When a rotating shaft needs a dependable barrier against lubricant loss and outside contamination, the DBH 8454 oil seal is built for that job. It is a single-lip radial shaft seal with the A 037 design, sized for a 14 mm shaft, a 50.90 mm housing and a 45.80 mm height. Those proportions suit equipment where the bore is wide but the shaft is small, and where a solid seal against dust, water and particles matters more than saving axial room.

Reading the dimensions is the fastest way to check fit: shaft 14 mm, housing 50.90 mm, width 45.80 mm. The A 037 designation describes a radial shaft seal with a sealing lip and a metal body, press-fitted into the housing and running against the shaft. The large outside diameter paired with a small bore gives a compact cross-section, which is useful when the housing has plenty of room around the bore but very little space along the shaft.

You will find this seal in gearboxes, pumps, electric motors, rollers and other power transmission assemblies. Agricultural equipment such as seeders and harvesters also uses it, since dust and debris are constant there. In oil- or grease-lubricated parts, the lip holds the lubricant in and keeps contaminants out. It handles moderate peripheral speeds and tolerates minor misalignment between shaft and housing.

Before ordering, confirm that the shaft measures 14 mm and the housing bore 50.90 mm, and that the 45.80 mm height fits the housing depth. Lubricate the lip with the same oil or grease the equipment uses, then press the seal in squarely so the lip is not damaged. The shaft surface should be free of burrs, scratches and heavy wear, or the lip cannot seal properly. If the shaft is worn, a wear sleeve is an option worth considering.

If you need the same dimensions from another brand or a close variant, we can help. A slightly different outer diameter or height can sometimes be adapted to the housing as long as tolerances are respected. Alternatives in other materials, such as Viton or nitrile, may suit the temperature and the fluid being sealed. A photo of the original seal, the full designation or caliper measurements all help us identify the right option.
