The DBH 1390 radial shaft seal is a lip seal designed to close off 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 height of 12.00/15.00 mm makes it suitable for gearboxes, pumps and motors where lubricant must be contained and contaminants blocked. MR Accesorios Industriales sells this brand and advises you to choose the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified with 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 of this seal include gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases, the seal serves the function of preventing oil or grease leaks and preventing the entry of water, dust or particles that accelerate the wear of bearings and gears. It is a critical part in the preventive maintenance of industrial machinery.

To install the seal correctly, verify 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 as 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 design with an auxiliary lip. The selection depends on speed, temperature and type of lubricant.
