The DBH 9993 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 20 mm shaft, 30 mm housing and 7 mm height, it is a compact size widely used in low and medium power equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified by part number 9993. Its dimensions are 20.00 mm shaft diameter (d), 30.00 mm housing diameter (D) and 7.00 mm height (h). The Mx design corresponds to the standard single-lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip runs on the shaft and the metal case is fixed in the housing, sealing by interference.

Typical applications for a seal of this size include small gearboxes, electric motors, centrifugal pumps, compressors, fans and transmission equipment. It is also used in machine tools, washing equipment and conveyor systems where bearings or bushings must be protected from the entry of contaminants. Because of its compact size, it is common in equipment where radial space is limited and reliable sealing is required.

To install it, verify that the shaft is clean, free of burrs or marks, and that the sealing surface has the appropriate hardness and roughness. Lubricate the lip before inserting it and install the seal with a mounting tube that bears on the case, never on the lip. If the shaft shows wear, consider a seal with an auxiliary lip. The selection depends on the speed, temperature and type of lubricant of the equipment.
