The DBH 9745/85 radial shaft seal is a lip seal that mounts in cylindrical housings to retain lubricant and block the entry of dust, water or particles in equipment with a rotating shaft. Its A 156 design and dimensions of 28 mm shaft, 40 mm housing and 8.00 mm height make it suitable for gearboxes, pumps, electric motors and industrial transmissions. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

This item is a DBH radial shaft seal identified by the designation 9745/85. Its main attributes are: shaft diameter of 28 mm, housing diameter of 40 mm and height of 8.00 mm. The A 156 design corresponds to a specific construction configuration from the manufacturer, which defines the lip profile, the metal body and the retaining spring. It is a precision component that works in direct contact with the shaft, so its correct selection depends on these three dimensions matching the housing and shaft of the machine.

Typical applications for an oil seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the oil seal serves to confine the oil or grease inside the assembly and prevent external contaminants from entering the bearings or gears. It is also used on fan, mixer and conveyor shafts, where continuous rotation demands reliable, low-friction sealing.

To install a radial shaft seal correctly, check that the shaft has no burrs, scratches or wear in the contact area. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and fit the oil seal with an installation tube that presses on the outer diameter, never on the lip. Perpendicularity with respect to the shaft is critical: a tilted installation causes premature leaks. If the shaft shows a worn track, consider using a repair sleeve or consult our technical team.
