The DBH 9057 radial shaft seal is a lip seal designed for rotating shafts with a 10 mm diameter, a 30 mm housing and a 7 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in small electric motors, pumps, gearboxes and power transmission equipment operating at moderate speeds.

This item is identified by the designation 9057 and corresponds to a seal of Lx design, with a single sealing lip and metal case. Its dimensions are shaft (d) 10 mm, housing (D) 30 mm and height (h) 7.00 mm. The Lx design indicates a standard configuration for rotating shafts, with a lip that runs on the shaft surface and an outer case that is press-fitted into the housing. It is important to respect these dimensions when replacing the part.

Typical applications for this seal include low-power electric motors, small centrifugal pumps, speed reducers, gearboxes and belt or chain drive equipment. It is also used in machine tools, compressors and lubrication systems where oil or grease must be contained and bearings protected from the environment. Its compact size makes it suitable for tight spaces.

To correctly select a seal, verify that the shaft diameter, housing diameter and height match the original dimensions. The shaft surface must be clean, free of burrs or deep marks, and lubricated before assembly. The seal is inserted with a suitable tool, applying uniform pressure on the outer circumference to prevent deformation. If the shaft shows wear, consider using a seal with the lip in a different position or consult our technical team.
