Gufero 70x80x5 NBR-WAO Dichtomatik

Product detailed description

The 70x80x5 NBR-WAO seal from Dichtomatik is a spring-free shaft seal designed for basic shaft sealing. This component is made of nitrile-butadiene rubber (NBR), which is known for its excellent resistance to oils, greases and other petrochemicals. NBR is also abrasion resistant and has good mechanical properties, making it suitable for applications with moderate pressure loads.

The dimensions of the seal are precisely defined: the inner diameter (d) is 70 mm, the outer diameter (D) is 80 mm and the height (H) is 5 mm. These dimensions allow for precise seating in the respective bearing space, ensuring effective sealing. The absence of a spring indicates that this type of seal is intended for applications where high axial loads are not required or where a simpler design is required.

The seal is fitted with a dust boot which provides additional protection against dirt and contamination, extending seal life and reducing the risk of shaft damage. This product is ideal for use in environments where basic protection against contamination and lubricant leakage is required, and is suitable for applications with lower operating pressures.
