The DBH 9285 oil seal is a single-lip radial shaft seal designed to retain oil or grease and exclude contaminants on rotating shafts. Its A 103-R-H design combines a sealing lip with a dust lip, which improves protection in dusty or dirty environments. It is press-fitted into the housing and runs on the shaft, creating a reliable dynamic barrier. It is a key part for maintaining lubrication and preventing leaks in industrial equipment.

This oil seal has a shaft diameter of 44.20 mm, a housing diameter of 71.40 mm and an overall height that ranges from 10.00 to 16.50 mm depending on the lip position. The A 103-R-H design indicates a configuration with a main lip and a secondary exclusion lip, mounted on a metal body with a coating. The designation 9285 corresponds to the standard size within the DBH line. It is a precision component that requires careful handling during installation so as not to damage the sealing lip.

It is used in gearboxes, pumps, electric motors, transmission shafts and continuous process equipment. It is common in applications exposed to dust, chips or water, thanks to its dust lip. It is also used in agricultural machinery, conveyors and hydraulic systems that need to contain lubricant and prevent the ingress of particles. Its size makes it suitable for medium-sized equipment, where radial space is limited but high reliability is required.

To select the correct oil seal, verify that the shaft diameter is within the recommended tolerance, with a surface roughness suitable for dynamic sealing. The housing must have an entry chamfer and a depth that allows the full height of the oil seal to be seated without interference. During installation, lubricate the lip with the same oil or grease used in service and use an installation tool that presses on the outer diameter, never on the lip. Avoid striking the seal directly.
