Threaded / Ring Retained Hydraulic Cylinders

Welded / Threaded Hydraulic Cylinder

RamRod is a leader in the design and manufacture of welded construction cylinders, utilizing internal threaded head, external threaded cap, or internal thread ring construction.

RamRod supplies custom welded and threaded-type hydraulic cylinders for a wide range of applications.

Whether we are manufacturing our own proven designs, or using RamRod’s advanced manufacturing capabilities to efficiently produce our customer’s proprietary designs, our mission is always to ensure our customers are receiving high-quality, cost effective hydraulic cylinders that are both, safe and reliable.

Bolted On Head Hydraulics

Bolted-Head Hydraulic Cylinder

RamRod excels in designing and manufacturing custom hydraulic cylinders that are utilized in rough service environments.

RamRod is a leading supplier of bolt-on head style hydraulic cylinders for these rugged applications.

RamRod’s bolt-on head designs allow for higher pressure capabilities, ease of service, while at the same time, retaining a relatively compact closed length.

RamRod bolted-head construction cylinders can be found on equipment used in industries, such as, excavating, mining, forestry, metal scrap handling and other extreme duty applications.

Integrated Valve Solutions

Jack Leg Cylinder

RamRod custom designs and manufactures Jack leg cylinders to lift and level equipment, such as, portable crushing plants, recycling plants, cranes, aerial lifts, fire trucks and many others.

RamRod jack legs feature pin arrangements for safe position locking; swivel action foot designs for lifting on uneven terrain, mounting plates that are height adjustable for customer specific applications, anti-drift features and unique foot attachments that best meet our customer’s specification.

There are no exposed rods to corrode, dent, or scratch. There are no external transfer tubes to bend. RamRod builds in the quality.

Integrated Valve Solutions

Cylinder with Integral Valve Block

RamRod designs and manufactures a wide range of hydraulic cylinders with integral valve solutions.

RamRod custom designs valve blocks that can incorporate a variety of valve types, including: positioning, pressure sensing, load holding, proportional, or sequencing.

RamRod quality cylinders with integral valve solutions simplify the hydraulic system on most equipment and offer reduced installation costs.

Integrated Valve Solutions

Cylinder with Linear Position Sensor

Today more and more OEMs are designing their equipment with enhanced automation to achieve greater operating efficiencies and reduced costs.

As a result, the need for cylinders with integrated feedback sensors has grown rapidly.RamRod is a leading designer and manufacturer of cylinders with integral linear transducers.

These provide the necessary feedback on cylinder rod extend position for critical automated hydraulic functions.

Cylinder designs with external position sensors are also available.

Nitrogen Charged Accumulator

RamRod designs and manufactures a variety of quality custom accumulator types.

Standard piston accumulators: These use hydraulic oil actuating a piston against nitrogen charged internal surface area, and are used in a hydraulic system to dampen pressure spikes.

Cylinders with internal accumulators: This type is also nitrogen charged and uses standard hydraulic oil. The cylinder can be cycled and operated as in raising and lowering an axle, and has an internal accumulator piston used to dampen road vibration induced pressure spikes. A typical example would be an auxiliary axle on a cement or dump truck.

Nitrogen charged struts: These struts use specialized automotive fluid to act as an internally dampened spring on large off-highway truck suspensions. The nitrogen and oil are an emulsion and are separated by an orificed piston that acts to dampen the suspension.



RamRod’s design and manufacturing capabilities allow us to address a broad spectrum of hydraulic cylinder applications, which include:

  • Single-acting
  • Double-acting
  • Non-tie rod
