This item is a DBH 1128 radial shaft seal, identified by its designation 1128. Its dimensions are 65 mm shaft diameter (d), 77 mm housing diameter (D) and 7.50 mm height (h). The Mx design corresponds to a single-lip seal with spring, intended for rotating shafts. The DBH brand is an official brand that MR carries, so you can ask about alternatives within the same line.

Radial shaft seals such as the DBH 1128 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: to retain lubricant inside the assembly and to prevent the ingress of dust, water or particles that accelerate wear on bearings and gears. In environments with vibration or moderate temperature, a well-selected oil seal extends equipment service life and reduces unplanned downtime.

To install this oil seal, check that the shaft has the specified dimension and a surface free of burrs or marks. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, using a tube that bears on the outer diameter. Avoid striking the lip or the spring. If the housing shows wear, consider a nearby size or a seal with a sleeve. Correct alignment and prior cleaning are key to efficient sealing.
