The DBH 5740 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its Lx design combines a sealing lip with a metal body that press-fits into the cavity. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings must be protected and leaks prevented.

This item is a radial shaft seal from the DBH line, identified by the code 5740. Its dimensions are shaft 88.9 mm, housing 107.88 mm and height 15.87 mm. The Lx design corresponds to a seal with a sealing lip and an outer metal reinforcement, suitable for press-fit mounting in the housing. The lip runs on the shaft with controlled interference that guarantees dynamic sealing.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain drive equipment. It is also found in road and agricultural machinery and in process lines where the shaft rotates at moderate speeds and oil or grease is present. Its function is to retain lubricant inside the assembly and block external contaminants.

To select correctly, verify that the shaft, housing and height dimensions match those of the original seal. The Lx design requires a housing with an adequate surface finish and a shaft free of splines or burrs in the sealing area. During mounting, lubricate the lip and use an installation tool that presses on the outer diameter, never on the lip. Avoid impacts and make sure the seal sits perpendicular to the shaft.
