The DBH 1385Tef radial shaft seal is a lip seal designed to be mounted on a 50 mm shaft and retain lubricant inside a housing, preventing leaks and the ingress of contaminants. It is used in gearboxes, pumps, electric motors and power transmission equipment where the shaft rotates inside a housing. Its design A corresponds to a single-lip configuration with spring, suitable for general dynamic sealing applications. MR Accesorios Industriales supplies this official brand and advises you so you choose the correct size.

This item is a radial shaft seal from the DBH line, identified with the code 1385Tef. According to the product page data, it is intended for a shaft of 50 mm in diameter. Design A indicates a single-lip construction with spring, oriented to rotating shafts with lubrication. The housing and height values are not valid, so they are confirmed against the manufacturer's data sheet before quoting. Do not make assembly decisions without verifying those two dimensions on your equipment's drawing.

Typical applications of a 50 mm shaft oil seal include gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain transmission equipment. In all these cases, the oil seal prevents oil or grease from escaping the housing and dust or water from entering the bearing or gear. It is also used in machine tools, compressors and continuous process equipment, where a small leak can affect lubrication and shorten the service life of internal components.

To correctly select a radial shaft seal, take into account the shaft diameter, the housing diameter and depth, the type of lubricant, the working temperature and the peripheral speed of the shaft. Design A with spring is suitable for rotating shafts with abundant lubrication; if there is internal pressure or heavy contamination, another design may be required. Assembly must be done with the proper tool, without striking the lip, and with the shaft clean and free of burrs. Poor installation is the most common cause of premature leaks.
