High-Performance Wear Rings for Hydraulic Cylinders and Linear Motion Systems

KAFLON Hydraulic Wear Rings are engineered to guide and support piston rods and pistons in hydraulic cylinders, preventing metal-to-metal contact, reducing friction and wear, and extending the service life of hydraulic systems.

Designed for demanding applications including construction machinery, industrial hydraulics, mobile hydraulics, and heavy-duty equipment, KAFLON wear rings provide reliable guidance performance under high loads, side forces, and harsh operating conditions.

What Is a Hydraulic Wear Ring?

Guiding Components for Hydraulic Cylinder Performance

A hydraulic wear ring, also known as a guide ring or bearing ring, is installed between the piston or piston rod and the cylinder housing.

Its primary functions include:

Preventing direct metal-to-metal contact,Extending cylinder service life

Supporting radial loads and side forces

Maintaining proper alignment of moving components

Reducing friction and improving sealing performance

Piston seals

Rod seals

Scraper seals

Backup rings

FAQ

What is a hydraulic wear ring?

A hydraulic wear ring is a guiding element installed in hydraulic cylinders to prevent metal-to-metal contact between moving components and support radial loads.

What materials are used for hydraulic wear rings?

Common materials include PTFE compounds, phenolic resin, POM, PA, and PEEK, selected according to load, temperature, and application requirements.

What is the difference between a wear ring and a hydraulic seal?

A hydraulic seal prevents fluid leakage, while a wear ring guides moving components and absorbs side loads to protect the cylinder system.

Can KAFLON provide custom wear ring designs?

Yes. KAFLON provides customized wear rings according to customer drawings, groove dimensions, operating conditions, and material requirements.
