Gamma Seal Description

Gamma Seal

Taking multiple names such as RB axial rings, axial seals, deflector rings, or flingers, Gamma Seals are commonly used in power transmission systems and hydraulic applications.

The design of a Gamma Seal consists of an outer metal case, embedded with an 80 durometer nitrile sealing lip. It is engineered to rotate while maintaining its proper sealing function, making it compatible in both dynamic and static operations.

Gamma Seals work in the same way V-Rings do, as they shield the oil seal from contaminants, with the added protection of metal casing.

Benefits of Gamma Seals

Gamma Seals have many benefits, including:

  • Reduced resistance as rotary motion intensifies
  • Smooth and simple installation
  • Substitutes well for a V-Ring
  • Increased seal protection with outer metal casing
  • Deflection effect during rotation, excluding media from penetrating the seal
  • Decreased frequency of downtime for repairs

RB and 9RB Gamma Seals

Gamma Seals are made in RB and 9RB style variations, with the difference being 9RB Gamma Seals’ extended metal surface for increased protection.

 

 

Gamma Seal Part Number System

Global O-Ring and Seal’s Gamma Seal part numbers are designed to describe the Shaft Diameter and Gamma Seal Outside Diameter (in millimeters) and style. We utilize two naming conventions which are shown in the examples below. The first example shows a Gamma Seal accommodating a Shaft Diameter of 100mm, with a 9RB style. The second example shows a Gamma Seal with an Outside Diameter of 87mm, accommodating a Shaft Diameter of 65mm, with a 9RB style.
