The DBH 5434 is a radial oil seal from the DBH line, sized for a 15 mm shaft, a 25 mm housing bore and a 6 mm width. It keeps lubricant in and contaminants out where a shaft turns inside a fixed housing, such as in pumps, motors, gearboxes and reducers. Its Lz lip geometry handles moderate shaft speeds and everyday industrial duty. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for your equipment.

Reading the size is straightforward: shaft 15.00 mm, housing 25.00 mm, width 6.00 mm. The 5434 number pins down that exact size in the DBH range. Before you pull an old seal, measure all three values on the shaft and the bore, since a small deviation leads to leakage or a fit that is too tight.

The Lz profile is a single-lip radial seal. It is built for rotating shafts where grease or oil must stay contained while dust, water and particles are blocked from entering. You will find it in centrifugal pumps, electric motors, speed reducers, gearboxes, compressors and transmission units, as well as in agricultural machinery, road equipment and continuous process lines.

Because it is a wear part, replace it when you notice oil weeping, unusual noise or shaft movement. Selection comes down to matching the shaft diameter, housing diameter and height to the equipment; forcing a different size is not advised. The Lz lip suits moderate peripheral speeds and temperatures within the normal range for standard elastomers.

During installation, coat the lip with the same oil or grease the equipment uses, press the seal in square to the shaft and avoid hitting it. If the shaft is worn, a repair sleeve or a seal with an auxiliary lip may be the better route.

For an equivalent, send the full part number plus the shaft, housing and height measurements. With those details we can check alternatives among the brands we carry or point you to the next size up or down, and advise on lip type and elastomer for your application.
