The DBH 5489 is a radial shaft seal built to hold oil or grease inside a housing and keep contaminants out where a shaft turns. Its three key measurements are a 49.20 mm shaft diameter, a 63.55 mm bore diameter and a 7.14 mm width, which places it in gearboxes, pumps, motors and transmission assemblies. The Lx configuration pairs a primary sealing lip with a secondary dust lip that shields the contact zone. MR Industrial Accessories supplies this brand within its seals line and can help you confirm the correct choice for your equipment.

Reading the reference is straightforward: 5489 is the designation, and the three figures that follow describe the seat. Shaft diameter (d) is 49.20 mm, housing diameter (D) is 63.55 mm and height (h) is 7.14 mm. The Lx code tells you the seal carries a main lip plus an auxiliary exclusion lip, which adds a barrier against dust and dirt. Lip and body material should always be verified against the manufacturer's product page before ordering.

This seal fits the classic arrangement of a rotating shaft passing through a stationary housing. You will find it in gearboxes, centrifugal pumps, electric motors, compressors and gear transmissions, as well as in power transmission equipment and agricultural or industrial machinery. The compact envelope and the second lip suit locations where dust or humidity is present at moderate levels.

Installation habits matter as much as the part itself. Confirm the shaft hardness and surface roughness are within spec, and make sure the bore is clean and free of burrs. Coat the lip with the same oil or grease the equipment runs on before pressing the seal in. Drive it with a tube or socket that bears on the outer diameter, never on the lip. A worn shaft may call for a repair sleeve or a different size. Shaft-to-housing alignment has a direct effect on how long the seal lasts.
