Tie Rod Hydraulic Cylinders
Tie rod hydraulic cylinders use high-strength threaded steel rods to hold the two end caps to the cylinder barrel. This method of construction is most often seen in industrial factory applications. Small bore cylinders usually have 4 tie rods, while large bore cylinders may require as many as 16 or 20 tie rods in order to retain the end caps under the tremendous forces produced.
The National Fluid Power Association (NFPA) has standardized the dimensions of hydraulic tie rod cylinders. This enables cylinders from different manufacturers to interchange within the same mountings. Tie rod style cylinders can be completely disassembled for service and repair.
We can provide you with standard and custom-made hydraulic cylinders, including tie rod hydraulic cylinders, to suit your specific application, requirements and operating parameters; just complete our Bespoke Cylinder Design Form and one of our team will get back to you.
Made here in the UK, our Series HOL-T tie-rod hydraulic cylinders conform to the requirements of ISO 6020/2 – 1991, DIN 24554.
Their heavy-duty construction, wide range of mounting styles and customisable design features makes them suitable for a wide range of applications. All designs are created utilizing 3D design software, which can be exported to enable you to import the cylinder or actuator model directly into your own machine design. Component parts are manufactured using latest CNC machinery; ensuring part interchangability and supporting responsive lead times.
These tie-rod cylinders are designed with generous internal bearing lengths, using high quality materials in their construction together with proven seal types and a choice of sealing systems and materials. End of stroke cushioning is available at either or both ends of stroke. All of our tie-rod hydraulic cylinders can also be supplied with: internal full displacement positional transducers, end of stroke sensors and control valve packages - having valves built directly into the cylinder endcap or manifolded onto the cylinder.
All cylinders are tested to 1.5 x the designed working pressure and are supplied as standard in satin black enamel paint, but can be supplied with external surfaces plated or shotblasted and marine specification painted.
Key features include: 160 bar working pressure, 210 bar peak; suitable for mineral oils, soluble oils, HWB fluids, and ether based fluids; operational speeds of 500mm/sec subject to fluid type and pressure; temperature range of -20C to + 80C with standard seals, and -20C to + 150C within viton seals.
