The DBH 9777Pol radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its Lx bidi design works in both directions of rotation, so it is suitable both for equipment that reverses motion and for assemblies where the direction is not defined. With 48 mm shaft, 62 mm housing bore and 7 mm height, it is a commonly used size in pumps, motors and gearboxes.

This item is a seal from the DBH brand, identified by part number 9777Pol. Its dimensions are 48 mm shaft diameter, 62 mm housing bore diameter and 7.00 mm height. The design indicated as Lx - Bidi corresponds to a sealing lip that seals in both directions of rotation, with a body that is press-fitted into the machined cavity. It is a direct replacement part: it is replaced by another with the same designation or by an equivalent that respects those three dimensions.

Typical applications for a seal of this size appear in centrifugal pumps, electric motors, gear reducers, transmission gearboxes and process equipment. In all these cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that wear down bearings and gears. Because it is bidirectional, it is also used on shafts that rotate in both directions or in assemblies where the seal may face pressure from either side.

To select it properly, check that the shaft diameter is within the tolerance recommended for radial shaft seals and that the housing has no burrs or marks that could damage the lip during installation. The 7.00 mm height must match the depth of the cavity. When installing, lubricate the lip with the same oil used in the equipment, seat the seal squarely and tap on the outer edge, never on the lip. If the shaft shows wear or a groove, consider a nearby size or a repair sleeve.

If you need an equivalent or a nearby size, send us part number 9777Pol along with the shaft, housing bore and height dimensions, and a photo of the old seal if possible. With that data we can look for an alternative from the same brand or from another brand that MR Accesorios Industriales carries, always respecting the mounting dimensions. We can also advise you on whether the Lx bidi design is right for your application or whether another type of lip is preferable.
