Gamma seals are used in a wide range of applications. The springs of this seal provide a constant axial load which translates into a constant low friction in the engine. The customized design is supported by finite element analysis (FEA) for optimal performance. We offer two types: The RB type and 9RB.

Because of the Gamma seals’ protective metal case it can operate in rough operating conditions. During operation the lip seals against the housing under a contact pressure which is calculated for proper sealing. The sealing lip tends to exert less contact pressure as the speed increases due to centripetal force, which contributes to proper sealing performance. As a result, the seal operates both as a ‘deflector ring’ and ‘clearance seal’.
