The DBH 8429Vit radial shaft seal is a lip seal for rotating shafts. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles. With dimensions of 90 mm shaft diameter, 110 mm housing diameter and 11 mm height, and an Lx-R design, it is press-fitted into the housing and runs on the shaft. It is a wear part: it should be checked at every maintenance interval to prevent leakage and contamination.

This DBH 8429Vit seal has a shaft diameter of 90 mm, a housing diameter of 110 mm and a height of 11.00 mm. The Lx-R design indicates a configuration with a sealing lip and spring, suitable for rotating shafts. The DBH brand is an official brand that MR carries, so the replacement part is identified by its exact code. Before ordering, verify that the three dimensions match your equipment's housing and shaft, since even a minimal difference prevents correct installation.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, rollers and transmission equipment. In general, they protect bearings and gears from the entry of contaminants and from the loss of oil or grease. In applications with a rotating shaft and the presence of dust or moisture, the lip must maintain uniform contact. If the equipment operates with vibration or misalignment, it is advisable to check the condition of the shaft and housing before replacing the seal.

To select the correct seal, take into account the shaft diameter, the housing diameter and the height. The Lx-R design defines the type of lip and its orientation. During installation, lubricate the lip with the same lubricant used in the equipment, insert it perpendicular to the shaft and use a tube or press that bears on the outer diameter, never on the lip. Verify that the shaft has no burrs or excessive wear in the contact area, because that accelerates seal failure.
