Simmerring MSS 1

Product catalog summary

Product Description: The Simmerring Modular Sealing Solution 1 (MSS 1) is designed for a broad range of applications, particularly in industrial gearboxes. It ensures reliable sealing even with increased bore roughness, thermal expansion, and split housings, making it suitable for low viscosity and gaseous media. The product is noted for its long service life and reliability, especially in environments with external dirt and contamination.

Product Advantages: The MSS 1 offers optimal performance for vertical unit applications and features a very narrow axial design. It provides reliable sealing of the housing bore and is equipped with a modern sealing lip profile and friction-optimized primary seal lip made from fluoro rubber.

Product Properties: The outer casing is made of smooth elastomer, with a spring-loaded sealing lip and an additional dust lip. The primary seal lip is made from fluoro rubber 75 FKM 585, and the secondary seal lip includes an additional dust lip. The product is filled with a special lubricant, Klüber Petamo GHY 133 N.

Material and Components: The seal is constructed from fluoro elastomer with a hardness of 75 Shore A. It includes a metal insert made from unalloyed steel and a spring made from spring steel.

Operating Conditions: The MSS 1 operates effectively within a temperature range of -25 to +160 °C, with a maximum speed of 6 m/s and pressure up to 0.05 MPa. The permissible values depend on other operating conditions.

Fitting & Installation: Proper fitting according to DIN 3760 is essential for the seal's function. The shaft should have a tolerance of ISO h 11, runout IT 8, and specific roughness and hardness parameters. The housing bore should have a tolerance of ISO H8 and specific roughness for the metal outer surface.

Range of Dimensions: The Simmerring MSS 1 is suitable for shaft diameters ranging from 35 to 145 mm.

Additional Features: The standard Simmerring BA...U...SL serves as a basic module, combined with an inner buffer seal with a sine wave-shaped sealing lip, providing high resistance to soiling and metal abrasion in the oil chamber.
