The DBH 1101 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants in rotating equipment. It is installed in cylindrical housings and works on rotating shafts, where sealing depends on the fit between the lip and the shaft surface. It is a wear part that should be replaced when oil leakage, dust ingress or bearing noise appears. MR Accesorios Industriales supplies this brand and advises you so you choose the correct size.

This DBH 1101 seal has a shaft diameter of 121.08 mm, a housing bore of 160.22 mm and a height of 26.29 mm. The A 222 design corresponds to a single-lip seal with a metal case and sealing lip, intended for rotating shafts with lubrication. The manufacturer's nomenclature identifies the exact size: any variation in the shaft or housing diameter changes the fit and the effectiveness of the seal. Therefore, verify the dimensions before replacing.

Radial shaft seals such as this one are used in gearboxes, pumps, electric motors, rollers and power transmission equipment. Their function is to retain the oil or grease inside the assembly and block dust, water or particles that could damage the bearings. In industrial, food or process plants, a seal in good condition extends the service life of the bearings and prevents downtime due to leaks.

To install a radial shaft seal, the shaft must be clean, free of burrs or marks, and the housing free of deformation. It is recommended to lubricate the lip before inserting it and to use an installation tube that presses on the case, never on the lip. Shaft speed, working temperature and the type of lubricant influence the selection. If the original seal fails prematurely, check the shaft roughness and the concentricity of the housing.

If you need an equivalent size or a close variant, send us the part number 1101 or the dimensions of the old seal: shaft diameter, housing bore and height. With that data we search the DBH line for the option that fits best. We can also advise you if the A 222 design is not suitable for your application and a different lip profile or material is needed.
