The DBH 5310Sil radial shaft seal is a lip seal that mounts in the housing of a fixed component and seals against a rotating shaft. Its function is to retain lubricant inside the assembly and stop dust, water or particles from entering. It is used in gearboxes, pumps, electric motors and power transmission equipment, where axial space is limited and a reliable seal is required.

This item is identified by the designation 5310Sil and corresponds to a radial shaft seal from the DBH line. Its dimensions are 20 mm shaft diameter, 42 mm housing diameter and 7.00 mm height. The indicated design is Lz, a single-lip profile with a spring that runs on rotating shafts. DBH is an official brand that MR carries, so the part number can be checked directly against the catalog.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. It is also found on fan, mixer and conveyor shafts, where the seal prevents oil or grease leaks and protects the bearings from contaminant ingress. It is a wear part that should be replaced when a visible leak appears or when the lip shows stiffness or wear.

To select and install a radial shaft seal, verify that the shaft diameter, housing diameter and height match the dimensions of the original part. The shaft must be clean, free of burrs and deep marks, and the housing must have the lead-in chamfer in good condition. Before installing it, lubricate the lip with the same oil or grease used in the equipment and avoid striking it during installation. Poor alignment or a damaged lip shortens the service life of the seal.
