The DBH 9540 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and stop the ingress of dust, water or particles. Its Mx design and its dimensions of 38 mm shaft, 51 mm housing bore and 5.70 mm height place it in applications with limited space, such as gearboxes, pumps, electric motors and transmission equipment that need a reliable, low-maintenance seal.

The DBH 9540 is a radial lip seal with the following dimensions: 38 mm shaft diameter, 51 mm housing bore and 5.70 mm height. The Mx design corresponds to the standard single-lip construction with a spring, intended for rotating shafts with permanent lubrication. The elastomeric lip runs on the shaft and the outer body is an interference fit in the housing, so the seal stays fixed and the sliding surface is the shaft. It is a wear part: over time the lip hardens or becomes marked and starts to leak.

This type of seal is used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment where there is a shaft rotating inside a housing with oil or grease. It also appears in applications exposed to dust or splashes, where in addition to retaining lubricant, contaminant ingress must be prevented. In those cases, it is advisable to verify that the lip material is compatible with the fluid and the operating temperature before specifying it.

To select and install a seal, the three dimensions must be respected: shaft diameter, housing bore and height. The shaft must be within tolerance and have a suitable surface roughness; if it has burrs, grooves or wear, the new lip will be damaged on entry. It is advisable to lubricate the lip before installation, seat it perpendicular and use an installation tube or bushing that pushes on the outer body, never on the lip. If the housing has a radius or a chamfer, verify that the seal seats fully.
