The DBH 8454 oil seal is a single-lip radial shaft seal designed to retain lubricant and exclude contaminants on rotating shafts. Its A 037 design and dimensions of 14 mm shaft, 50.90 mm housing and 45.80 mm height make it suitable for applications where axial space is ample and a reliable barrier against dust, water and particles is required. It is used in industrial equipment, agricultural machinery and transmissions operating at moderate speeds and controlled temperatures.

This DBH 8454 oil seal has a shaft diameter of 14 mm, a housing diameter of 50.90 mm and a total height of 45.80 mm. The A 037 design corresponds to a radial shaft seal with a sealing lip and metal body, designed to be press-fitted into the housing and seal against the shaft. The combination of dimensions indicates a seal with a compact cross-section but a large outer diameter, suitable for housings with limited shaft space but a wide bore. DBH is a brand that MR carries, with technical support.

Typical applications for this oil seal include gearboxes, pumps, electric motors, rollers and power transmission equipment. It is also used in agricultural machinery, such as seeders and harvesters, where protection against dust and debris is critical. In environments with oil or grease, the sealing lip prevents leaks and maintains internal lubrication. Its design allows it to work at moderate peripheral speeds and withstand small misalignments between shaft and housing.

To correctly select this oil seal, verify that the shaft and housing dimensions match those indicated: 14 mm and 50.90 mm respectively. The 45.80 mm height must be compatible with the housing depth. During assembly, lubricate the lip with the same oil or grease used in the equipment, and insert the seal perpendicularly to avoid damage. It is important that the shaft surface is free of burrs, scratches or excessive wear; otherwise, sealing will not be effective. If the shaft shows wear, consider using a wear sleeve.

If you need an oil seal with equivalent dimensions or a close variant, you can ask us. Sometimes a slightly different outer diameter or height can be adapted to the housing, as long as tolerances are respected. We can also look for alternatives in other brands or materials, such as Viton or nitrile, depending on the temperature and the fluid to be sealed. For that, it helps if you send us a photo of the original seal, the full designation or the dimensions measured with a caliper. That way we can identify the most suitable option without errors.
