The DBH 8120 radial shaft seal is a rotary shaft seal that prevents oil or grease leaks and blocks dust and water ingress in gearboxes, pumps and motors. Its Mx-R design and dimensions of 28.58 mm shaft, 41.20 mm housing and 6.20 mm height make it suitable for equipment where axial space is limited. MR Accesorios Industriales supplies it as part of its seals and oil seals line.

This DBH 8120 seal has a shaft diameter of 28.58 mm, a housing diameter of 41.20 mm and a height of 6.20 mm. The Mx-R design indicates a configuration with a sealing lip and metal body, intended for rotating shafts with permanent lubrication. The 8120 designation identifies the exact size within the DBH line and allows replacing the seal without modifying the housing.

It is used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment where oil or grease must be retained and contaminants excluded. It also appears in agricultural and industrial applications with 28.58 mm shafts, where the seal protects bearings and prevents premature wear due to lack of lubricant or particle ingress.

For installation, check that the shaft has no burrs or splines and that the sealing surface is polished. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The housing must be clean and free of deformation; if the previous seal failed, check bearing play and concentricity. The 6.20 mm height requires a seat that does not compress the lip.

If you need a nearby size or an equivalent, send us the 8120 code and the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we search the DBH line or another available brand. We can also advise you if the Mx-R design does not match the original and another lip configuration needs to be evaluated.
