The DBH 9807/85 radial shaft seal is a lip seal designed to close off lubricant and prevent contaminants from entering rotating shafts. With dimensions of 25 mm shaft diameter, 34 mm housing and 5 mm height, it is press-fitted into crankcases, covers and housings. It is a wear part that should be replaced when oil loss or shaft play appears. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

This item is a radial shaft seal from the DBH brand, identified with the designation 9807/85. Its dimensions are: shaft diameter (d) 25 mm, housing diameter (D) 34 mm and height (h) 5.00 mm. The Lz design corresponds to a single sealing lip with spring, suitable for rotating shafts with lubrication. The 9807/85 nomenclature groups a series of seals with different combinations of dimensions; in this case, the product page confirms the values indicated. It is a standard component within the line of seals and oil seals that MR distributes.

Typical applications for a seal such as the 9807/85 include gearboxes, electric motors, centrifugal pumps, reducers and transmission equipment. In all cases, its function is to retain the oil or grease inside the assembly and block dust, water or particles that could damage the bearings. It is also used on fan shafts, compressors and machine tools where axial space is limited, since its 5 mm height allows it to be mounted in shallow housings.

To correctly select a seal, check that the shaft and housing dimensions match those of the component to be replaced. The shaft surface must be ground and free of grooves; excessive roughness accelerates lip wear. The housing must have an entry chamfer so as not to damage the seal during installation. The 5.00 mm height determines the housing depth: if the space is greater, a shim may be necessary. The Lz design supports moderate peripheral speeds and low pressures.

If you need a seal with nearby dimensions or an equivalent from another brand, the most practical thing is to send us part number 9807/85 or the exact dimensions (25 x 34 x 5 mm) by WhatsApp. With that data we can look for an alternative within the same series or another line that fulfills the function. We can also advise you on the type of lip, the elastomer material and the spring, depending on the fluid and the working temperature. We do not improvise: we confirm every dimension against the manufacturer's product page before quoting.
