Oil Seal BO

Oil seal in the standard version with a metal outer jacket, without spring on the sealing lip.
Standard material
NBR 70
Color: green / black
Reinforcement ring: non-alloy steel according to DIN EN 10139
Secondary seals, for example a seal against dust, dirt or splash water with electric motors and as a seal against grease.
The WBO is a single-acting oil seal for rotating shafts. Less friction is created by the closed lip design without spring. As a result, the closing function is reduced in comparison with the oil seal with spring. The elastomeric outer jacket makes a good static seal possible and offers good compensation of the expansion, for example, in light metal housings. Moreover, it guarantees a better seal at relatively large roughnesses, a safe seal at divided houses as well as a good static seal with liquid or gaseous media.
Good chemical resistance to various mineral oils and fats.
Operating parameters
Pressure (MPa / bar): 0/0
Temperature (° C): -40 to +100
Rotation speed (m / s): ≤6
Suitable auxiliary tools must be used for assembly. It is advisable to shape the installation space in such a way that the oil seal in the housing is axially supported.
Other dimensions and other types such as for example dust lip, ridges on the sealing lip, other steel quality of the reinforcement ring can be manufactured as well as all possible special types. With non-standard dimensions, minimum order quantities may be required.

Oil seals are rotary seals. They are used for sealing rotating or swiveling machine parts, mainly on shafts. The application areas of the oil seal are diverse and are located at all levels of machine and equipment construction.

Applications for oil seals
These shaft seals are used in the construction of engines, industrial drives, geared motors, electric motors, combustion engines, pumps, drive systems, agricultural machines, construction machines, household appliances, washing machines (for household and industry), dishwashers, large machines, rolling machines and shipbuilding and wind power stations, etc.

Oil seal materials
These rotary seals are available in various materials, such as NBR, FKM, VMQ, ACM, EPDM, HNBR, etc.
Oil seal BO has no spring and no dust lip. The oil seal is made of steel.
