The DBH 5987 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and stop the ingress of dust, water or particles. Its dimensions are 46.00 mm shaft diameter, 78.00 mm housing diameter and 10.00 mm height, with Mx-R design. It is used in gearboxes, pumps, electric motors and power transmission equipment that need a reliable barrier at the point where the shaft exits the housing.

This item is a DBH 5987 radial shaft seal, identified by the code 5987. Its dimensions are 46.00 mm shaft diameter (d), 78.00 mm housing diameter (D) and 10.00 mm height (h). The Mx-R design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The elastomeric lip presses on the shaft and the spring maintains contact pressure to compensate for wear and small concentricity variations.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. In all cases it performs the same function: prevent the leakage of oil or grease from inside the equipment and block the ingress of external contaminants that accelerate the wear of bearings and gears. It is also used on fan, mixer and conveyor shafts.

To install it, verify that the shaft has the indicated size, without burrs or marks, and that the housing is clean and the entry chamfer is in good condition. Lubricate the lip with the same grease or oil as the equipment before inserting it and do so with a flat pusher to avoid deforming the seal. When selecting a replacement, in addition to the three dimensions, take into account the type of lubricant, the working temperature and the shaft speed.
