The DBH 6734Pol is a radial shaft seal sized 28 x 47 x 8 mm and built to the Mz-R-H configuration, which pairs a sealing lip with a metal reinforcement. It keeps oil, grease and outside contamination where they belong in rotating assemblies, and it is a common find in gearboxes, pumps, motors and rollers. MR Industrial Accessories supplies this brand and can help you confirm the size before you order.

Reading the number is straightforward. The 6734Pol designation is the manufacturer's reference, and the three figures that follow describe the fit: shaft 28 mm, housing 47 mm, height 8.00 mm. Because the Mz-R-H build uses a lip plus reinforcement, it suits housings that see moderate pressure while still holding lubricant in and dust out. Measure the shaft and bore, and check surface finish, before you press anything into place.

You will run into this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. In each case the job is the same: stop lubricant from escaping and stop dust or water from reaching the bearing. Agricultural and road machinery also use it, where vibration and shifting temperatures are part of daily operation. If the housing runs under internal pressure, verify that the Mz-R-H design fits that condition.

Selection starts with the three dimensions, but the shaft condition matters just as much. The lip needs a ground surface with no splines under it, and a worn shaft may call for a wear sleeve or a seal with an auxiliary lip. Lubricate the lip with the same oil or grease the equipment uses, and seat it with a support tube so the lip is not rolled or cut. Keep shaft and housing runout inside the limits set for this seal type.
