This item is a radial shaft seal from the DBH brand, identified by part number 6646. Its dimensions are 72 mm shaft diameter (d), 127 mm housing bore (D) and 11.90 mm height (h). The Mx design corresponds to a configuration with a sealing lip and metal case, suitable for rotating shafts. The lip, generally made of elastomer, runs on the shaft and prevents oil or grease leaks, while the outer diameter fits into the housing to ensure sealing.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, electric motors, compressors and transmission equipment. In all cases, its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. It is commonly found in agricultural machinery, material handling equipment and production lines where sealing reliability is critical to avoid unplanned downtime.

To install a radial shaft seal correctly, check that the shaft has no burrs or excessive wear in the contact area. Lubricate the lip before installation and use a press or suitable tool to insert it perpendicular to the shaft, without striking it directly. Selection must consider peripheral speed, operating temperature and the type of fluid to be retained. If the original seal shows premature leaks, check the shaft roughness and the concentricity of the housing.
