Smalley® Retaining Rings

Laminar Sealing Rings
 

A Smalley Laminar Seal Retaining Ring is a metallic labyrinth seal consisting of multiple rings in a groove. This arrangement of the rings and the specific orientation of the rings are dictated by the application and the severity of the environment. Standard parts from 5/8" to 50" and 15 mm to 1,300 mm. Special Seals manufactured with no-tooling-charges.  They have many advantages including:

• Seals assembly components from contamination

• Numerous configurations available

• Produced from metal and not rubber, neoprene, or other
  non-metallic materials

• Able to withstand high temperatures and corrosive environments

There are 16 series of standard English & Metric Laminar Seal Ring configurations to select from. Eight of these series are sets consisting of single-turn rings. The other 8 series are sets consisting of double-turn rings, Within each series are optional ring-set configurations in both English & metric sizes. The selection of the appropriate set should be determined by the application. For some applications a complete labyrinth configuration (i.e. a complete labyrinth configuration is one which has rings staggered within the set) is necessary due to a severe environment where contamination is highly probable. In other applications design engineers can keep the groove dimensions minimal by specifying laminar sets with rings clinging either to the bore or shaft.
