The DBH 5289 is a radial shaft seal that sits between a rotating shaft and a stationary housing. It keeps lubricant in and keeps dust, water, and other particles out. The seal fits a 30 mm shaft, a 50 mm housing bore, and has a 10 mm height; its Lz design identifies a lip seal with a spring. This size appears often in pumps, motors, gearboxes, and power transmission equipment. MR Industrial Accessories supplies it as a brand.

The code 5289 belongs to the DBH line of radial shaft seals. Its dimensions are: shaft 30 mm, housing 50 mm, width 10 mm. The Lz design means the seal has a sealing lip and a spring, intended for rotating shafts that run with lubrication. The lip contacts the shaft while the outer case presses into the housing bore, so the seal stays fixed in place and the shaft turns against the lip.

Seals in this size range are common in centrifugal pumps, electric motors, gearboxes, compressors, agitators, and power transmission units. In each case the job is the same: hold oil or grease inside the assembly and block contaminants that would speed up wear on bearings and gears. You also find them in washing equipment and agricultural machinery, where splashes and dust are part of daily operation.

During installation, check that the shaft is free of burrs and marks and that the sealing surface is smooth. A rough surface will reduce lip life. Apply lubricant to the lip before fitting, and keep the seal square to the shaft. Use a tube or shim that presses on the outer case, not on the lip. If the housing has a shoulder, set the seal to the correct depth. When choosing a replacement, consider shaft speed, operating temperature, and the lubricant in use.

To request a quote for code 5289, send us the code along with the shaft, housing, and height dimensions, and the design type if you have it. With that information we can look for an alternative in the same radial shaft seal category or check whether a slightly larger or smaller size is available. It also helps to tell us the equipment where the seal is installed and the brand of the original seal, if you can read it.
