Wear Rings Guide Rings

  • Wear Rings / Guide Rings

    M Seals manufactures wear rings/guide rings for rod and pistons with precise tolerance from a variety of materials such as lubricated polyester fabric laminate, reinforced polyacetal, lubricated nylons, PEEK, PTFE and polyimide.

    The main characteristics of M Seals wear rings are:

    • Simple manufacture of groove and assembly
    • High mechanical strength and resistance to heavy radial loads
    • Low break-out and running coefficient of friction (between 0.05 and 0.1 on steel when lubricated)
    • Large selection of sizes.

    Operating conditions

    Our wear rings are particularly suitable for replacing tra­ditional soft metal bearings, as the low friction benefits enable them to operate effectively in conditions of minimal lubrication. The wear rings are recommended to be used in the following conditions:

    • Temperature: -40°C to +130°C
    • Fluids: mineral based fluids, wa­ter/glycol, water emulsions, phosphate esters (non-flam­mable)
    • Fluid pressure: no limitation
    • Radial load: in normal lubricated con­ditions and speeds up to 30m/min, the maximum radial load can be calculated from the formula:
    P= D x E x Ps

    Surface finish

    To ensure long life of the wear rings, the surface finishes must not exceed those indicated for the seal being used.

    Assembly

    Due to wear rings being split, they may naturally spring out of round. To avoid potential damage during assembly, recommended lead-in chamfers should be incorporated in the end of the cylinder bore or rod ends. Details of lead-in chamfers are given for specific seals in our catalogue, or can be obtained from our technical team.

    No special assembly instructions are necessary, although lubrication is desirable and attention to cleanliness is important.
