- Outer casing: elastomer (smooth)
- Spring-loaded sealing lip and sealing lip with helix edge without spring
- Additional dust lip
- Modern sealing lip profile
- Friction-optimised primary seal lip 1 made from fluoro rubber 75 FKM 585
- Secondary seal lip with additional dust lip 2
- Grease fitting with special lubricant Kluber Petamo GHY 133 N.
Product advantages
- Broad range of applications for example in industrial gearboxes
- 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 also possible
- 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.
Application
- Industrial gearboxes.
