Radial shaft seal RP

rotaryelastomerNBR

Overview The Radial Oil Seal Type RP is a rotary shaft seal similar to the Oil Seal design type RD, but pressure resistant. It features an elastomeric outer diameter, an inserted tension spring and an additional dust lip for applications with a high dust content from outside. It is suitable for rotating shafts in housings with no internal pressure or with pressure differentials up to 0.5 MPa. Standard elastomer materials are NBR and FKM; further materials are available upon demand.

Fields of application

• static
• dynamic
• single acting
• double acting
• linear
• rotating
• oscillating

Main use pressurized sealing for rotating shafts

Materials elastomers, metal

Technical values
