The DBH 8489/85 oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and stop dust, water or chips from entering. With a 45 mm shaft diameter, 62 mm housing diameter and 8 mm height, it is a common size in gearboxes, pumps and electric motors. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a DBH radial shaft seal with designation 8489/85, with the following dimensions: shaft diameter 45 mm, housing diameter 62 mm and height 8.00 mm. The indicated design is Lt, which corresponds to a single sealing lip with an outer metal case. The rubber lip runs on the rotating shaft and the outer diameter is press-fitted into the bore. It is a standard replacement part, not a custom-made component.

Seals of this size are used in equipment with a rotating shaft where oil or grease must be separated from the environment: gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers and machine tools. They also appear in applications where the seal protects bearings from dust and moisture, extending the service life of the assembly. In any case, selection depends on the type of lubricant, speed and operating temperature.

To install a radial shaft seal, the shaft must be polished, free of burrs and lathe marks, and the housing clean and free of dents. It is advisable to lubricate the lip before inserting it and to use an installation tool that presses on the outer diameter, never on the lip. If the shaft shows wear on the sealing surface, consider a repair sleeve or a nearby size. The 8.00 mm height allows it to fit in cavities where a wider seal will not go.

If you need an equivalent or a nearby size, send us the part number 8489/85 together with the shaft, housing and height dimensions, and the type of lubricant the equipment uses. With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the seal is mounted with a bearing or a bushing and you need to replace the complete assembly.
