Series B is our standard heavy duty hydraulic cylinder. The bolt on head design and all welded construction results in a simple and strong cylinder which is easy to assemble and disassemble. These cylinders are a reliable choice for industrial, marine or mobile equipment applications.

Double Rod Cylinders
All Series B cylinders are available in a double rod design. Double rods are used when the cylinder speed must be the same in both directions. This is beneficial when the cylinder speed is used to meter the amount of material or work flow that is moved with each cycle. Double rod cylinders can also be used to actuate a second function with the other rod.

Back to Back Cylinders
All Series B cylinders are available in a back to back design. Back to back cylinders are useful when loads must be moved in different stages. They are also useful when different sizes of loads must all reach the same end point. With up to four cylinders combined, loads may be moved in four stages with one cylinder installation.

Our Series TM cylinders, with suitable electronics, can monitor the position and velocity of the piston. It is based on our popular Series B cylinder with provision for mounting an LVDT (Linear Velocity Displacement Transducer) and magnet from Temposonic, Balluff, or any other manufacturer.

The transducer assembly is mounted into the blind end of the cylinder. The magnet is housed in a stainless steel piston nut and the probe is inserted into a blind hole in the rod. The rod is drilled from one end only, which makes for a much stronger rod end than one that is drilled from both ends. A male thread is standard for the rod end. Therefore, any size and style of accessory with female threads is available. Female threads in the rod end can be accommodated, but the rod extension must be increased by the depth of the threads.

The transducer head is safely protected inside a sealed housing. Since the back end of the cylinder must be clear to withdraw the probe, the available mounting styles are front and mid trunnion, front and rear flange and foot mount.

The pressure rating is 3000 psi operating and 5000 psi non-shock and fixed cushions at both ends of the cylinder are standard with series TM.

Options are avaliable to mount a variety of servo or proportional valves on the cylinder.

Our Series EX are high strength cylinders designed for high pressures, high flows and rugged environments. They are particularly suited to demanding industrial and mobile equipment applications.

Our Series TH is designed specifically for hydraulic thumb applications on track mounted and wheeled excavators. Heavy duty construction, a guarded transfer hose and oversize spherical bearing mounts at both ends all contribute to long life and trouble free service in this rugged working environment.

Our Series IT hydraulic cylinder is a simple and economical design. With a 2,500 psi working pressure and a 3,500 psi non-shock load pressure we have not compromised on the quality, yet have made it an affordable and reliable alternative as opposed to using our more rugged bolted on head gland construction style of hydraulic cylinder.

To strengthen the open end of the cylinder, a thick ring is welded to the barrel to carry the internal thread and port. Both ports are machined into the cylinder barrel itself, which means localized weld distortion and the stress concentrations that arise from welding half couplings for ports are eliminated. The internal threads that hold the head gland will not corrode since they are constantly submersed in oil. The piston is securely threaded and adhesive bonded to the rod. To accommodate our customers wide range of needs, we manufacture the barrel and cylinder rod to order on every hydraulic cylinder order to provide the exact strokes and pin to pin dimensions that are required. A variety of mounting accessories can be installed onto the cylinder to suit virtually any application. Other rod materials and mounting styles, such as trunnion and flange mount, are available on request.

Our Series MIT is our Miniature Internal Thread hydraulic cylinder. It's a welded construction cylinder with an internal threaded gland rated for 3,000 psi working pressure and 4,000 psi non-shock pressure.

To accommodate our customers wide range of requirements, we manufacture the barrel and rod to order for every hydraulic cylinder to provide the exact stroke and pin to pin dimensions as required. Various combinations of mounting accessories can also be installed onto the cylinder to suit most applications. Other rod materials and mounting styles as needed, such as trunnion and flange mount, areavailable on request.

All MIT cylinders have National Pipe Thread (NPT) ports. The blind end port is always placed at 90° to the center line of a fixed pin axis. The clevis style of blind end always has two ports, one in line with the rear port and one that is at 90° to this port.

Whenever possible, spherical bearings mounts should be used on both ends of the cylinders. This will reduce any mounting misalignment and side loading that may be introduced into the cylinder. This type of loading should definitely be avoided on cylinders with small diameter rods such as used on this series.

