In some cases, finding the right shaft seal will simply require that you match your application requirements to one of the standard designs that have been developed to meet most situations. Very demanding applications, such as those requiring sealing in extreme environments, may necessitate use of a non-standard design. In some cases, you may benefit from developing an entirely new design with the help of our in-house engineering department.

Standard designs are basic lip and case configurations that have proven effective in various applications. Each design is designated by a two- or three- letter alphabetic code (such as “SB” or “SBR”). The first letter of this code always refers to the design of the sealing lip. For example, the “S” in both “SB” and “SBR” denotes a single lip seal with a garter spring. The second (or second and third) letter(s) always refer(s) to the design of the seal’s case. For example, the “B” in “SB” denotes a metal O.D. with rubber on the fluid side for added protection against corrosion. The “BR” in “SBR” denotes a metal O.D. with rubber on the fluid side and a rubber nose for enhanced O.D. sealing.
