Its Lz design provides effective retention in applications with moderate speeds and demanding operating conditions.

This item is a DBH brand radial shaft seal, identified by part number 5112. Its standard dimensions are: shaft diameter (d) of 25.40 mm, housing bore diameter (D) of 44.50 mm and height (h) of 5.00 mm. The Lz design corresponds to a spring-loaded sealing lip, intended for rotating shafts where low friction and good wear resistance are required. The lip elastomer and the metal body are bonded together to withstand moderate pressure and operating temperatures typical of industry.

The most common applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases, its function is to retain oil or grease inside the assembly and block the entry of dust, water or particles. It is a critical part in machinery maintenance, since its failure can cause lubricant loss and premature damage to bearings and gears.

To correctly install a seal such as the 5112, verify that the shaft has the proper hardness and surface finish, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil used in the equipment before installation and make sure the housing is clean and free of deformation. Selection must consider the peripheral shaft speed, the operating temperature and the chemical compatibility of the elastomer with the fluid to be retained.
