The DBH 9922Vit seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and stop the entry of dust, water or particles. Its dimensions are 120 mm shaft, 140 mm housing and 13 mm height, with LMx-R AH design. It is used in gearboxes, pumps, electric motors and power transmission equipment where there is continuous rotation and the need for a reliable barrier.

This item is a DBH 9922Vit radial shaft seal, identified by its exact designation and by the dimensions shown on the product page: 120 mm shaft diameter, 140 mm housing diameter and 13.00 mm height. The LMx-R AH design corresponds to a lip seal with metal reinforcement and a specific geometry for rotary service. DBH is a brand that MR carries, so the code can be checked directly against the catalog to confirm the variant before quoting.

Typical applications for a seal of this size appear in equipment with medium-section shafts: gearboxes, centrifugal pumps, electric motors, rollers and belt or chain transmissions. In all those cases the seal performs two functions: keep the oil or grease inside the assembly and prevent the entry of contaminants that accelerate wear on bearings and gears. It is also used as a secondary closure in equipment where there is splashing or a dusty environment.

To install it properly, verify that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. The lip is lubricated before inserting it and is seated under pressure evenly, without striking the spring. If the shaft shows wear, it is advisable to evaluate a seal with an offset lip. The selection depends on speed, temperature and the type of fluid, data that is confirmed against the manufacturer's product page.
