The DBH 8424 oil seal is a single-lip radial shaft seal designed to be mounted on rotating shafts to prevent lubricant leaks and the ingress of dust and contaminants. Due to its dimensions, it is used in large equipment where the housing space is ample and a reliable barrier is required. MR Accesorios Industriales carries this official brand so you can resolve replacements with standardized dimensions.

This item is a DBH radial shaft seal, identified by the designation 8424. Its main dimensions are: shaft diameter 127 mm, housing diameter 192 mm and overall height 14.00/18.50 mm. The A 085 design corresponds to a profile with a sealing lip and metal body, suitable for retaining oil or grease under rotating conditions. The variable height indicates that the mounting section can adapt to housings with a shoulder or step.

Seals of this size are used in heavy equipment: high-power gearboxes, mills, process centrifugal pumps, industrial mixers and mining or cement machinery. They also appear on induced draft fan shafts and kiln rollers. Their function is to protect bearings and gears from premature wear, retaining lubricant and blocking the entry of abrasive particles.

For correct installation, verify that the shaft has the appropriate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip with the same grease or oil used in the equipment before inserting it. Selection must consider peripheral speed, operating temperature and the chemical compatibility of the elastomer with the fluid. If the original seal has a different height, consult the manufacturer's product page to confirm interchangeability.
