHD lift and tilt cylinders for harsh duty.
Agricultural Machinery Cylinder
Plough turnover and stepless width-adjustment cylinders.
Other Cylinders
Sanitation, refuse-truck lifting and locking, custom builds.
Machined in Qingdao. Trusted by 50+ Equipment Brands.
Founded in 2006, Qingdao Micro Precision Machinery Co., Ltd. specialises in hydraulic cylinders, hydraulic components, hydraulic manifold valve blocks and CNC-machined parts. Nearly two decades of machining for construction, agricultural, mining and material-handling equipment has taught us where hydraulic parts actually fail — rod finish, seal-groove geometry, thread fit and weld integrity — and that is where our process control is concentrated.
An in-house R&D and design team, high-precision CNC equipment and a structured quality-control system let us keep quality consistent from sample to repeat order, the reason both new and long-term customers keep coming back.

Inside Our Qingdao Factory
What We Control In-House
Buyers sourcing hydraulic cylinders from overseas mostly worry about three things: will it fit, will it seal, and will the next batch be the same. Keeping the critical operations under one roof is how we answer all three.

|---|---|
| Machining | CNC turning, milling and grinding of heads, pistons, bases, flanges and manifold blocks |
| Standards | Metric & imperial threads; ISO 6H nut threads; DIN 69872 / JIS B6339 tooling references |
| Quality | Dimensional checks against confirmed drawings and final inspection before packing |
| Logistics | Export packaging; sea, air or express courier with tracking provided |
Engineered for Extreme Working Conditions
From muddy job sites to underground mines and machining centres, our components are specified around the real load, stroke and environment of each machine.
01Construction Excavators & Earthmoving
Boom, arm and bucket cylinders face constant shock and abrasive contamination. End-cushioned designs and robust rod sealing protect the machine and extend overhaul intervals.
- Boom / arm / bucket
- End cushioning
- OEM replacement
02Loaders Backhoe & Wheel Loaders
Backhoe loaders combine digging and loading for municipal works, rural construction and small projects — demanding cylinders that handle mixed duty cycles reliably.
- Lift & tilt
- Steering
- Buffer cylinders
03Material Handling Forklifts & Warehousing
Forklifts load, unload, stack and shuttle goods all shift long. Smooth steering and lift cylinders reduce operator fatigue and load sway.
- Steering cylinders
- Lift & tilt
- High cycle counts
04Agriculture Harvesters, Ploughs & Tractors
Combine harvesters integrate harvesting, threshing and cleaning; reversible ploughs need precise turnover and width control. Seasonal peak loads leave no room for downtime.
- Plough turnover
- Width adjustment
- Harvester header
05CNC Machining Machining Centres & Mills
Tool holders, collets, retention knobs and vises that keep spindle-to-tool runout low — the same tooling discipline we apply to our own hydraulic parts.
- ER tool holders
- Retention knobs
- Precision vises

The questions overseas purchasing and engineering teams ask us most before their first order.
Ask Our EngineersWhat information do you need to quote a custom hydraulic cylinder?
Send bore diameter, rod diameter, stroke, retracted (pin-to-pin) length, working pressure, single- or double-acting design, mounting type at both ends, port size and thread standard, operating environment and estimated annual quantity. A drawing, a sample or a photo of the original nameplate shortens the quotation process.
Can you reproduce an OEM replacement cylinder from a sample?
Yes. Our engineers measure the sample, prepare a technical drawing and send it for your confirmation before machining starts, so interchangeability is agreed in writing before production.
Which standards do your parts and tooling follow?
We machine to the customer drawing in metric or imperial units. Typical references include ISO 6H thread tolerance for hydraulic cylinder nuts, DIN 69872 and JIS B6339 for CNC retention knobs, and ER collet systems for milling tool holders.
Do you supply hydraulic cylinder components separately?
Yes. We supply cylinder heads, pistons, nuts, flanges, bases, integrated barrels, bushings and spherical bearings, as well as hydraulic valve blocks, for cylinder builders and repair workshops.
