The DBH 8786 radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating equipment. With a 54 mm shaft diameter, a 79.35 mm housing bore, and a height of 12.70/19.00 mm, it fits assemblies where axial space is tight but reliable sealing is still required. The elastomer resists oils and greases, making it a practical choice for replacement and maintenance work.

This seal carries the designation 8786 and the design A 103-H-H. The A 103-H-H configuration combines a sealing lip with a reinforced body, which suits rotating shafts. The dimensions are: shaft 54 mm, housing 79.35 mm, and height 12.70/19.00 mm. DBH is a brand we supply, so you can count on standard dimensions for replacement.

Common uses include gearboxes, pumps, electric motors, rollers, and power transmission equipment. In dusty, wet, or chip-prone areas, the lip helps prevent oil leakage and keeps particles out, which supports the life of bearings and gears. You will often find this seal on production lines, in food plants, and on conveyor systems that run with permanent lubrication.

When installing, check that the shaft has the right hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip with the same oil used in the equipment, then press it in with a tube that contacts the outer diameter to avoid damaging the seal. Selection should account for peripheral speed, operating temperature, and chemical compatibility between the elastomer and the fluid being retained.

If you need an equivalent size or a close variant, send us the part number 8786 along with your shaft, housing, and height dimensions. We can also look for alternatives in other brands or with slight dimensional differences, as long as the space allows. Our team can help you choose a seal that fits your equipment without compromising sealing performance.
