When a lubricated shaft needs a reliable barrier against oil loss and outside contamination, the DBH 5992 radial shaft seal is a common choice. It fits a 48.42 mm shaft, an 81 mm housing bore and has a 11.90 mm height. The Lx design indicates a single lip with a spring, which maintains contact on rotating shafts. This seal is typically found in gearboxes, pumps, motors and other power transmission equipment. MR Industrial Accessories supplies this brand and can help you verify the size or find an equivalent.

The DBH 5992 is identified by code 5992. Its key dimensions are: shaft 48.42 mm, housing 81 mm, width 11.90 mm. The Lx design refers to a single-lip seal with a spring, intended for lubricated rotating shafts. The elastomeric lip presses against the shaft while the metal case is held in the housing, so the seal remains stationary and sealing is achieved through continuous radial contact.

Seals of this size are commonly used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. Their main job is to keep oil or grease in and keep contaminants out, protecting bearings from damage. Because it is a wear part, replacement is needed when you notice lubricant leakage, unusual noise at the bearing support, or play and wear around the lip area.

During installation, confirm that the shaft and housing diameters match the specified values. The shaft surface should be free of burrs and grooves, and the housing must be clean and undistorted. Apply lubricant to the lip before pressing the seal in, and use a tool that contacts the metal case, not the lip. If the shaft is worn, a wear sleeve may be an option before replacing the seal.
