Oil seal 18x32x10 AS NBR

The 18×32×10 mm AS type shaft seal, made of nitrile rubber (NBR), is intended for sealing rotating shafts in industrial gearboxes, electric motors, agricultural and construction machinery and general-purpose drives. The AS profile corresponds to the DIN 3760 standard and belongs to the standard class of industrial rotary shaft seals - the equivalent of the so-called oil seal (simmering). The profile is based on an elastomer (rubber) outer casing, which provides static sealing in the housing without the need for sealing compounds, while compensating for small bore deviations and thermal deformation. The internal steel metal reinforcement gives the seal the necessary rigidity. The sealing lip is short, flexible and pressed against the shaft surface by a spring, which ensures constant contact at varying rotational speeds. The AS profile is also fitted with an additional dust lip, which protects the sealing space from light to moderate external contamination. The equivalent of the AS profile is the Simrit/Freudenberg BASL - a standard oil seal with a rubber outer casing and a dust lip.
