The DBH 8890 radial shaft seal is a lip seal designed to keep lubricant in and contaminants out of rotating shafts. Its dimensions of 40 mm shaft diameter, 52 mm housing diameter and 10 mm height place it in a medium-size application, common in industrial equipment. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your equipment.

This item is a radial shaft seal from the DBH line, identified by the code 8890. Its nominal dimensions are 40 mm shaft diameter (d), 52 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip configuration with spring, intended to retain lubricant in one direction and keep dirt out of the bearing or housing. It is a common replacement part in gearboxes, pumps and electric motors.

Typical applications for a seal of this size include transmission shafts, machine tool bearings, centrifugal pumps, speed reducers and continuous process equipment. In all cases it serves to retain oil or grease inside the assembly and block dust, wash water or particles that shorten bearing life. It is also used in agricultural equipment and in conveyors with exposed rotating shafts.

To install a radial shaft seal, check that the shaft diameter is within the recommended tolerance and that the contact surface has no burrs or marks that could damage the lip. The housing must be clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and use an installation tool that presses on the outer edge, never on the lip. If the shaft shows wear, consider a seal with an auxiliary lip.
