The DBH 1120 oil seal is a lip seal designed to retain lubricant and block dust, water or particles at the point where a shaft passes through a housing. With a 41 mm shaft diameter, 59 mm housing diameter and 11 mm height, and design A 248, it is a common size in power transmission equipment and industrial machinery. MR Accesorios Industriales carries this official brand and advises you on choosing the right seal.

This item is a DBH radial shaft seal with designation 1120. Its dimensions are 41 mm shaft diameter (d), 59 mm housing diameter (D) and 11 mm height (h), with design A 248. The sealing lip runs on the rotating shaft and the outer diameter fits into the housing with an interference fit, so the assembly seals without leaking oil or grease outward and without letting contaminants in.

It is used in gearboxes, pumps, electric motors, rollers, mixers and power transmission equipment in general. It also appears in agricultural machinery, conveyors and process lines where shafts rotate inside a lubricated housing. It is a wear part: when the lip hardens, gets cut or the spring loses tension, lubricant loss or dirt ingress begins to appear.

For installation, check that the shaft has no burrs, scratches or wear on the sealing surface, and that the housing is clean and free of dents. Lubricate the lip before inserting it and fit the seal perpendicular, without tilting it, using a tube or spacer that presses on the outer edge. If the shaft shows a marked groove, it is worth evaluating a neighboring size or a wear sleeve before installing the new seal.

If you need an equivalent or a close size, send us part number 1120 along with the shaft, housing and height dimensions, the type of lubricant and the operating temperature. With that data we review alternatives within the DBH line and other brands we carry, and we confirm which option fits without modifying the housing. We can also verify against the manufacturer's data sheet whether design A 248 is the right one for your application.

MR Accesorios Industriales carries the DBH brand as an official brand.
