The DBH 6342 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 40.48 mm shaft, 63.40 mm housing and 7.31 mm height, together with the Ls design, make it suitable for equipment where axial space is limited and a reliable seal is required. MR Accesorios Industriales supplies this official brand and advises you so you choose the right oil seal for your application.

This item is a DBH 6342 radial shaft seal, identified by its designation 6342. Its main attributes are: shaft diameter (d) of 40.48 mm, housing diameter (D) of 63.40 mm and height (h) of 7.31 mm. The Ls design corresponds to a single lip configuration with spring, intended for single-direction rotation applications. These dimensions and construction features are what define its mounting and its sealing function.

Radial shaft seals such as the DBH 6342 are used in gearboxes, pumps, electric motors, transmission shafts and industrial equipment in general. Their 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. They are critical components in maintenance, since a seal failure can lead to lubricant loss and premature damage to other elements.

To correctly select an oil seal you must verify the shaft and housing dimensions, the type of lubricant, the rotation speed and the working temperature. The Ls design is suitable for shafts with good surface finish and controlled hardness. During mounting, it is essential to clean the surfaces, lubricate the lip and use a tool that does not damage the seal. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
