The DBH 5274 radial shaft seal is a lip seal that closes the gap where a rotating shaft exits a housing, keeping lubricant in and contaminants out. With a 50.8 mm shaft diameter, an 80 mm housing bore and a 6.35 mm width, it fits medium-section shafts in pumps, motors, gearboxes and similar equipment.

This seal carries the DBH code 5274. In the size callout, the shaft diameter (d) is 50.8 mm, the housing bore (D) is 80 mm and the height (h) is 6.35 mm. The Ls design is a single lip with a spring, intended for rotating shafts that run with lubrication. The code and the three dimensions are what you need to match the seal to the application.

Seals in this size range appear wherever a shaft turns inside a fixed housing and oil or grease must stay contained: centrifugal pumps, electric motors, reducers, mixers and machine tools. They also suit applications with moderate dust or water exposure, as long as the lip material is compatible with the fluid and the operating temperature.

Selection comes down to three checks: shaft diameter, housing bore and height. The shaft must be free of wear or scoring in the contact area, and the housing clean and free of burrs. The Ls design needs adequate shaft hardness and surface finish to seal properly. Installation with the wrong tool can damage the lip and cause leaks.
