The DBH 5165 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 28 mm shaft diameter, 45 mm housing diameter and 7.50 mm height, and Lx design, it is a commonly used size in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales carries this brand and will quote it for you on WhatsApp.

The DBH 5165 is a single-lip radial shaft seal, identified by its designation 5165. Its dimensions are 28.00 mm shaft diameter (d), 45.00 mm housing diameter (D) and 7.50 mm height (h). The Lx design corresponds to a seal with a sealing lip and an outer metal body, designed to be press-fitted into a cylindrical housing. The Lx nomenclature defines the geometry of the lip and the reinforcement, not the elastomer material, which is confirmed against the manufacturer's data sheet at the time of quoting.

This type of seal is used where a shaft rotates inside a housing and oil or grease must be contained: centrifugal pumps, electric motors, gearboxes, conveyor rollers, mixers and belt- or chain-driven transmission equipment. It also appears in applications where the environment has dust or moisture and the bearing or bushing behind the seal needs protection. It is a wear part: it is replaced when lubricant leakage or contaminant ingress appears.

To select a seal, three things must be verified: that the shaft diameter is within the recommended tolerance, that the housing has the correct diameter and depth, and that the lip runs on a surface free of grooves or wear. The Lx design is mounted with the lip facing the fluid side to be retained. If the shaft has a groove or a shoulder, the axial position of the lip should be checked so that it does not fall on the damaged area. Peripheral speed and operating temperature are data confirmed against the manufacturer's data sheet.

If you need a nearby size or an equivalent, the most practical thing is to send the code 5165 or the dimensions 28 x 45 x 7.50 by WhatsApp. With that data, an alternative from the same series or from another brand with the same shaft and housing diameter can be found. If the housing accepts a different height, a seal with a greater or lesser height can also be evaluated. The more complete the equipment information, the faster the response.
