The DBH 9912Vit 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 dimensions of 32 mm shaft, 42 mm housing and 8 mm height, and Lx-R H design, it is a common replacement part in gearboxes, pumps, electric motors and power transmission equipment operating with 32 mm shafts. MR Accesorios Industriales carries this brand and advises you so you order the correct seal.

This item is a radial shaft seal from the DBH line, identified by the code 9912Vit. Its dimensions are 32 mm shaft diameter, 42 mm housing diameter and 8.00 mm height. The Lx-R H design corresponds to a seal with a sealing lip and reinforced body, intended for rotating shafts with lubrication. The lip runs on the shaft and the outer circumference seats in the housing; that combination defines the fit and the type of application. Before replacing, verify that all three dimensions match the original seal.

Seals of this size are used in equipment where the 32 mm shaft needs oil or grease containment: gearboxes, reducers, centrifugal pumps, electric motors, compressors and machine tools. They also appear on transmission shafts of agricultural and industrial machinery. The function is twofold: prevent lubricant leaks to the outside and stop the entry of contaminants that wear bearings and bushings. That is why, when the seal loses elasticity or the lip becomes marked, it should be replaced before the damage reaches the bearings.

To select a seal correctly, the diameter alone is not enough: you must check the condition of the shaft, the surface roughness, the concentricity of the housing and the working temperature. A scratched or worn shaft means the lip will not seal even if the size is correct. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid striking it with tools that deform the body. If the housing has burrs, clean it before fitting. These precautions extend the service life of the seal.
