A radial shaft seal such as the DBH 9902Pol keeps lubricant inside a housing where a rotating shaft passes through, and keeps dust, water and particles out. The outer body is press-fitted into the bore while the lip rides on the shaft with light interference. Because it is a wear part, a hardened lip or a marked shaft surface will reduce its sealing ability over time.

The code 9902Pol belongs to the DBH line. Its three dimensions are: shaft 47.6 mm, housing 63.7 mm, height 10.00 mm, plus design A 340. In practice, the lip runs against a 47.6 mm shaft, the outer body seats in a 63.7 mm cavity, and the 10.00 mm height is the room the seal takes up in the bore once installed.

Typical installation points include gearboxes, pumps, electric motors, rollers and transmission equipment with a shaft turning inside a lubricated housing. The same seal also suits locations where dust or water is present and the barrier has to work in both directions. Maintenance teams in agricultural machinery, production lines and plant equipment handle this size regularly.

Selection comes down to matching the old part. Confirm the shaft diameter and the bore diameter, and make sure the height fits the cavity without being squeezed. Inspect the shaft as well: a groove or wear track under the lip means a new seal will not hold. When fitting, coat the lip with lubricant, press the seal in square and drive it on the outer edge, never on the lip.

To quote 9902Pol, send the dimensions of the seal being replaced: shaft diameter, housing diameter and height. With those three values the team can locate the equivalent in the same line or in another brand carried. If the shaft shows wear, options with a different height or an auxiliary lip can also be reviewed.
