The DBH 1179 radial shaft seal is a lip seal that mounts on a 56 mm shaft and seals against a 112 mm housing, with a height of 8.00/10.00 mm and A 293 design. Its function is to retain lubricant inside the assembly and stop the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in rotating equipment that works with oil or grease and needs a reliable seal at the point where the shaft passes through the housing.

This item is a seal from the DBH line, identified with part number 1179. Its dimensions are a 56 mm shaft, a 112 mm housing and a height of 8.00/10.00 mm, with an A 293 design. That combination of diameters and height defines the mounting interference and the space available in the housing. The A 293 design corresponds to a lip and body geometry that must be respected when replacing the part so as not to alter the seating or the sealing performance.

It is used in gearboxes, pumps, electric motors, mixers and power transmission equipment where the shaft rotates inside a fixed housing. It also appears in continuous process machines, where a loss of lubricant or the entry of contaminants forces the line to stop. In those cases, the seal works alongside the bearing or bushing it protects, and its service life is tied to the surface condition of the shaft and the cleanliness of the environment.

To select it properly, check that the shaft has no burrs or wear on the sealing track and that the housing is clean and free of deformation. The 8.00/10.00 mm height allows for mounting variants, so it is advisable to confirm the actual space in the housing. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows a marked wear track, consider a nearby size or an alternative design.

If you need an equivalent or a close size, send us part number 1179 along with the shaft, housing and height dimensions you have on the equipment. A photo of the old part and the housing also helps. At MR Accesorios Industriales we compare that data against the manufacturer's product page and offer you alternatives within the same radial shaft seal category so you can complete the replacement without stopping maintenance.
