Radial seal RG

rotaryelastomerNBR

Description
The Radial Oil Seal Type RG is a rotary shaft sealing element with an elastomeric outer diameter and a sealing lip designed without an inserted tension spring, resulting in reduced friction on the sealing lip. It is intended for rotating shafts in housings with no internal pressure. Standard elastomer options are NBR and FKM; additional materials are available on request.

Fields of application

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

Main use
Unpressurized sealing for rotating shafts in housings

Materials
Elastomers (standard: NBR, FKM), metal components

Technical values

• Materials (variants): NBR, FKM
• NBR — Pressure: none; Temperature: -30°C / +100°C (material dependent); Speed: depends on material and diameter
• FKM — Pressure: none; Temperature: -20°C / +200°C (material dependent); Speed: depends on material and diameter
• Maximum values (temperature, speed and pressure) are not simultaneously applicable; values vary with material and media
