The DBH 8703 is a radial shaft seal of the lip type. It fits into the bore of a rotating assembly, where it holds lubricant in and keeps dust, water and other particles out. With a 42 mm shaft, a 62 mm housing bore and a 6 mm height, it sits in the compact range for medium-section shafts. Gearboxes, pumps, electric motors and transmission equipment running on oil or grease are the usual homes for this seal.

The code breaks down as follows: shaft diameter (d) 42.00 mm, housing diameter (D) 62.00 mm, height (h) 6.00 mm. The stated design is Lx, meaning one sealing lip combined with an outer metal case. The lip rides against the rotating shaft while the case seals against the housing bore, so lubricant stays where it belongs and outside contamination stays out.

You will find this seal in gearboxes, centrifugal pumps, electric motors, speed reducers, conveyor rollers and power transmission equipment in general. In every one of those spots it keeps bearings and gears away from premature wear by holding the lubricant clean and in position. Maintenance teams treat it as a standard item for both preventive and corrective work.

During installation, inspect the shaft for burrs or marks that could cut the lip, apply lubricant to the lip before pressing it in, and use a driver that pushes on the metal case rather than the lip. Shaft speed, working temperature and the type of lubricant all play a role in selection. Where dirt is heavy or speeds are high, a version with an auxiliary lip or dust guard may be the better choice.
