The DBH 1033 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 39.42 mm shaft diameter, 70.40 mm housing and height of 6.30/16.38 mm place it in equipment with limited axial space but with the need for a firm contact lip. It is used in gearboxes, pumps, electric motors and transmissions where oil or grease must stay inside the assembly. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right oil seal for your application.

This item is a radial shaft seal from the DBH line, identified by the code 1033. Its main attributes are: shaft diameter 39.42 mm, housing diameter 70.40 mm and height 6.30/16.38 mm. The A 003 design corresponds to a single lip configuration with metal body and elastomer, intended for press fitting into a cylindrical housing. The double height indicates that the seal has a stepped profile: a 6.30 mm section that enters the housing and a lip that protrudes up to 16.38 mm, which allows slight misalignments to be compensated and contact to be maintained on the shaft.

Typical applications for this oil seal include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In all these cases, the seal performs two functions: to prevent oil or grease from leaking to the outside and to block the entry of dust, water or particles that accelerate the wear of bearings and gears. Because of its shaft size close to 40 mm, it is common in medium-sized equipment, such as agitators, conveyors and continuous process machinery.

To correctly select and mount this oil seal, check that the shaft and housing diameters match the values indicated. The shaft surface must be ground and free of splines or burrs; excessive roughness accelerates lip wear. Before mounting, lubricate the lip with the same oil or grease used in the equipment and make sure the housing is clean and free of ridges. The seal is pressed in with a suitable mounting tube, never by striking the elastomer directly. If the shaft shows wear, consider a repair sleeve or an alternative size.

If you need an oil seal equivalent to the DBH 1033 or a neighbouring size, the most practical thing is to send us the full code, the shaft and housing dimensions, and a photo of the old seal if possible. With that data we can look for an alternative within the same brand or another line we supply. We can also advise you on the lip type, the elastomer material and the working temperature, so that the replacement is reliable and does not fail in the short term.

At MR Accesorios Industriales we supply the DBH brand as part of our seals and oil seals line. If this oil seal is for equipment in operation, do not wait for the leak to get worse: send the code 1033 on WhatsApp and we will quote the part or its equivalent. Our technical team reviews every enquiry with the application data so that you receive the correct oil seal and not an approximation.
