The DBH 5516 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Due to its dimensions of 38.10 mm shaft, 50.52 mm housing and 6.35 mm height, and its Mx design, it is used in gearboxes, pumps, electric motors and power transmission equipment that need reliable, low-maintenance sealing.

This item is a DBH 5516 radial shaft seal, identified by its designation 5516. Its attributes are: shaft diameter 38.1 mm, housing diameter 50.52 mm, height 6.35 mm and Mx design. That combination of dimensions corresponds to a seal with a compact cross-section, intended for housings with little axial space. The Mx design defines the geometry of the lip and the outer body, and it is advisable to verify that it is suitable for the type of shaft and lubricant in your equipment before installing it.

Typical applications for a seal of these dimensions appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all these cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is also used as a secondary seal on shafts that rotate at moderate speeds and with low differential pressure.

To select and install a radial shaft seal, take into account the condition of the shaft: the track where the lip rests must be polished, without grooves or burrs, because any mark causes a leak. Verify that the housing diameter and height match the 50.52 mm and 6.35 mm of this DBH 5516, and that the Mx design is compatible with the direction of rotation and the type of lubricant. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it from the side.

If you need an equivalent or a nearby size, the most practical thing is to send us the full code, the designation 5516 or the three dimensions of the old seal: shaft, housing and height. With that data we can look for an alternative within the DBH line or other brands we carry. If the original seal has no legible identification, measure the shaft and housing with a caliper, and tell us the type of equipment and lubricant to guide the selection.
