The DBH 5474 is a radial shaft seal from the DBH line, built as a lip seal with spring and known as an Lz design. It sits in the housing bore and rides against the rotating shaft, holding lubricant in and keeping dust, water and chips out. Shaft 88 mm, housing 120 mm, height 13.00 mm: those three figures define the 5474 designation, and they are what you should confirm before ordering. MR Industrial Accessories LLC supplies this brand and can walk you through the selection.

Read the code in two parts. The 5474 tells you the size inside the DBH range; the letters DBH identify the line. Then match the numbers to your equipment: 88 mm is the shaft diameter (d), 120 mm is the housing bore (D) and 13.00 mm is the height (h). The Lz design means the seal has a sealing lip with a spring, which is the arrangement used on rotating shafts that run with lubrication. If the housing bore or the shaft measures differently, the seal will not seat or seal correctly, so verify both before installation.

Typical service is in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission assemblies where a shaft turns inside a fixed housing. The seal does two jobs at once: it keeps oil or grease from leaking out along the shaft, and it keeps contaminants from working their way in. In dirty or wet areas, that second job matters for the bearings nearby, since incoming grit and water are what shorten their service life and create unplanned downtime.

Selection comes down to shaft speed, operating temperature and the lubricant in use. The Lz lip with spring suits rotating shafts at moderate speeds and low pressures. When you install the seal, coat the lip with lubricant first, inspect the shaft for burrs, nicks or a worn track, and press the seal in squarely rather than driving it in at an angle. A shaft with a visible wear groove may call for a seal with an auxiliary lip.

If you are replacing an old seal or looking for an equivalent, send the code 5474 or the three dimensions. A photo of the removed seal or the housing drawing works just as well. MR Industrial Accessories LLC checks the details and comes back with the option that fits your equipment without compromising the seal or the service life of the assembly.
