The DBH 8902 is a radial shaft seal with an Lx design, sized for a 45.00 mm shaft, a 62.00 mm housing bore and a 7.00 mm width. It keeps lubricant in and contaminants out of rotating assemblies such as gearboxes, pumps, electric motors and power transmission equipment, protecting bearings and gears from premature wear.

The part number 8902 identifies this seal. Its Lx designation points to a single lip with a spring, a common choice for rotating shafts that run with lubrication. The elastomeric lip rides against the shaft while the metal case holds the seal in the housing. Because the lip is a wear component, hardening, cracking or visible marks on it are signs that oil retention is failing.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, spindles and transmission units. The job is always the same: keep oil where it belongs and block dust, water and particles from reaching the bearing or gear. In some machines it also acts as a secondary barrier where a shaft turns inside a fixed housing. In dirty or wet conditions, check the lip more often.

Before installation, confirm the shaft is clean and free of burrs or scoring in the contact zone, and that the housing bore is undamaged. Apply lubricant to the lip, then seat the seal square to the shaft without twisting it. A shaft with wear can sometimes be handled by a seal whose lip sits in a different position. Speed, temperature and the fluid being sealed determine the lip material and spring type.

If part number 8902 is not what you need, or you want a comparable size, send the shaft, housing and width dimensions along with a photo of the old seal. The team checks the catalog and proposes a compatible option. Providing more details leads to a more useful answer.
