The DBH 8283 is a radial shaft seal from the DBH brand. It keeps lubricant in and contaminants out of rotating equipment. The seal fits a shaft of 18 mm, a housing of 26 mm, and has a stepped height of 6.00/9.50 mm, so it suits spaces with a shoulder. As a wear part, it should be replaced when leaks or noise appear. MR Industrial Accessories supplies this brand and helps you confirm the correct size.

This seal carries the code 8283 and the A 090 design, which means a single-piece lip seal with a rubber lip and a spring, intended for rotating shafts that run with lubrication. The dimensions are shaft 18 mm, housing 26 mm, and height 6.00/9.50 mm. That double height indicates the sealing lip sits in the 6 mm section, while the 9.50 mm outer shoulder helps with press fitting. Always check these figures against the manufacturer's data sheet before ordering.

Typical uses include gearboxes, pumps, electric motors, transmission shafts, and process equipment. The seal does two jobs: it holds the oil or grease that lubricates the bearing, and it blocks dust, water, or chips from entering. In dirty or wet conditions, a healthy seal helps bearings and gears last longer. It also fits applications where axial space is tight and a compact seal is needed.

During installation, inspect the shaft for burrs or wear and make sure the sealing surface is clean. Apply the same oil used in the equipment to the lip before sliding the seal into place. The housing must be machined to the right tolerance for a press fit. Use a tube with an outer diameter close to that of the seal and tap it in evenly to avoid deforming the seal. If the shaft has a deep groove, an auxiliary lip design may be a better choice. Speed, temperature, and lubricant type all affect the final selection.
