The DBH 9540 radial shaft seal is a lip seal mounted in the housing that seals against the rotating shaft to retain lubricant and stop the entry 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 power 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 diameter and 5.70 mm height. The Mx design corresponds to the standard single-lip construction with spring, intended for rotating shafts with permanent lubrication. The elastomeric lip works on the shaft and the outer body fits by interference in the housing, so that the seal remains 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 radial shaft 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 the lubricant the entry of contaminants must be prevented. In those cases it is advisable to verify that the lip material is compatible with the fluid and the working temperature before defining it.

To select and mount a radial shaft seal, the three dimensions must be respected: shaft diameter, housing bore diameter and height. The shaft must be within tolerance and with adequate roughness; if it has burrs, grooves or wear, the new lip is damaged on entry. It is advisable to lubricate the lip before mounting it, 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, check that the seal seats fully.
