Modular Rotary Shaft Seals | Simmerring Modular Sealing Solution 1 FKM/FKM (MSS 1) Product description The standard Simmerring BA...U...SL as basic module combined with an inner buffer seal with sine wave-shaped sealing lip as one-piece solution, e.g., for drive technology applications. A proven type with high resistance to soiling and metal abrasion Product advantages ■ Broad range of applications, for example in industrial gear- ■ Reliable sealing of the housing bore, even with increased roughness of the bore, thermal expansion and split housings, thus a sealing of low viscosity and gaseous media is also ■ Very long service life and reliability, especially when subject to strong external dirt and/or contamination (metal abrasion, cast sand) of the lubricant ■ Optimal for vertical unit application ■ Very narrow axial design ■ Reliable sealing of the housing bore etc. Product properties ■ Outer casing: elastomer (smooth) ■ Spring-loaded sealing lip and sealing lip with helix edge without spring ■ Modern sealing lip profile ■ Friction-optimised primary seal lip 1 made from fluoro rubber ■ Secondary seal lip with additional dust lip 2 ■ Grease filling with special lubricant Kluber Petamo Operating conditions Max. permissible values depend on the other operating Fitting & installation Housing bore Careful fitting according to DIN 3760 is a prerequisite for the correct function of the seal -* Technical Manual. 1 Freudenberg Simrit GmbH & Co.
