The DBH 6887 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With dimensions of 48.70 mm shaft, 58.00 mm housing and a height of 5.50/8.50 mm, it is used in gearboxes, pumps, electric motors and power transmission equipment. Its A 131 design combines a sealing lip with a metal body that gives it rigidity and centering.

This DBH 6887 oil seal has a 48.70 mm shaft diameter, a 58.00 mm housing diameter and a height of 5.50/8.50 mm. The A 131 design corresponds to a single-lip seal with metal case and spring, intended for rotating shafts with lubrication. The double height dimension indicates that the lip can flex without losing contact, which helps compensate for small misalignments or shaft eccentricity. It is a common replacement part in equipment where oil or grease leaks must be prevented.

It is used in gearboxes, reducers, centrifugal pumps, electric motors, compressors and conveyor rollers. It also appears in machine tools, washing equipment and transmission systems where the shaft rotates inside a fixed housing. In all these cases, the seal separates the lubricant from the environment and protects the bearings or bushings from external contamination. It is a wear part: it should be checked when leaks appear or when the equipment accumulates many hours of operation.

To install it, verify that the shaft is clean, free of burrs or marks, and that the sealing surface has the proper roughness. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a tube or press that bears on the outer edge, never on the lip. The housing must be clean and free of impacts. If the shaft shows wear, consider a neighboring size or a seal with the lip in another position. The selection depends on speed, temperature and the type of lubricant.

If you need an equivalent or a close size, send us the code 6887 or the shaft, housing and height dimensions. The equipment code or a photo of the old seal also works. With that data we look for alternatives in the same series or in equivalent brands, always respecting the mounting dimensions. If space allows, we can offer you a seal with a different height or design that fulfills the same function.
