The DBH 5603 oil seal is a single-lip radial shaft seal designed for a 38 mm shaft and a 50 mm housing, with a height of 10.00/16.00 mm. It is used to retain lubricant and exclude contaminants in gearboxes, pumps, electric motors and power transmission equipment. Its A 204 design and the DBH brand ensure reliable sealing under continuous rotation. MR Accesorios Industriales carries this brand as part of its seals and oil seals line.

The DBH 5603 is a single-lip radial shaft seal with the following dimensions: shaft diameter 38 mm, housing diameter 50 mm and height 10.00/16.00 mm. The A 204 design corresponds to a standard configuration with a sealing lip and metal case. This type of oil seal is press-fitted into the housing and seals against the shaft by means of a flexible lip, preventing oil or grease leaks and the ingress of dust or water. It is suitable for rotating shafts at moderate speeds and temperatures within the usual range of nitrile elastomers.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors, transmission shafts and process equipment in general. In industry, it is found in production lines, pumping equipment, conveyors and agricultural machinery. Its main function is to protect bearings and gears by retaining lubricant and blocking external contamination, which extends component service life and reduces maintenance downtime.

For correct installation, check that the shaft surface is smooth and free of burrs, with adequate hardness to prevent premature lip wear. The housing must be clean and undamaged; it is recommended to lubricate the lip before inserting the seal and to use an installation tool that applies uniform pressure on the outer diameter. Seal selection must take into account rotation speed, operating temperature and the type of fluid to be retained. If the original seal shows wear, replace it with one of the same dimensions and design.
