SMALLEY Laminar Seal Rings A Smalley Laminar Seal Ring set is a metallic labyrinth seal consisting of multiple rings in a groove. The arrangement and the specific orientation of the rings are dictated by the application and the severity of the environment. There are 16 series of standard imperial and Metric Laminar Seal Ring configurations from which to select. 8 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 operational ring-set configurations in both imperial and 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 to the shaft. Laminar Seal Rings Available From Stock Standard parts from 5/8'' to 50'' and 15 mm to 1,300 mm. Special seals manufactured with No-Tooling-Charges. Smalley's Laminar Seal Rings are interchangeable with FEY Rings. Advantages of Laminar Seal Rings • No friction with other rotating components, ideal for high speed applications. • Prevent dirt and splash water from contaminating components. • When used in conjunction with other seals, Laminar Seals provide a primary seal against severe contamination, before the contaminants come in contact with the secondary seal. • Sets of multiple rings provide an efficient labyrinth seal. • Rings may be produced from a wide variety of alloys to withstand more severe conditions including higher temperatures and corrosive environments. • As a metallic mechanical seal they can outperform rubber seals in durability and life expectancy. • The change from rubber to metal reduces the need for frequent seal replacement.

Single -Turn Laminar Seal Rings Used in a variety of applications, this series of Seal Rings should be utilized for light to medium duty applications, dependent on the ring configuration specified. The sets are comprised of single-turn rings in either 3 rings per set or 5 rings per set. APPLICATIONS: 3 ring sets protect components from low dirt and low splash water contamination. 5 ring sets provide a better labyrinth seal to protect components from medium dirt and medium splash water contamination.

SMALLEY Laminar Seal Ring Applications C. Pulley Idler A. Coupling The seal arrangement in this assembly has been custom designed for optimum protection against contamination. Gases build up pressure in a center cavity, protected on both ends from contaminants entering. B. Bearing Protection The 3 ring set protects the ball bearing from contaminants like dirt and water. The seal retains grease/lubricant and prevents contaminates from penetrating into the critical components of the assembly. C. Pulley Idler The ring set designed in this application extends the life of the ball bearing by...

Single-Turn Laminar Sealing Rings YH or YS are used for a wide variety of applications. They are commonly used to protect bearing systems by retaining grease/lubricant and preventing water or other contaminating liquids from penetrating into the critical areas of an assembly. The alternating (staggered) series YHK and YSK offer (due to an increased labyrinth seal) further improved sealing efficiency. They are often specified where the lubricating grease may liquefy due to higher operating temperatures or where protection against larger amounts of contaminating liquids (such as cooling...

SMALLEY Double-Turn Rings Double-Turn Laminar Sealing Rings offer a higher clamping force when installed in the bore or on the shaft. They are suited for higher operating speeds, have 360° contact (no axial gap) and should be used where application conditions are more severe. One typical application is where high amounts of dirt and dust are present and the ring sets provide the necessary seal against contamination from outside elements. Double-Turn Laminar Ring Sets are also used to protect contacting radial seals, rubber seals, O-rings and other oil seals. For protection in the...

Single-Turn Laminar Sealing Rings QH or QS are used for a wide variety of applications. They are commonly used to protect bearing systems by retaining grease/lubricant and preventing water or other contaminating liquids from penetrating into the critical areas of an assembly. The alternating (staggered) series QHK and QSK offer (due to an increased labyrinth seal) further improved sealing efficiency. They are often specified where the lubricating grease may liquefy due to higher operating temperatures or where protection against larger amounts of contaminating liquids (such as cooling...
