This item is a radial shaft seal from the DBH line, identified by code 5631. The Mz design indicates a specific construction configuration within the radial shaft seal category. Its dimensions are 28.00 mm shaft diameter, 43.00 mm housing diameter and 10.00 mm height. It is a lip seal that works on a rotating shaft, with the lip resting on the running surface and the body fixed in the housing. It is not an axial seal or a static seal: it is intended for continuous rotary motion.

Typical applications for a seal such as the 5631 appear in gearboxes, pumps, electric motors, transmission shafts and equipment with bearings lubricated with oil or grease. It is also used in agricultural machinery, conveyors and process equipment where the lubricant must be protected and contamination kept out. In all cases, the seal works alongside a bearing or a bushing, and its service life depends on the cleanliness of the environment, the shaft speed and the operating temperature.

To fit this seal, check that the shaft has the 28 mm dimension and the housing the indicated 43 mm. The 10 mm height defines the space required in the housing. Check that there are no burrs or scratches on the shaft, because they damage the lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it unevenly. If the equipment operates with high vibration or temperature, ask whether a different compound is advisable. The final selection is always confirmed against the manufacturer's data sheet.
