Custom Hydraulic Cylinders from Drawing or Sample — MOQ 1 Piece, OEM/ODM

Hengshui Machinery's core competency is non-standard custom hydraulic cylinder manufacturing. We manufacture from customer engineering drawings (DXF, DWG, STEP, IGES, PDF), physical samples, or interchangeable-replacement specifications — with no minimum order quantity, full NDA protection, and a 24-hour quotation target. Every cylinder is built to your specific bore, stroke, pressure rating, seal compound, mounting style, port configuration, and surface treatment.

Our engineering team provides design support throughout the process: bore sizing and rod diameter verification, pressure vessel wall thickness calculation, seal compound recommendation, rod chrome plating thickness specification, and mounting geometry review. For OEM customers with regular production volumes, we establish dedicated material and component stock programmes to reduce lead times. For new applications, we strongly recommend a prototype phase — our minimum prototype quantity is 1 unit, manufactured on full production tooling and fully representative for testing and validation purposes.

Parameter Specification
Bore range Ø20 mm – Ø800 mm (any size to drawing)
Stroke range 10 mm – 8,000 mm single-stage; greater with telescopic design
Pressure range Up to 350 bar standard; 500 bar custom; 700 bar special project
Seal options NBR, FKM, PU, PTFE, EPDM, HNBR — to application requirement
Rod options Chrome, stainless, nickel, ceramic coating, hollow — to drawing
Mounting options Any style to DIN, ISO, NFPA, JIS, GOST, or bespoke drawing
Documentation EN 10204 3.1/3.2 material certs, pressure test cert, dimensional report
Certifications ISO 9001:2015 standard; CE, BV, ABS, DNV, GL marine optional

Custom Cylinder Capability Highlights

From your engineering drawing

Supply DXF, DWG, STEP, IGES, or PDF drawings. We review, confirm feasibility, calculate critical dimensions, and provide quotation within 24 hours. NDA signed before any technical exchange.

From a physical sample

Supply the cylinder you wish to replicate. Our engineers 3D-scan or manually measure all dimensions, reverse-engineer the specification, and produce an identical or improved-specification replacement.

Interchangeable replacement

If you have a cylinder from Parker, Bosch Rexroth, Hydraulics International, SMC Cylinders, or another OEM that needs a like-for-like or upgraded replacement, we manufacture an interchangeable alternative at competitive factory-direct pricing.

Single-piece prototype

We manufacture prototype quantities from 1 unit on full production processes — same materials, same equipment, same quality procedures as series production. Fully representative for your testing and validation programme.

Series production (10–5,000+ units)

Once your prototype is approved, we transition to series production with dedicated stock programmes, call-off schedules, and competitive unit pricing at volume.

OEM private label / white label

We manufacture without any Hengshui markings. Your part number, nameplate data, and packaging can be applied. Full confidentiality — your customers will not know the manufacturing source.

Design assistance service

If you do not have a complete drawing, provide your application requirements (load, speed, stroke, space envelope, fluid, environment) and our engineers will design an appropriate cylinder and produce outline drawings for your approval before manufacturing.
