Gamma seal GA

rotaryelastomerNBR

Product overview
The Gamma Ring GA is an axial, single-acting sealing element designed for non-pressurized shaft and bearing applications to prevent contamination and external water spray. A metal fit on the inner diameter secures the component to the shaft and provides mechanical reinforcement. Unlike radial oil shaft seals, Gamma Rings seal on the front (axial) face.

Materials

• Metal casing: standard unalloyed carbon steel; stainless steel variants available
• Flexible sealing lips (standard elastomers): NBR, FKM
• Other materials available on request

Technical values

• Pressure: not designed for pressure sealing
• Temperature (material dependent): NBR: -30°C to +100°C; FKM: -20°C to +200°C
• Maximum surface speed: up to 8 m/s
• Warning: Maximum values for temperature, speed and pressure are not simultaneously applicable and depend on material and media.

Main use
Axial/front-face anti-contaminant shaft outlet seal with mechanical reinforcement for protection of shafts and bearings against particulate ingress and water spray.
