The DBH 5303 radial shaft seal is a lip seal designed to retain lubricant and keep contaminants out of rotating shafts. Its designation 5303 corresponds to a standard size of 40 mm shaft diameter, 62 mm housing bore and 13 mm height, with an Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with oil or grease. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by the code 5303. Its dimensions are 40 mm shaft diameter (d), 62 mm housing bore diameter (D) and 13.00 mm height (h). The Lx design indicates a single lip configuration with a spring, suitable for retaining lubricant in one direction of rotation. The sealing lip runs on the shaft and the outer case is press-fitted into the housing. It is a common replacement part in equipment with rotary motion.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In all cases, its function is to keep oil or grease inside the assembly and block dust, water or particles that could damage the bearings. It is also used in power transmission equipment where the shaft rotates continuously and the goal is to reduce leaks and maintenance.

To install a seal such as the 5303, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and press evenly until it seats at the bottom. If the shaft shows a marked track, consider a nearby size or a repair sleeve. Selection depends on speed, temperature and the type of fluid.
