Industrial and Customized Hydraulic Cylinders

Custom & Industrial Hydraulic Cylinders — Built to Any Specification

SEIGO Machinery designs and manufactures custom and industrial hydraulic cylinders to any bore, stroke, pressure or tonnage. From heavy-duty hydraulic jacks and cement-plant process cylinders to special-shaped and one-off engineered designs, we work with no standard-catalog limits — send us a drawing, a sample, or just your application, and we build the cylinder to match.

Custom to Any Specification

Every cylinder is engineered to your exact requirements:

Bore & rod diameter — from precision bores to large-diameter press and mining cylinders.
Stroke length — short-stroke jacks through to long multi-stage telescopic designs.
Operating pressure — standard to high-pressure duty for drill rigs, roller presses and mills.
Configuration — single-acting, double-acting, and 2 / 3 / 4-section telescopic.
Mounting & rod ends — flange, clevis, trunnion, cross-tube and fully custom interfaces.
Materials & coatings — 42CrMo4 rods with chrome, HVOF or ceramic plating and application-specific seals.

Industries & Applications We Serve

We supply engineered hydraulic cylinders across mining, heavy industry and manufacturing:

Application / Type	What We Build
Hydraulic Jacks	Heavy-lift jacks — 800-tonne models and any custom tonnage, bore and stroke for mining, structural and equipment jacking.
Cement & Building-Materials Plants	Rotary kiln thrust roller, roller press, ATOX vertical grinding and high-pressure roller mill cylinders.
Telescopic & Multi-Stage	Single-acting, 3-section and 4-section telescopic cylinders for conveyors, tipping and lifting systems.
Demolition & Attachments	Hydro-shear cylinders and other heavy-duty attachment cylinders for excavators.
Drilling & Machine Tools	High-pressure drill-rig cylinders and vertical milling machine cylinders.
Fully Custom / Special-Shaped	Non-standard and special-duty cylinders built from your drawing, sample or application — any size, any scenario.

Why Choose SEIGO Cylinders?

Unlike generic suppliers, every SEIGO cylinder is engineered and built in-house:

In-house engineering — build from your drawing or reverse-engineer from a sample, with full dimensional and material control.
Material excellence — 42CrMo4 induction-hardened piston rods with chrome, HVOF or ceramic plating to suit the duty.
Superior sealing — NOK or Parker seal kits selected for heat, dust, high pressure or corrosion.
Rigorous testing — 100% pressure-tested at 1.5× operating pressure before shipment.
Warranty — backed by a 12-month / 2,000-hour warranty.

Whether you need a single engineered cylinder or a full production run, SEIGO turns your specification into a reliable, mining-grade hydraulic solution.
