Standard Hydraulic Cylinders: A Guide to Shellppon's Eight Catalogue Series
News Details
Shellppon, the hydraulic cylinder manufacturer from Wuxi Shibang Machinery Manufacture Co., Ltd., produces a structured range of standard hydraulic cylinders for international OEM and plant buyers. Eight catalogue series cover double-acting differential cylinders built to European mill-type interfaces, metallurgical and heavy-duty equipment cylinders, engineering and vehicle cylinders, and rack-and-pinion swing cylinders that convert hydraulic pressure into rotary motion. Bore sizes across the range span 40 mm to 500 mm, and rated working pressures reach 25 MPa (250 bar) on the high-pressure mill type series.
This overview summarises each series with the specification ranges buyers ask about first — design, standard, pressure and bore — so procurement and engineering teams can shortlist models before requesting detailed dimension sheets or a custom quote.

Mill Type Hydraulic Cylinders: CDH and CGH Series
The CDH and CGH families are Shellppon's mill type hydraulic cylinder lines for high-force industrial equipment. CDH1/CGH1 cover piston diameters from 40 to 500 mm, with single-rod differential (=CD) and double-rod (=CG) versions, plus a wide choice of mounting styles: head and cap round flanges, foot mounts, trunnions and rod-end clevises. CDT3/CGT3 repeat this layout in compact bores from 40 to 200 mm for installations where space is tight.
CDH2/CGH2 (Series 1X) is the flagship of the family, with a rated pressure of 250 bar (25 MPa), piston diameters from 50 to 500 mm and stroke lengths up to 6 m. Mounting and connection dimensions follow ISO 6020-2 and ISO 6022 interfaces with DIN 24 333 and CETOP references, so the cylinders interchange with European-standard mill type equipment. Options include end-position cushioning, proximity switches and position measuring systems for automated lines.
Metallurgical Equipment Hydraulic Cylinders: Y-HG1 and JB/ZQ4395-86
Y-HG1 metallurgical equipment hydraulic cylinders have bottom mounting dimensions per ISO 6020-2, a rated pressure of 16 MPa and bores from 40 to 320 mm. Seal packages suit mineral oil, water-glycol and phosphate ester media, with media temperature ranges from −40 °C up to +120 °C depending on the seal — typical requirements in steel-plant environments.
The JB/ZQ4395-86 series heavy metallurgical cylinders work at up to 25 MPa in 13 bore sizes from 40 to 320 mm and eight mounting styles, with a working temperature range of −20 °C to +100 °C.
HSG Engineering Hydraulic Cylinders
HSG series engineering cylinders use a simple, robust construction with optional cushioning and three mounting styles: HSGL (external-thread rod end), HSGK (internal connection) and HSGF (flange). Rated working pressure is 10 MPa with bores from 40 to 250 mm. They power hydraulic functions on construction machinery, lifting and transport equipment and mining machinery.
DG Vehicle Hydraulic Cylinders
DG series double acting hydraulic cylinders serve mobile equipment. The double-acting single-piston-rod design with tail trunnion and eared-ring mounting covers working pressures of 8–16 MPa and bores from 40 to 320 mm on construction, transport and mining vehicles and similar machinery.
SB08 Swing Gear Cylinders: Rack-and-Pinion Rotary Actuation
SB08 swing gear cylinders turn hydraulic pressure into limited-angle rotation through an internal rack-and-pinion mechanism, working as hydraulic rotary actuators. The series carries a nominal pressure of 16 MPa, covers 14 piston diameters from 40 to 320 mm and reaches swing angles of up to 360°. Output torque scales with bore — from about 730 N·m on a 40 mm cylinder to roughly 225,700 N·m at 320 mm — and double-rack versions add a second rack piston for higher torque within the same bore. Single or double gear racks, foot or flange mounting, end-position cushioning options and seal packages for mineral oil, water-glycol (HFC) and phosphate-ester (HFD) fluids support duties from machine-tool clamping to heavy workpiece rotation. Installation and connection dimensions follow the JB/ZQ4713-86 standard.
Manufacturing and Quality Backing
All eight series are built at the company's plant in Wuxi, Jiangsu Province, which covers more than 7,000 m² and draws on more than 20 years of hydraulic cylinder manufacturing experience under an ISO 9001 quality management system. Alongside the standard catalogue, Shellppon engineers custom non-standard cylinders and complete hydraulic systems to customer drawings, serving metallurgy, shipbuilding, mining, aerospace and other heavy industries, with exports to Europe, the Americas and Southeast Asia.
