Part number 6738 belongs to the DBH line of radial shaft seals. It seats in the housing and rides against the turning shaft, holding lubricant in and keeping dust, water and particles out. The size is 110.00 mm shaft, 130.00 mm housing bore and 13.00 mm height, with the Mx design. Gearboxes, pumps, electric motors and transmission equipment built around that shaft diameter are the usual homes for it. MR Industrial Accessories supplies it.

Reading the code is the first step. DBH names the line, 6738 is the item number, and the three figures describe the fit: d = 110.00 mm for the shaft, D = 130.00 mm for the housing bore, h = 13.00 mm for the height. Mx tells you the construction: one lip, backed by a spring, for rotating shafts that stay lubricated. The elastomer lip wipes the shaft while the spring holds it in contact, and the outside of the body presses into the housing so nothing creeps around the edge.

Where does a seal this size turn up? Speed reducers, centrifugal pumps, large electric motors, rollers, and belt or chain drives. In each case the job is the same: keep oil or grease where it belongs and shut out what does not belong. It also solves a common problem with older or imported machinery, where the original seal is hard to source and a matching size has to be found.

Installation rewards a little care. Confirm the shaft diameter falls inside the recommended tolerance and that its surface is free of scratches and wear. The housing should be clean, deburred and exactly 130.00 mm. Put lubricant on the lip before you press the seal in, and use a flat driver so the lip is not damaged. The 13.00 mm height has to line up with the housing depth. If the shaft shows a worn track, a seal with the lip in a different position or a repair sleeve is worth considering.

When you ask for a quote on 6738, include the shaft, housing and height measurements. A photo of the old seal or of the housing next to a caliper works just as well. We check those figures against the exact size in the same category. Avoid substituting by eye alone: the lip design and the elastomer compound both affect how long the seal lasts.
