We Stand Up To The Competition!

Learn more about Duramaster who manufacturers a top of the line pneumatic cylinder actuator and what stands us apart from our competitors tie rod cylinders.

When you are considering the purchase of a tie rod cylinder for industrial factory applications, you have to be certain it will perform optimally. Whether for automotive, aeronautics, climate control, robotics or other purposes, the cylinder you choose must work consistently and execute limited functions flawlessly. It also needs to have a long service life, be easy to remove and be quickly disassembled for repair and maintenance.

Picking a tie rod cylinder that will go the distance is crucial. The table below shows you how Duramaster tie rod cylinders are engineered for precision and durability. And it indicates, without naming names, where other manufacturers might cut corners.

The good news is that customers can obtain a superior product like the Duramaster tie rod cylinder and obtain high quality at low cost.

In exacting conditions and under tremendous force, failure is simply not an option. You need precision-machined parts. Misalignments, seal breaks and speed variations are the common results from using inferior tie rod cylinders. Don’t risk poor performance in your cylinder. Instead, buy a tie rod cylinder that functions smoothly, operates quietly and is a model of stability.

We are very focused on providing customer service as top notch as our cylinders. The engineers and visionaries at Greenco/Duramaster are available to you for advice and support pre and post purchase. Another aspect of our customer service is that we can arrange for same day shipments of your new tie rod cylinder, if you need the unit in a rush.

NFPA Tie Rod Cylinders from Duramaster – They Go The Distance

Duramaster NFPA Tie Rod Cylinders

Us Them
Long style 660 bronze bushing provides maximum wear resistance for increased durability and lowest friction. Some other manufacturers use ductile iron or even plastic bushings.
Graphite impregnated wear bands on the piston are extra wide for added support. Some manufacturers do not even include wear bands.
Floating cushions reduce the speed of the piston as it approaches the end of stroke, but they do not affect the speed of the piston in the opposite direction. Some other manufacturers use cushions that affect the speed in both directions, and some do not even offer cushions.
Headcaps are machined from 6061-T6 aluminum for high strength and low weight. Then they are black anodized to resist corrosion and oxidation. Some manufacturers use die cast heads, which can have low strength issues, and porosity problems.
Bushing retainer plate is removable with standard allen wrenches (hex keys). This allows the bushing to be replaced easily, without disassembling the cylinder. Some manufacturers retain their bushing with snap rings, or do not have removable bushings at all.
Our Full Duramount™ series provides internal tie rod nuts for maximum space savings and interchangeability of mounting styles. Other manufacturers have exposed tie rod nuts which can create space problems, and can prevent interchanging mounts.

Duramaster Tie Rod Cylinders Key Features and Options

Rod Bushing – Bronze Bearing. Long style 660 bronze bushing provides maximum wear resistance for increased durability and lowest friction.

Cylinder Tube – 35,000-PSI aluminum alloy. I.D. of tube is hard anodic coated. 60 RC on I.D.

Head Caps & End Caps - 6061-T6 aluminum alloy extrusion and black anodized for corrosion resistance. Head caps are machined from 6061-T6 aluminum for high strength and low weight. Then they are black anodized to resist corrosion and oxidation.

Bushing Retainer Plate – Anodized aluminum. Removable with standard allen wrenches (hex keys). This allows the bushing to be replaced easily, without disassembling the cylinder.

Piston - 6061-T6 aluminum alloy.

Piston Rod - C1050 steel alloy 100,000-psi minimum yield. Ground & polished with a hard chrome finish 68-70 RC. Stainless Steel Available.

Tie Rods & Nuts - Stress-proof steel. Plated. Recessed Nuts Plated. Stainless Steel Available.

Wear Band - Specially compounded nylon with high strength reinforced materials and impregnated with a special lubricant. Graphite impregnated wear bands on the piston are extra wide for added support.

Tube End Seals – Reinforced fiber material.

Piston Seals – Lip type, wear-resistant nitrile.

Rod Wiper - Double lip wiper/seal ring - high quality polyurethane.

Cushion Seals - Floating nitrile - resists external misalignment. Floating cushions reduce the speed of the piston as it approaches the end of stroke, but they do not affect the speed of the piston in the opposite direction.


Unless otherwise specified, ALL our cylinders will feature EXPOSED Nuts in Rear and Button Head Screws in the Front. Our Full Duramount™ series provides recessed, internal tie rod nuts for maximum space savings and interchangeability of mounting styles.
