This item is a DBH radial shaft seal, identified by the designation 6728. Its dimensions are 13.40 mm shaft diameter (d), 25.30 mm housing diameter (D) and 9.52 mm height (h). The Lx design corresponds to a single-lip configuration with spring, intended to retain oil or grease on rotating shafts. DBH is a brand that MR carries, so you can ask us about its applications.

Radial shaft seals such as the DBH 6728 are used in gearboxes, pumps, electric motors, compressors and belt or chain drives. Their function is twofold: keep the lubricant inside the assembly and block dust, water or particles that could wear down bearings and gears. In equipment with small-diameter shafts, this type of seal is key to extending component service life and reducing maintenance downtime.

To install a radial shaft seal, check that the shaft and housing diameters match the dimensions indicated. The shaft surface must be clean, free of burrs and deep marks, and it is advisable to lubricate the lip before inserting it. The Lx design tolerates some misalignment, but it is important that the seal sits perpendicular to the shaft. If the shaft shows wear, consider a neighboring size or a seal with an auxiliary lip.
