The DBH 1033 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With a shaft diameter of 39.42 mm, a housing diameter of 70.40 mm and a height of 6.30/16.38 mm, it fits assemblies where axial space is tight but a firm lip contact is needed. It is commonly found in gearboxes, pumps, electric motors and transmissions. MR Industrial Accessories supplies this brand and helps you select the right seal for the application.

This seal belongs to the DBH line and carries the code 1033. Its key dimensions are shaft 39.42 mm, housing 70.40 mm and height 6.30/16.38 mm. The A 003 design is a single-lip configuration with a metal body and elastomer, made for press fitting into a cylindrical housing. The dual height figure reflects a stepped profile: a 6.30 mm section that seats in the housing and a lip that extends to 16.38 mm, which helps maintain contact on the shaft when minor misalignment is present.

Typical uses include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In these applications the seal does two jobs: it stops oil or grease from escaping and it blocks dust, water or particles that would speed up wear on bearings and gears. The near-40 mm shaft size makes it common in medium-sized machines such as agitators, conveyors and continuous process equipment.

When selecting and installing this seal, confirm that the shaft and housing diameters match the values above. The shaft surface should be ground and free of splines or burrs; excessive roughness will shorten lip life. Lubricate the lip with the same oil or grease used in the equipment, and make sure the housing is clean and free of ridges. Press the seal in with a proper mounting tube; never strike the elastomer directly. If the shaft is worn, consider a repair sleeve or an alternative size.

To request a quote for a DBH 1033 or an equivalent, send the full code, the shaft and housing dimensions, and a photo of the old seal if possible. With that information we can search for an alternative within the same brand or another line we supply. We can also advise on lip type, elastomer material and working temperature so the replacement performs reliably.
