Measuring just 11.60 mm at the shaft, 22.00 mm at the housing and 7.00 mm in height, the DBH 1403 is a small radial shaft seal built for tight assemblies. It keeps lubricant inside the bearing position and keeps dust and moisture out. MR Industrial Accessories supplies this line and can walk you through picking the right size.

The code breaks down simply: 1403 is the size identifier inside the DBH range, and Lx describes the construction, a sealing lip backed by a spring for rotating shafts. Shaft side 11.60 mm, housing bore 22.00 mm, overall width 7.00 mm. Compare those three figures with the worn part and with the bore itself before you order, since a small mismatch is enough to leave a leak path.

You will usually find a seal this compact in small electric motors, pumps, gearboxes, fans, portable power tools and light transmission units. It normally sits in a cover or crankcase, holding grease or oil on one side and blocking contaminants on the other. Agricultural equipment, washing systems and irrigation hardware also use this size, where grit and damp conditions make a dependable lip important.

Selection comes down to shaft speed, operating temperature and the lubricant in use. The shaft track should be smooth and free of scoring, and the housing needs the right bore and depth. Lubricate the lip before pressing the seal in and use a driver that will not cut or distort it. If the shaft is pitted or has play, replacing the shaft or moving to another size may be the better route.

For an equivalent, send the code 1403 or the three dimensions of the seal you are replacing through WhatsApp or email. We can check options within the same DBH line or among the other brands we supply, keeping the shaft, bore and width matched. If your original seal uses a different lip design, we can point that out as well.
