The DBH 5233Sil oil seal is a radial shaft seal with a 75 mm shaft diameter, 100 mm housing diameter and 12 mm height, in Lz design. It is used to retain lubricant and exclude contaminants on rotating shafts, in gearboxes, pumps, electric motors and power transmission equipment. Its flexible lip runs on the shaft and maintains sealing under continuous rotation. MR Accesorios Industriales carries this brand as part of its seals and oil seals line.

This item is a DBH radial shaft seal, identified by the designation 5233Sil. Its dimensions are 75.00 mm shaft diameter (d), 100.00 mm housing diameter (D) and 12.00 mm height (h). The Lz design corresponds to a configuration with a sealing lip and spring, suitable for rotating shafts with lubrication. The 100 mm outer diameter is press-fitted into the housing, while the 75 mm lip rests on the shaft. The 12 mm height defines the axial space required in the cavity.

Typical applications for an oil seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all cases, the function is twofold: to prevent oil or grease from leaking out and to block the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used in machine tools and continuous process equipment.

To correctly install a radial shaft seal, check 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 or grease used in the equipment before inserting it into the housing. Installation must be perpendicular to the shaft and with even pressure on the outer ring, never on the lip. If the shaft shows wear, consider a repair sleeve or an alternative size. Selection depends on speed, temperature and type of lubricant.
