PRODUCT DESCRIPTION

Pressure-resistant type for use without back-up ring in pressurised units such as hydraulic pumps and motors as well as hydrodynamic couplings. Features a patented sealing edge design that keeps the lip profile stable up to twice the pressure level of the conventional design (BABSL).

PRODUCT ADVANTAGES

• Used preferably in pressurised units
• Reduction of the friction of 50% in comparison to the conventional design (BABSL)
• Reliable sealing of the housing bore, even with increased roughness of the bore, thermal expansion and split housings
• Advantages when sealing low viscosity and gaseous media
• Additional dust lip as additional seal against moderate to medium dust and dirt ingress from outside
• Small axial dimensions (Note: can lead to temperature increase from frictional heat)
