Guide ring FS

Product overview
The Guide Ring FS prevents metallic contact between the bore and the piston and safely absorbs lateral forces. Guide Rings are manufactured on turning machines in various materials with a diagonal cut. They are essential for safe operation of hydraulic or pneumatic systems and must be selected and aligned to the prevailing application conditions.

Typical construction and standard materials
Standard Guide Rings are produced from filled PTFE, thermoplastic materials, or fabric-reinforced phenolic or polyester resin. Compressive strength depends on the chosen material and typically ranges from 15 to 100 N / mm².

Load calculation
To calculate the maximum load per Guide Ring: lateral force / projected surface x 0.75

Fields of application

• static
• dynamic
• single acting
• double acting
• linear
• rotating
• oscillating

Main use
Guiding in dynamic applications

Materials (available variants)

• PTFE (including PTFE with filling material)
• thermoplastic-based
• fabric-based laminate (fabric-based laminate, polymers, UHMW-PE)
