The DBH 8424 oil seal is a single-lip radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With a 127 mm shaft diameter, 192 mm housing bore and 14.00/18.50 mm height, it fits large assemblies where a dependable barrier is needed. MR Industrial Accessories supplies this brand to help you match standardized dimensions for replacement.

This seal carries the DBH designation 8424. Its key dimensions are shaft 127 mm, housing 192 mm and overall height 14.00/18.50 mm. The A 085 profile combines a sealing lip with a metal case, making it suitable for oil or grease retention in rotating service. The two height values indicate that the mounting section can accommodate a housing with a shoulder or step.

Seals in this size range appear in heavy-duty applications: high-power gearboxes, mills, process centrifugal pumps, industrial mixers, and mining or cement machinery. They are also found on induced draft fan shafts and kiln rollers. Their role is to protect bearings and gears from premature wear by holding lubricant in place and blocking abrasive particles.

During installation, confirm that the shaft has the correct hardness and surface finish, and that the housing is clean and free of burrs. Apply the same oil or grease used in the equipment to the lip before pressing the seal into position. When selecting a replacement, consider peripheral speed, operating temperature and the elastomer's chemical compatibility with the fluid. If the original seal has a different height, check the manufacturer's product page to confirm interchangeability.

For an equivalent seal, send the complete part number, the shaft, housing and height dimensions, and a photo of the old seal. With that information we can search for an alternative within the same series or from another brand we carry. We can also help you choose the right lip type and material for your application.
