The DBH 5704 is a radial shaft seal built for rotating shafts, with an Lz lip design that combines a spring-loaded sealing lip with an outer body that seats in the housing bore. Its dimensions are shaft 50 mm, housing 80 mm and width 13 mm. The lip retains oil or grease on the shaft side and blocks dust, water and other particles from reaching the bearing cavity. This seal belongs to the seals and oil seals line that MR Industrial Accessories supplies to plants, workshops and distributors.

Reading the code is simple: the DBH 5704 number identifies the seal, while the three figures that usually follow it describe the bore it fits. In this case the shaft measures 50 mm, the housing bore 80 mm and the overall width 13 mm. The lip, normally an elastomer compound, is pressed against the rotating shaft by a small spring, while the outer case holds the seal firmly in the housing. Because the lip rubs continuously against the shaft, the seal is a wear item and is normally swapped out during scheduled maintenance.

You will find this size on medium-diameter shafts in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission equipment. In each of these assemblies the seal keeps the lubricant where it belongs and keeps the working environment out, which protects the bearings. Machine tools, food processing equipment and hydraulic systems are other places where a seal of these dimensions is used to contain fluid.

Installation has a direct effect on how long the seal lasts. The shaft should be clean and free of burrs, nicks or rust, and the housing bore must match the required diameter and depth. Lubricate the lip before pressing the seal in, keep it square to the bore and avoid striking it. It is also worth checking shaft runout and surface finish, since a rough surface wears the lip faster. Whenever a seal has failed, inspect the bearing and the lubricant before fitting a new one.
