The DBH 1170 is a radial shaft seal built to hold lubricant in and keep contaminants out of equipment with rotating shafts. It fits a 100 mm housing bore with a 12.00 mm height, and its A 378 design pairs a flexible sealing lip with a metal case for a firm seat in the bore. You will find this type of seal in pumps, electric motors, gear reducers and similar assemblies, where good sealing is what keeps bearings and gears running.

This seal carries the designation 1170 and comes from the DBH line. Its published dimensions are a housing diameter (D) of 100 mm and a height (h) of 12.00 mm, with the A 378 configuration. The shaft diameter (d) is not fixed by these figures, so confirm it against the manufacturer's data sheet before you commit to a selection. In the A 378 design, a sealing lip works together with a metal case, which suits rotating shafts lubricated with oil or grease.

Where does it belong? Anywhere lubricant has to stay inside and dust, water or particles have to stay outside. That covers centrifugal pumps, electric motors, speed reducers, gearboxes and conveyor rollers, as well as machine tools, process equipment and transmission systems running in dirty or damp conditions. The payoff is straightforward: bearings stay protected and maintenance intervals can be planned instead of forced.

Before installing, check that the 100 mm bore is clean, free of burrs and machined to the right tolerance for a radial shaft seal. Coat the lip with the same oil or grease the equipment uses, then drive the seal in with a tube that presses on the outer diameter so the lip is not damaged. The 12.00 mm height should end up flush or slightly recessed, depending on how the housing is made. If the shaft surface is worn, look at a seal with an auxiliary lip or a repair sleeve.

Need an equivalent? Send the code 1170 or the dimensions of the seal you are replacing, meaning shaft diameter, housing and height. Alternatives from other brands or other designs within the DBH line are also possible. A photo of the part or of the markings on the seal helps us identify it, and our team can match the option to your application and the lubricant in use.
