The DBH 8902 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 45.00 mm shaft, 62.00 mm housing and 7.00 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment, where sealing protects bearings and gears.

This item is a DBH 8902 radial shaft seal, identified by its part number 8902. It works on a 45 mm diameter shaft, with a 62 mm housing and a total height of 7.00 mm. The Lx design corresponds to a single-lipped seal with spring, intended for rotating shafts with lubrication. The elastomeric lip bears on the shaft and the metal case fits into the housing to maintain sealing during rotation. It is a wear part: when the lip hardens or becomes marked, it starts to lose oil.

Typical applications for a seal of these dimensions appear in gearboxes, centrifugal pumps, electric motors, spindles and transmission equipment. In all cases it performs the same function: preventing lubricant from escaping and contaminants from entering the bearing or gear. It is also used as a secondary closure in equipment where a shaft rotates inside a fixed housing. If the equipment operates with a lot of dirt or water, it is advisable to check the condition of the lip more frequently.

To install it, verify that the shaft is clean, without burrs or marks in the contact area, and that the housing has no dents. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without twisting it. If the shaft is worn, a seal with the lip in another position can solve it. The selection depends on speed, temperature and fluid; with that data the lip material and spring type are chosen.