Our Series SIT is a Single acting Internal Thread displacement cylinder. With a pressure rating of 2500 psi working and 3500 psi non-shock, the pressure acts on the rod to create an extend force that is equal to that of the pressure times the rod area. An external force, generally gravity, retracts the rod once the oil is allowed to leave the cylinder. The piston supports and guides the rod.

The cylinder is well sealed at the rod end which will keep the inside of the cylinder barrel from becoming contaminated. The advantage of this design is that the inside of the barrel is not exposed to atmosphere and the rod is always immersed in oil when retracted which will keep the rod from corroding. Also, only one hydraulic pressure line is required in order to operate the cylinder, thus simplifying the hose routing.

Since pressure acts on the area of the rod and not on the piston area, it is necessary to use a larger bore than a non-displacement type of cylinder design to exert the same force.

There is a 1/16" NPT plug at the rod end of the cylinder barrel which is provided to bleed air out of the cylinder during installation. This must be done in order to prevent the cylinder from becoming spongy due to the compressibility of the air trapped inside the cylinder.

Our Series LB is a large bore double acting cylinder. They have a 3,000 psi working pressure rating and a 4,000 psi non-shock pressure rating. They are designed for a multitude of applications where a large force is required in both the push and pull directions.

Our Series J cylinders are designed for high tonnage jacking applications. Rated to operate up to 10,000 psi, they feature quality construction in a compact package. They are a double acting cylinder, therefore they can be used to push and also pull a load if needed.

Pancake Style Cylinder
The pancake cylinders are meant for short stroke straight lift applications. They are a single acting cylinder operating at 10,000 psi. and would generally be operated by a manual pump. The rod is inserted directly into the barrel without any head gland holding it in place. As such the operator must be careful not to pump the rod out of the barrel. There is a line machined into the rod to mark the safe limit of the extension. A carrying handle is standard. Strokes are either 1lt or 2lt only. These cylinders are ideal for construction work, machinery lifts and emergency rescue work.

Our Series S cylinders are a snap ring style of cylinder, that is the head gland is held in place with a snap ring. They are rated for 2,000 psi operating pressure, and have a 3,500 non-shock pressure rating.

A telescopic cylinder is essentially a series of cylinders (called stages) nesting inside one another. It is normally used where space is a constraint.

Each stage is the rod of the larger stage and the barrel of that stage. e.g. A 3-stage cylinder is 3 stages or rods that move in and out. It consists of the barrel (the largest tube) followed by the first stage and then the second stage and finally the smallest stage (called the rod).

Single Acting
A S/A telescopic is essentially a displacement cylinder. It extends by hydraulic power and retracts by gravity or any external force. The oil pressure acts on the outside diameter of the various rods. When retracted, the various stages are immersed in oil, thus protecting them from rusting. These cylinders do not leak unless the rod seals are damaged. The port is located at the barrel end and a bleed port at the rod. The cylinder is sealed at the rod end.

Double Acting
D/A telescopic is powered both ways. Oil acts on the bore area to extend and on the annulus area between the bore and rod to retract. The extend force is typically 5 times the retract force. Because of this intensification, it is critical that the retract port is not restricted. D/A cylinders will slowly drift due to seal leakage; the leakage rate is dependent on the surface finishes of the cast iron piston seals and the barrel surface. The ports are located at the rod end. The first stage extends first, when extending the cylinder; on retracting, the rod stage retracts first.

The Series SS is designed for the marine and food industries for maximum 3,000 psi working pressure. All exposed surfaces are SS316 for maximum corrosive resistance.

The rod is SS316 with 0.002” thick hard chrome. The hard chrome is to provide a hard surface for the rod seal and wiper to ride on.

The standard attachments for the rod end are metric, maintenance -free spherical bushing with male thread. The rod has a female thread, because the thread is the weakest link and if it breaks, it is considerably cheaper to replace the spherical rod end than purchasing a new rod. At the blind end, from 5/8 (20mm) diameter and smaller, the spherical bushing is threaded on and from 3/4 (25mm) and larger it is welded.

A stainless steel jam nut is used to lock the spherical bushing and to provide a small adjustments in length.

The spherical bushing reduces bucking of the rod, but is it the responsibility of the customer to select the proper rode size, stop tube, etc to avoid buckling.
