Hydraulic cylinder
manufacturer
India.
Single acting, double acting and telescopic hydraulic cylinders custom built to your bore, stroke and pressure specification. Bore 40 to 600 mm, stroke up to 6,000 mm, working pressure to 350 bar. ISO 6020-2 and ISO 6022 mountings. Parker and NOK seals standard.
Custom-built
cylinders for
any application.
Fluidline hydraulic cylinders are designed and manufactured entirely at our Kundli facility. We do not stock generic cylinders and adapt them — every cylinder is engineered to your bore, stroke, working pressure, mounting arrangement and seal specification from the first conversation. That approach is what allows us to handle applications that catalogue suppliers cannot serve.
Our cylinder manufacturing line includes honing machines, CNC turning centres, internal grinding equipment, chrome plating facilities and a hydraulic test rig. Cylinder tubes are honed to Ra 0.4 µm finish, rods are hard chrome plated and ground to H6/g6 tolerance, and every cylinder is pressure tested at 1.5× working pressure before dispatch.
We manufacture single-acting, double-acting and telescopic cylinders for cranes, presses, unloading systems, grabs, machine tools and general industrial applications. Reverse engineering of obsolete or discontinued cylinders is a regular part of our work — send us a sample or a drawing and we will produce an equivalent or improved replacement.

Manufacturing
quality built into
every cylinder.
Honed Tube
Cylinder tubes are precision honed to Ra 0.4 µm bore finish. Consistent surface finish is the single most important factor in seal life — our honing process delivers it reliably across every bore size in our range.
Chrome-Plated Rod
Piston rods are hard chrome plated to a minimum 25 µm depth and ground to H6/g6 tolerance. Chrome plating provides corrosion resistance and the surface hardness needed to resist seal wear in extended service.
Replaceable Seals
All cylinders are designed with field-replaceable seal kits. Parker and NOK seals are stocked as standard. The seal cartridge is accessible without removing the cylinder from its mounting in most configurations.
ISO Mountings
We manufacture to ISO 6020-2 and ISO 6022 mounting standards as standard options. Custom mountings — clevis, trunnion, flange, foot — are available to customer drawing or sample. Replacement cylinders are dimensionally matched to the original.
Sensor Ready
End-of-stroke proximity sensors, reed switches and linear position transducers can be fitted at manufacture. Sensor pocket geometry and cable exit are designed into the cylinder body for a clean installation.
Pressure Tested
Every cylinder is pressure tested at 1.5× rated working pressure before dispatch. Test parameters, inspection results and dimensional check are documented in the certificate supplied with every unit.
Single acting,
double acting
& telescopic.
Single Acting
Hydraulic pressure extends the rod; retraction is by gravity, spring or external load. Simpler circuit, lower cost. Used in vertical lifting applications including press rams, jack cylinders and grab actuation where gravity return is reliable.
Request specificationDouble Acting
Hydraulic pressure controls both extension and retraction. Provides positive force in both directions — essential for applications requiring controlled retraction under load, including horizontal actuators, clamps and crane mechanisms.
Request specificationTelescopic
Two to five stage telescopic cylinders for applications requiring long stroke from a short collapsed length. Single and double acting variants. Used in tipping bodies, unloading systems and wherever mounting space is limited.

Why engineers
specify Fluidline cylinders.
True Custom Manufacturing
Every cylinder is built to your specification — not adapted from stock. Bore, stroke, pressure, mounting, seal brand and options are all defined at order stage. No compromise to suit a catalogue size.
Reverse Engineering Capability
We regularly produce replacement cylinders for obsolete and discontinued equipment. Send us the original cylinder or drawing and we will produce an equivalent or improved replacement, in stock or in as little as two weeks for urgent breakdown situations.
In-House Honing & Chrome
Honing and chrome plating are done in-house at our Kundli facility, not subcontracted. This gives us direct control over the two most critical quality parameters in cylinder manufacturing and eliminates the delays of external processing.
