The DBH 8478 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants in equipment with a rotating shaft. Because of its dimensions of 145 mm shaft, 175 mm housing and 13 mm height, it is mounted in gearboxes, pumps and medium-to-large reducers. MR Accesorios Industriales sells this brand and advises you so you choose the right seal for your application.

This item is a DBH radial shaft seal identified with part number 8478. Its dimensions are 145 mm shaft diameter, 175 mm housing diameter and 13.00 mm height. The Kx-Bidi design corresponds to a double-lip configuration with reinforcement, intended to contain lubricant from both sides of the seal. The elastomer and the internal spring work on the shaft to maintain contact and compensate for small misalignments.

Seals of this size are used in equipment where the shaft rotates at moderate speeds and oil or grease is present. They are commonly found in gearboxes, centrifugal pumps, mixers, mills and conveyors. They are also fitted in large electric motors and in older machines where the housing already shows wear from use. In every case, the function is the same: retain the lubricant and block dust.

To select the right seal, verify that the shaft diameter, housing diameter and height match those of the DBH 8478. Check the condition of the shaft surface: if it has a groove or deep scratches, the lip will not seal properly and it is best to repair it or use a sleeve. During installation, lubricate the lip with the same grease or oil used in the equipment and tap the seal in evenly, without tilting it. If the housing has burrs, clean them before inserting it.
