The DBH 5545 seal is a radial shaft seal with an Lz design that is fitted between a rotating shaft and its housing to retain lubricant and block the entry of dust, water or particles. Its dimensions —88 mm shaft, 120.62 mm housing and 13.00 mm height— make it a replacement part for equipment where axial space is limited and a reliable closure is needed. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

This item is a DBH radial shaft seal identified by the designation 5545. Its dimensional attributes are: shaft diameter 88 mm, housing diameter 120.62 mm and height 13.00 mm. The Lz design corresponds to a configuration with a sealing lip and metal reinforcement, intended for rotating shafts with permanent lubrication. The lip elastomer runs on the shaft track, while the outer diameter fits into the housing to prevent leaks. It is a wear part: when the lip hardens or becomes marked, it starts to lose oil.

Seals of this size are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. They also appear in old or imported machines where the housing has inch dimensions converted to millimeters, as in this case of 120.62 mm. In food, paper or chemical plants, the seal serves a dual purpose: it retains the lubricant and prevents the product or wash water from entering the bearing. If the equipment works with high vibration or temperature, it is worth checking the condition of the shaft before replacing.

To install a radial shaft seal, the shaft must be clean, with no burrs or splines that could cut the lip. Lubricate the lip with the same grease or oil used in the equipment and check that the housing has no impacts. The height of 13.00 mm must match the housing depth; if the seal sits out of plane, it seals poorly. When choosing a replacement, respect the shaft diameter and the housing diameter; the Lz design may vary between manufacturers, but the dimensions are the starting point. If the shaft is worn, consider a repair sleeve.
