Rotary Seals
Gamma ring
Axial acting rotary seal that is predominantly used together with Oil seals, to provide external protection for the system against impurities such as dust, dirt and water spray.
Gamma ring GB
The Gamma ring GB is an axial sealing, single-acting sealing element for non-pressurized shaft and bearing sealing applications against the intrusion of contamination and water spray from outside. The metallic fit on the inner diameter, ensures a secure grip on the shaft. Due to the extended metal ring of the Gamma ring GB design, this guarantees good protection against coarse contamination.
In contrast to radial oil shaft seals, Gamma rings seal against the vertical arranged front surface. Metal casing comes in standard unalloyed carbon steel as well as stainless steel variants.
Standard elastomer materials for the flexible seal lips are NBR and FKM. Further materials are available upon demand.
