Rexroth Hydraulic Cylinders

Need a direct replacement for Rexroth or Bosch hydraulic cylinders? Look no further than Gorilla Spares. The products we carry are tested to OEM specifications, and we can get you up and running as quickly as possible.

Gorilla Spares carries aftermarket replacement (spare) hydraulic, electrical, electronic, and robotic parts for industrial, agricultural and aerospace equipment.

We are not a manufacturer; we do not repair equipment; we have no brand affiliations, manufacturer ties or distribution agreements. We are simply a bridge between the best vendors in the business and end-users who are looking for their products online but have been unable to find them via traditional business-to-business sales and distribution channels.

Rexroth, a Bosch company, is known for its high-quality hydraulic products, such as cylinders, pumps, valves and motors, that serve a broad range of demanding industrial environments and applications, Gorilla Spares provides excellent direct replacements for Rexroth and Bosch mill-type and tie-rod hydraulic cylinders and hydraulic valves.

Reach out to us when you need a direct replacement part or a solution for a hard-to-find, out-of-production or obsolete part. We can help you find spare parts, even if you don’t see them on our website.

Hydraulic Cylinder Terminology

The Gorilla Spares team has provided this glossary of terms for those new to hydraulics, and hydraulic cylinders in particular, to help you understand their importance.

• Barrel – This is the cylindrical body of the cylinder. It guides the piston, provides a sealing surface for the piston seal, and holds cylinder pressure.
• Base or Cap – This refers to the end closure that completely covers the bore area.
• Bore– This is the inside diameter of the cylinder tube. It determines the total power of the cylinder. The larger the bore, the more it can lift or push.
• Cushion– A mechanical device that is fitted into a hydraulic cylinder to close off the flow of fluid to slow it down before it reaches the end of the stroke.
• Cylinder, Double-acting – Double-acting cylinders can apply force and motion in either direction.
• Cylinder, Single-acting – Single-acting cylinders can apply force in one direction only.
• Cylinder, Telescoping – This cylinder is constructed like a telescope and consist of a series of tubular rods called “sleeves.” The sleeves decrease in size sequentially and are nested inside each other.
• Drift – Internal leakage in the cylinder across the piston causes fluid to physically move from one side of the piston to the other. This creates an uneven balance that results in cylinder movement or “drift”.
• Head Gland (Stuffing Box)– The head gland or stuffing box serves several purposes. It retains the static and dynamic seals at the head end of the cylinder, it seals off the oil at the end of the cylinder, it is the support or guide for the rod, and it keeps the piston from falling out of the barrel.
• Piston – The main function of the piston is to separate the pressure zones inside the cylinder barrel. The difference in pressure between the two sides of the piston causes the cylinder to extend and retract.
• Piston Rod – The piston rod is also known as the cylinder shaft or ram. It is the round device that moves in and out of the cylinder. It can be solid or hollow and is usually plated or heat-treated to provide better wear and corrosion resistance.
• Port– Cylinder ports are threaded holes that are used to connect hydraulic fittings (used to introduce hydraulic fluid into the cylinder). Ports may be located on any side of the cylinder head and cap end covers.
• Stroke– The stroke is the distance the piston can travel through the cylinder tube, from fully closed to fully open.
