WBS

Rotary shaft seal in standard design with a metal outer surface and a spring-energised sealing lip made of elastomer. In addition, the standard model is available with a protective lip (WBS) on the air side.

Description
Product group: Rotary shaft seal
Design: B = outer surface metal
Model: S = protective lip
Seal material: NBR 70
Colour: black
Stiffening ring: non-alloy steel according to DIN EN 10139
Tension spring: non-alloy spring steel according to DIN EN 10270-1

Areas of application
Sealing of rotating machine elements such as shafts, hubs and axles.

Function
The WBS is a single-action rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing ­action (WBS) on the side facing away from the medium, against dirt accumulation from the outside. Tight and accurate fitting is achieved by the metal outer surface. The WB model has limited sealing action with thin fluid or gaseous media and with split housings. To guarantee a high degree of static sealing on the outer surface, better surface treatment of the housing bore is required or an additional coat of paint should be applied to the outer surface. 

Media
Good chemical resistance to diverse mineral oils and greases.

Operational application limits
Pressure (Mpa/bar): ≤ 0.05/0.5
Temperature (°C): -40 to +100
Peripheral speed (m/s): ≤ 12
