This item is a radial shaft seal from the DBH brand, identified by part number 5858. Its dimensions are 31.75 mm shaft diameter (d), 42.87 mm housing bore (D) and 4.68 mm height (h). The Lz design corresponds to a seal with a sealing lip and spring, intended for rotating shafts. The lip, generally made of elastomer, presses against the shaft through the action of the spring, while the outer body ensures retention in the housing. It is a common replacement part in equipment with rotary motion.

Typical applications for this seal include gearboxes, pumps, electric motors, gear reducers and machinery bearings in general. Its main function is to prevent oil or grease leaks and protect bearings from the ingress of dust, water or particles. In industry, it is found in transmission equipment, conveyors, agitators and machine tools. Choosing the right seal depends on rotational speed, operating temperature and the type of lubricant.

To install this seal correctly, verify that the shaft and housing diameters match the indicated dimensions. The shaft must be free of burrs and have a suitable surface roughness so as not to damage the lip. Lubricate the lip with the same oil or grease used in the equipment before installation. Insert the seal perpendicular to the shaft, using a tube or press that bears on the outer diameter. Avoid striking the sealing lip. If the housing shows wear, consider using a seal with a larger outer diameter or a repair sleeve.
