The DBH 9516Vit radial shaft seal is a lip seal that closes off the passage of oil, grease or water between a rotating shaft and its housing. With a 20.00 mm shaft diameter, 40.00 mm housing diameter and 8.00 mm height, and an Lr-Bidi design, it is used to retain lubricant and block the entry of dust and contaminants in gearboxes, pumps and motors. It is a wear part: when the lip hardens or the shaft gets marked, it starts to leak.

This seal is identified by its designation 9516Vit and by its dimensions: 20.00 mm shaft diameter (d), 40.00 mm housing diameter (D) and 8.00 mm height (h). The Lr-Bidi design indicates a lip configuration that works in both directions, with a profile designed to be mounted in housings where the seal must contain the lubricant and at the same time stop dirt from entering from the outside.

Typical applications for a seal of these dimensions appear in equipment with small-diameter transmission shafts: gearboxes, centrifugal pumps, electric motors, rollers and conveying mechanisms. It is also found in machine tools and in process equipment where an oil bath must be separated from an environment with dust, chips or wash water. In all these cases it performs the same function: keeping the lubricant in and the contaminant out.

To select it correctly, check that the shaft and housing diameters match the dimensions of the part, and that the 8.00 mm height fits into the cavity without deforming the lip. Check the condition of the shaft: if it has a groove, burr or wear, the new lip will not seal even if the dimension is correct. During installation, lubricate the lip, seat the seal perpendicular to the shaft and push evenly, without hitting the lip or the spring. If the housing has a shoulder or radius, take it into account before forcing the part.

If you need an equivalent or a nearby size, send us the part number 9516Vit along with the shaft and housing dimensions, the type of lubricant and the working temperature. With that data we can look for an alternative from the same brand or from another brand that MR carries, and confirm against the manufacturer's data sheet whether the Lr-Bidi design is the right one for your equipment. If the seal is mounted in an assembly, it is also worth checking the condition of the nearby bearing or bushing.
