The DBH 5983 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 47.63 mm shaft, a 77.75 mm housing and has a 12.70 mm height, and its Mz design uses a single sealing lip with a metal case for press-fit installation.

With a shaft diameter of 47.63 mm, a housing bore of 77.75 mm and a 12.70 mm height, the DBH 5983 matches common industrial housings. The Mz designation refers to a lip seal with a metal outer case, meant to be pressed into a cylindrical housing. The 5983 code identifies this size within the DBH line, so keeping those three dimensions exact is what ensures a proper fit and avoids early leaks.

You will find this seal in centrifugal pumps, gear reducers, gearboxes, electric motors, compressors, and belt or chain drives. Its job is to hold oil or grease inside the assembly while blocking dust, water and particles that would otherwise speed up wear on bearings and gears. For preventive maintenance on rotating machinery, it is a key item to check and replace when needed.

When selecting a replacement, confirm that the shaft and housing dimensions match the equipment. The shaft diameter should fall within the tolerance recommended for the lip, and the housing surface finish should suit press-fit mounting. Lubricate the lip with the same oil used in the system before installation, and use a proper mounting tool to avoid damaging the seal. If the shaft is worn, consider repairing it or using a seal with an auxiliary lip.
