Industrial Seal Inc. offers a complete line of wear rings and bearing products to fit any application. The product offering meets the full spectrum of needs, from heavy duty hydraulic cylinders operating under the highest temperatures and pressures to pneumatic applications requiring low friction, long life and self-lubrication.

  • WPT Profile, Tight-Tolerance Piston Wear Ring

    WPT tight-tolerance piston wear rings are the premier bearings for light- to heavy -duty hydraulic applications. WPTs are available in standard sizes from 1" up to 12" bore diameters (larger sizes upon request). WPT wear rings feature chamfered corners on the I.D. and are designed to snap closed during assembly to hold tight against the piston, eliminating bore interference and simplifying installation.

    Technical Data

    Standard Material
    W4733 WearGard

    Radial Tolerance
    +.000"/ -.002" (up to 6" O.D.); +.000/ -.003" (6" to 12" O.D.)

    End Cuts
    Butt Cut, Angle Cut, Step Cut

    Options
    Virtually any width can be produced without assessing a setup charge. Additionally, other cross-sections not shown are available when required.

  • WRT Profile, Tight-Tolerance Rod Wear Ring

    WRT tight-tolerance rod wear rings, when combined with the WPTprofile, complete the premier cylinder bearing system. Recommended for light- to heavy -duty hydraulic applications, they are available in standard sizes from 7/8" up to 7" rod diameters (larger sizes upon request). WRTs feature chamfered corners on the O.D. and are designed to snap open during assembly to hold tight against the head gland, eliminating rod interference and simplifying installation.

    Technical Data

    Standard Material
    W4733 WearGard

    Radial Tolerance
    +.000"/-.002" (up to 5-3/4" I.D.); +.000/-.003" (5-3/4" to 7" I.D.)

    End Cuts
    Butt Cut, Angle Cut, Step Cut

    Options
    Virtually any width can be produced without assessing a setup charge. Additionally, other cross-sections not shown are available when required.

  • WN Profile, Commercial Wear Ring

    WN commercial wear rings can be used for either pistons or rods and are the most economical bearing solution for light- to medium-duty hydraulic applications. MolyGard bearing material offers the combination of long life and high strength. WNs are available in standard sizes (1/8" cross-section) from 3/4" up to 11-3/4" rod diameters and 1" to 12" bore diameters (larger sizes upon request).

    Technical Data

    Standard Material
    W4650 MolyGard

    Radial Tolerance
    +.000"/-.005"

    End Cuts
    Butt Cut only

    Options
    Virtually any width can be produced without assessing a setup charge. Additionally, other cross-sections not shown are available when required.

  • PDT Profile, PTFE Wear Strip for Rod and Piston

    PDT wear strip is available in a variety of PTFE blends and provides excellent low-friction performance in pneumatics and light-duty hydraulics. PDTs are available in cut-to-length versions as well as bulk strip. Cut-tolength part numbers reduce prep time by providing precision end cuts and ready-to-install diameters. Bulk strip PDTs offer versatility and reduce part number inventory by providing universal sizing in one part number.

    Technical Data

    Standard Material
    0401 40% Bronze-Filled PTFE
    0307 23% Carbon, 2% Graphite-Filled PTFE

    +.000"/-.004"

    End Cuts
    Butt Cut, Angle Cut, Step Cut

    Options
    Virtually any width, diameter and cross-section can be produced without assessing a setup charge.

  • PDW Profile, Machined Wear Ring for Rod and Piston

    PDW wear rings are precision machined PTFE bearings, lathe cut to exact size and shape. PDWs offer precise fitting and easy installation. The wide range of available PTFE blends gives these machined wear rings versatility to accommodate any pneumatic or light-duty hydraulic application requiring low friction and high temperature capabilities.
