The DBH 9821 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles. With dimensions of 30 mm shaft, 45 mm housing and 16 mm height, it is press-fitted into crankcases, covers and gearboxes. MR Accesorios Industriales carries this official brand and advises you on choosing the correct oil seal for your application.

The DBH 9821 is an oil seal with an A 053 design, with the following dimensions: shaft diameter 30 mm, housing diameter 45 mm and height 16 mm. These dimensions correspond to the 9821 designation and allow it to be identified without ambiguity. The sealing lip works against the rotating shaft, while the outer diameter fits into the fixed housing. The 16 mm height provides a wide support surface for installation.

It is used in equipment with rotating shafts that require oil or grease containment, such as gearboxes, pumps, electric motors, mixers and conveyors. It also appears in applications exposed to dust or splashes. It is common in industrial maintenance and in the repair of agricultural or process machinery. Its radial design makes it suitable for moderate speeds and continuous operating conditions.

To select the correct oil seal, check that the shaft, housing and height dimensions match those of your equipment's housing and shaft. Check the condition of the shaft surface: it must not have grooves or wear that damage the lip. During installation, lubricate the lip and use an installation tool so as not to deform it. Shaft eccentricity and play must be within tolerances to prevent premature leaks.
