Item description
Properties:
Radial rotary shaft seals serve to seal rotating machine components. The mainly consist of a rubber part with a reinforcement plate and a worm spring made of spring steel. Depending on the intended use, there are three basic types: the standard construction forms A, B and C.

Materials:
NBR (72 Shore A)

Temperature range:
-30°C to +100°C

Running speed:
Max. 14 m/s

Optional:
Material FKM (-20°C to +200°C, running speed max. 37 m/s) -V

Designs:
A (commonly used market designations: BA, (TR)A, CB, 827N, DG, SC, WA) /
AS (commonly used market designations: BA SL, (TR)E, CC, 827S, DGS, TC, WAS):

The rubber-elastic external jacket can bridge the gap between thermal expansion and a high degree of roughness in the housing hole. There is no frictional corrosion. Changing the seal frequently prevents damage to the housing hole. Is suited for sealing gaseous or low-viscosity media. The design AS is provided with additional dust lip to safeguard against dirt and corrosion.

B (commonly used market designations: B1, (TR)C, BB, 822N, DF, SB, WB) /

BS (commonly used market designations: B1 SL, (TR)D, BC, 822S, DFS, TB, WBS):

Metallic housing, press in slightly during installation. Requires narrower tolerances of the housing hole, to ensure a seal even at the outer casing. BS design with an additional dust lip against dirt and risk of corrosion.

C (commonly used market designations: B2, (TR)B, DB, 824N, DFK, SA, WC) /

CS (commonly used market designations: B2 SL, (TR)F, DC, 824S, DFSK, TA, WCS):

Metallic housing with reinforcing cap. Sealing and assembly as design B. Used in preference in harsh operating conditions and for larger dimensions. Is less sensitive to assembly errors due to the reinforcing cap. CS design with additional dust lip against dirt and risk of corrosion.

AD / BD:

The designs AD or BD with two sealing lips are used to seal and separate two media.

AO / BO:

The designs AO and BO are designed without the garter springs. They are designed only for minor seal cases.
