The DBH 1390 radial shaft seal is a lip seal designed to stop the passage of oil or grease in equipment with a rotating shaft. Its size of 57.15 mm shaft diameter, 88.90 mm housing and 12.00/15.00 mm height makes it suitable for gearboxes, pumps and motors where lubricant must be contained and contaminants blocked. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified by the designation 1390. Its dimensions are: shaft diameter (d) of 57.15 mm, housing diameter (D) of 88.90 mm and height (h) of 12.00/15.00 mm. The A 114 design corresponds to a single lip configuration with spring, intended to retain lubricant and exclude dust under continuous rotation conditions. The double height indicates that the seal can be mounted in housings with different depths within that range.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. In all cases, the seal serves to prevent oil or grease leaks and to stop the entry of water, dust or particles that accelerate wear on bearings and gears. It is a critical part in the preventive maintenance of industrial machinery.

To mount the seal correctly, check that the shaft has no burrs or excessive wear in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it directly. If the shaft has a deep groove, consider a neighboring size or a design with an auxiliary lip. The selection depends on speed, temperature and type of lubricant.
