Guide Rings for Hydraulic and Pneumatic Applications

Guide rings, also known as wear rings or bearing rings, play a crucial role in hydraulic and pneumatic cylinders by supporting and guiding the piston and rod. They prevent metal-to-metal contact between moving parts and the cylinder bore, protecting the cylinder from wear and damage. This extends the cylinder’s lifespan while ensuring smooth and efficient operation.

Our range includes:

Cut/Split Rings

Easy to install and ideal for less demanding applications.

Solid/Continuous Rings

Provide superior stability and enhanced load-bearing capacity.

Wrapped Rings

Constructed from strips of material wrapped around the piston or rod for added durability.

Composite Rings

Engineered from combined materials for optimized performance and wear resistance.

Materials

Guide rings are typically made from materials with excellent wear resistance, low friction, and the ability to withstand the operating conditions:

PTFE (Teflon)

Low friction, excellent chemical resistance, and suitable for high-speed applications.

Nylon

Good wear resistance and impact strength.

Acetal

High stiffness and dimensional stability.

Bronze-filled PTFE

Enhanced wear resistance and load-bearing capacity.

Applications

Guide rings are used in a wide range of hydraulic and pneumatic systems

Hydraulic Cylinders

In construction equipment, agricultural machinery, industrial presses, and mobile hydraulics.

Pneumatic Cylinders

In automation systems, robotics, packaging equipment, and manufacturing processes.

Telescopic Cylinders

Where multiple stages of the cylinder extend and retract.

Why Use Guide Rings?

Prevent Wear and Scoring

Guide rings prevent direct contact between the piston/rod and the cylinder bore, minimizing wear and scoring, which can lead to leaks and premature failure.

Extend Cylinder Life

By reducing wear, guide rings significantly extend the service life of the cylinder, reducing maintenance costs and downtime.

Improve System Performance

Guide rings ensure smooth and stable movement of the piston and rod, improving the overall performance and efficiency of the hydraulic or pneumatic system.

Reduce Friction

They minimize friction between moving parts, contributing to smoother operation and energy efficiency.

Selecting the Right Guide Ring

Choosing the correct guide ring depends on several factors

Cylinder Dimensions

The diameter of the piston rod or piston and the cylinder bore.

Temperature Range

The range of temperatures the ring will be exposed to.

Operating Pressure

The maximum pressure the guide ring needs to withstand.

Fluid Compatibility

The type of fluid or gas the ring will be in contact with.
