Cylinder Components: Everything for Hydraulic Cylinder Manufacturing and Repair

The Fundamentals of Building the Perfect Hydraulic Cylinder

A hydraulic cylinder is a precision mechanical masterpiece where every single component plays a critical role in its reliable and efficient operation. The "Cylinder Components" category at Hidraulika Store is a comprehensive collection of all the parts needed to manufacture a new hydraulic cylinder, refurbish an existing one, or modify one for special requirements. From robust cylinder bases and rod guides, to precision pistons, and motion-enabling spherical plain bearings and cylinder & rod ends, you will find everything in one place.

The Main Structural Elements: Rod Guides, Cylinder Bases, and Pistons

The body of a cylinder is built from three main elements responsible for stability and force exertion.

• Rod Guide (Gland): A key component located at the rod end of the cylinder. Its main function is to precisely guide the piston rod without play, while also housing the rod seals and the wiper ring to ensure the leak-free operation of the cylinder. Our selection includes threaded, weld-on, centered, and special cushioned versions.

• Cylinder Base: A typically weld-on element that closes the bottom of the cylinder, which may also include a port for hydraulic connection. A massive design is essential to safely withstand high pressure.

• Piston: The component moving inside the cylinder, on which hydraulic pressure acts, transmitting force to the piston rod. It has grooves designed to house the piston seals. We offer standard, short, heavy-duty, and cushioned pistons for a wide variety of applications.

Connection and Motion: Cylinder and Rod Ends for Stability

Connecting the cylinder to the machinery is the task of the cylinder and rod ends. These components must be both robust for force transmission and provide the necessary freedom of movement. The most popular choice is the weld-on version, which guarantees a durable and massive connection. Due to its excellent value and reliability, the Weld-on Rod End - SN 20 P - WS20N is one of our most sought-after products in this category. In addition to weld-on versions, female threaded, male threaded, and clevis designs are also available. Choosing the right mounting point is essential, so please view our entire range of cylinder and rod ends to find the perfect solution for your machine.

Fine-Tuning the Motion: Spherical Bearings, Bushings, and Pins

The cylinder and rod ends house the components that allow for the cylinder's articulation and fine movement, preventing side-loading on the piston rod.

• Spherical Plain Bearing: The most common solution, providing high load capacity and significant angular movement. Our range includes GE ES (steel/steel), GE ES 2RS (sealed, maintenance-free), and many other types.

• Glycodur Bushing: A maintenance-free, self-lubricating bushing ideal for lower speed but high-load movements.

• Pin: The hardened steel component that secures the spherical bearing or bushing in the clevis mount.

Frequently Asked Questions

• How do I choose the right rod guide? When selecting a rod guide, the most important factors are the piston rod diameter, the inner diameter of the cylinder, and the mounting method (threaded, weld-on). It is also important that the chosen guide can accommodate the desired seals.

• When is a cushioned piston needed? Cushioning is necessary when the piston reaches its end-of-stroke at high speed or while moving a large mass. The cushion slows down the piston over the last few centimeters, preventing a hard mechanical impact, which reduces noise and system vibration, and increases service life.

• What is the difference between GE ES and GE ES 2RS spherical plain bearings? "GE ES" is an open, steel/steel sliding contact spherical bearing that requires regular lubrication. The "2RS" designation means the bearing is sealed on both sides, protecting it from contaminants and retaining the factory grease, thus providing maintenance-free operation.
