The DBH 5231 is a radial shaft seal that sits in the housing bore and rides against the turning shaft, holding lubricant in and keeping dust, water and particles out. Its dimensions are 45.00 mm shaft, 65.00 mm housing and 8.00 mm height, with the Lx lip design. You will find this size in gearboxes, pumps, electric motors and power transmission equipment. MR supplies this brand and can help you confirm the right oil seal for the job.

The code 5231 belongs to the DBH line of radial shaft seals. Reading the size is straightforward: shaft diameter (d) 45.00 mm, housing diameter (D) 65.00 mm, height (h) 8.00 mm. The Lx designation describes a lip seal with a standard configuration for rotating shafts. Inside, the elastomer lip and the spring work together to stay in contact with the shaft and absorb small misalignments. It is a routine replacement item in industrial maintenance.

Seals in this size range show up in gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the job is the same: keep oil or grease where it belongs and stop outside contaminants from getting in. Fan, mixer and conveyor shafts also use them, since a failed seal leads to lubricant loss and accelerated wear on bearings and bushings.

Installation calls for a clean shaft and housing, free of burrs and marks, and a light film of lubricant on the lip before you press the seal in. It has to go in square to the shaft, without hammer blows that distort the casing. When selecting a replacement, rotation speed, operating temperature and lubricant type all matter, because they drive the choice of lip material and spring. If the shaft itself is worn, a repair sleeve is worth considering before the new seal goes on.

If you need an equivalent or another size, send the full code, the shaft, housing and height dimensions, plus a photo or sample of the original seal. With that we can search the DBH line or other brands we carry. We can also tell you whether the Lx design fits your equipment or whether another lip or casing configuration should be evaluated.
