When a rotating shaft needs its lubricant kept in and outside contamination kept out, the DBH 1103 radial shaft seal is the part that does the job. It fits a 107.95 mm shaft, a 152.60 mm housing bore and a 25.40 mm height, and it is built to design A 247. Maintenance and purchasing teams use it on equipment where a failed seal means lost oil, damaged bearings and unplanned downtime. MR Industrial Accessories supplies this brand and helps you confirm the right seal for the application.

The code 1103 identifies this radial shaft seal within the DBH line. Three figures drive the fit: d = 107.95 mm for the shaft, D = 152.60 mm for the housing bore and h = 25.40 mm for the height. Design A 247 is the construction reference: it sets the lip profile and the shape of the outer body. The seal is pressed into the housing and its lip runs against the rotating shaft surface.

You will find this type of seal in gearboxes, pumps, electric motors, rollers and power transmission equipment. These are places where oil or grease is present and has to stay contained, while dust, water and other particles are kept away from bearings and internal parts. Replacing a worn seal is routine industrial maintenance work, and matching the original dimensions is what keeps the assembly running as intended.

Selection starts with the shaft and housing measurements: they have to match the equipment. The height also has to suit the depth of the housing bore. Because design A 247 reflects a particular geometry, compare the profile of the old seal if you do not have the product data in front of you. At installation, coat the lip with lubricant, keep sharp edges away from it, and check that the shaft is free of burrs and heavy wear. A rough shaft surface shortens seal life.

If you are looking for an equivalent, send code 1103 or your current dimensions. MR Industrial Accessories reviews options in the same radial shaft seal category and quotes a match, and can also suggest other designs when the housing allows it. Details such as diameters, height, lubricant type and operating conditions help narrow the proposal.
