The DBH 8221 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 51 mm shaft diameter, 63 mm housing and 6 mm height, and an Ms design, it is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified with the part number 8221. Its dimensions are: shaft diameter (d) of 51 mm, housing diameter (D) of 63 mm and height (h) of 6.00 mm. The Ms design corresponds to a seal with a single sealing lip and metal body, suitable for rotating shafts with lubrication. These dimensions allow it to be mounted in standard housings and to replace worn seals without modifying the machine.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. In every case, the seal prevents oil or grease leaks and protects bearings and gears from contaminant ingress. It is a wear part that should be checked periodically and replaced at signs of hardening, cuts or loss of elasticity.

To mount the seal correctly, check that the shaft has the proper hardness and roughness, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the application before inserting it. Place the seal perpendicular to the shaft and use a mounting tube that bears on the outer diameter, never on the lip. If the housing shows wear, consider using a seal with greater height or a repair sleeve.
