Hydraulic Cylinders

As a manufacturer of hydraulic cylinders, we specialize in the industrial tie-rod design – both the standard NFPA interchangeable tie-rod design and the custom design. We offer our hydraulic cylinders in the medium-duty pressure range (pressure-rated per bore size) and the high-pressure range.

High Pressure Hydraulic Cylinders – Series HP

  • 3,000 PSI nominal pressure rating
  • NFPA Tie Rod Design 1-1/2″ to 12″ bore
  • Standard Steel Construction
  • SAE660 bronze wetted rod bearing
  • Polyurethane rod seal, piston seals and tube O-Rings for standard petroleum-based fluids
  • Chrome plated, Case hardened piston rods
  • High Pressure Hydraulic Catalog

Additional Product Info

In designing the HP Series high pressure hydraulic cylinders, Lehigh has developed a product that is rugged, reliable and the perfect balance of design, material and precision workmanship. HP cylinders can be designed for spring extend and retract, configured for all types of hydraulic fluids including water and with many sensing options including tie rod mounted limit switches up to 4″ bore.

Other Seal Options:
Viton – for high temperature and some fire-proof fluids
EPR – (Ethylene Propylene Rubber) Some fire proof fluids, some aircraft fluids, automotive brake fluid
Nitrile – vegetable oils, water/glycol, water

Seal options are available for low friction applications, servo applications, fluid pump applications, redundant rod seals with gland drain.

Stainless Steel High-Pressure Hydraulic Cylinders – Series LSSW

  • NFPA tie rod design 1-1/2″ through 8″ bore
  • All-Stainless Steel Construction
  • 3000 PSI rated – consult factory for pressure rating above 8″ bore
  • Stainless steel bearing housing with nylon bearing liner
  • 17-4PH chrome plated piston rod
  • Polyurethane seals for petroleum based fluids
  • Stainless Steel High Pressure Hydraulic Catalog

Additional Product Info

The LSSW® Series High-Pressure Hydraulic Stainless Steel Cylinders are designed to achieve long life and consistent performance in the most challenging conditions including submerged operation, chemical exposure, Clean Room Operation and in FDA and USDA approved equipment.

Options: all 316 SS construction, water hydraulic, high temp seals, seals for non-petroleum based fluid, sub-sea applications and tie rod mounted limit switches up to 4″ bore.

Standard Medium Pressure Hydraulic Cylinder – JHDH Series

  • Brass Tube and Standard Steel Construction
  • NFPA Tie Rod Design 1-1/2″ to 6″ bore
  • Polyurethane piston, rod seals, rod wiper and tube o-rings
  • 5/8″ – 3/1/2″ chrome plated piston rod – 100,000 PSI min yield
  • Sintered bronze/SAE660 bearing
  • Configurable with tie rod mounted limit switches
  • Medium Duty Hydraulic Catalog

Additional Product Info

The JHDH Series offers pressure ratings from 2000 PSI with the 1″ bore to 600 PSI for the 6″ bore (see catalog for bore v. maximum working pressure rating). The construction of the actuators in this series gives the system designer the ability to more closely and cost effectively match the actuator to the circuit pressure rather than opting for the 3000 PSI rated high pressure hydraulic series.

Stainless Steel Medium Pressure Hydraulic Cylinder – LSSE Series

  • All Stainless Steel construction
  • NFPA Tie Rod Design 1-1/2″ to 6″ bore
  • Rulon rod bearing in a stainless bearing housing, front removable without cylinder disassembly
  • Nitrile piston seals with Teflon backup
  • Polyurethane rod seal, wiper and tube O-rings
  • 17-4PH stainless steel chrome plated piston rod
  • Medium Duty Hydraulic Catalog

Additional Product Info

The all stainless LSSE® series are rated from 1500 PSI at 1″ bore and go to 600 PSI at 6″ bore (see catalog for bore v. maximum working pressure rating). As with the JHDH series, the system designer can add tie rod mounted limit switches as an economical alternative to proximity sensors or linear diplacement transducers.


  • BTL Micropulse tranducers
  • Strokemaster cylinder position sensors
