Guide strip FM

Product description
Guide Strips FM are manufactured from endless material and can be cut to length to match the application diameter. They serve as piston or rod guide rings to prevent metal-to-metal contact and to absorb lateral forces generated during operation. Guide Strips are machined on turning equipment and supplied in a range of materials with a diagonal cut. Correct selection and alignment are required for safe operation of hydraulic and pneumatic systems.

Standard construction
Standard Guide Strips are produced from filled PTFE, thermoplastics or fabric-reinforced phenolic or polyester resins. Compressive strength depends on the material and typically ranges from 15 to 100 N/mm². To estimate maximum load per Guide Strip, use: lateral force / projected surface × 0.75.

Fields of application

• static
