The DBH 9111 oil seal is a single-lip radial shaft seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 33 mm shaft diameter, 45 mm housing diameter and 5 mm height make it suitable for compact spaces. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a wear part that should be replaced when leaks or noise appear.

This item is a DBH radial shaft seal, identified by part number 9111. Its dimensions are 33.00 mm shaft diameter (d), 45.00 mm housing diameter (D) and 5.00 mm height (h). The Lx design corresponds to a single sealing lip with spring, without an external dust lip. The lip elastomer and the metal body are bonded by vulcanization, which ensures sealing and mechanical strength. The reduced height of 5 mm allows it to be mounted in housings with little axial space.

It is used in pumps, electric motors, gearboxes, conveyor rollers and power transmission equipment. It also appears in machine tools, compressors and hydraulic systems where oil or grease must be contained and dust or water kept out. It is common in applications with moderate peripheral speeds and temperatures within the usual range of nitrile elastomers. Its main function is to protect the bearings and extend the service life of the assembly.

For mounting, check that the shaft has a polished surface, free of burrs and scratches, with suitable hardness and roughness. The housing must be clean and undamaged; the seal is pressed in with a flat tool that bears on the metal edge, never on the lip. Lubricate the lip with the same service oil or grease before installing. Make sure the lip faces the side of the fluid to be retained and that the spring is correctly seated.

If you need an equivalent or a nearby size, send us part number 9111 or the dimensions 33 x 45 x 5 mm via WhatsApp. We can look for alternatives in other brands or materials. It is also advisable to check the condition of the shaft: if it shows wear, a seal of the same size may not seal properly and a repair sleeve or a seal with an offset lip may be necessary. Tell us your application and we will advise you.
