Standard rotary and static oil seal dimensions cross-referenced by shaft diameter, bore diameter and width, so engineers can identify the right seal and confirm the sealing profile for a given housing. ARC molds these seals to spec in the elastomer your application requires.
Request a Quote Oil Seal Products →An oil seal size chart cross-references rotary and static oil seals by shaft diameter, bore diameter and width, so you can confirm the exact sealing profile a housing needs. Engineers and buyers searching for an oil seal cross-reference, rotary shaft seal dimensions or a radial lip seal size chart are usually matching a worn seal or a new bore to the right part number and section — verifying the outer diameter presses cleanly into the bore while the lip rides true on the shaft. Reading it correctly keeps the callout right on the drawing and quotable on the floor.
ARC molds oil seals to your shaft, bore and width in the elastomer your service conditions demand — nitrile, Viton, silicone, EPDM and more — for temperature, pressure and media compatibility. Every seal is produced under our ISO 9001:2015 and IATF 16949:2016 quality systems. Send your dimensions or a drawing and our engineers confirm the profile, material and tooling, typically with a quote in one business day.
American Rubber Corp manufactures custom and standard rubber rotary oil seals (shaft seals) in metric and imperial sizes for automotive, industrial, hydraulic, and agricultural applications.

Materials:
Match the seal to your shaft speed, temperature, pressure, and media. Start from the size (shaft/bore/width), then select the elastomer by fluid and temperature. For fluid compatibility see our chemical compatibility guide; for dimensional tolerances see the RMA tolerance chart. Still unsure? Our engineers will recommend a construction for your application.
Send your shaft/bore/width, material, and quantity, or upload a drawing, and we will quote your rotary oil seals. Use the form below or email us directly.
