The DBH 9220 oil seal is a lip-type radial shaft seal designed to retain lubricant and exclude contaminants on rotating shafts. Thanks to its dimensions — 40 mm shaft, 90 mm housing and 10 mm height — it is used in gearboxes, pumps and medium-size power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the right seal according to the type of lubricant, speed and shaft finish.

The DBH 9220 is a radial shaft seal with the following dimensions: shaft diameter 40 mm, housing diameter 90 mm and height 10 mm. The Kz design corresponds to a single-lip configuration with spring, suitable for rotating shafts lubricated with oil or grease. The sealing lip runs on the shaft and the outer diameter is press-fitted into the housing, so the seal closes the passage of lubricant to the outside and blocks the entry of dust, water or particles.

This type of seal appears in gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. It is also used in machine tools and in food industry equipment where the lubricant must be contained and product contamination avoided. Its 40 x 90 x 10 mm size is common on medium-diameter shafts with thick-wall housings.

To install it, check that the shaft has adequate hardness and roughness, with no burrs or marks that could damage the lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with an installation tool that rests on the outer diameter. If the shaft shows wear, consider a nearby size or a seal with an offset lip. The selection depends on peripheral speed, temperature and the type of lubricant.

With that data we check nearby sizes and alternatives from other brands that MR supplies, always respecting the mounting dimensions.
