The DBH 8307 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 —46 mm shaft, 63 mm housing and 9 mm height— it is used in gearboxes, pumps, electric motors and power transmission equipment. It is a wear part: when the lip hardens or marks the shaft, it should be replaced before the bearing fails.

This item is a seal from the DBH line, identified with part number 8307. Its dimensions are 46.00 mm shaft diameter, 63.00 mm housing diameter and 9.00 mm height. The Mx design corresponds to the construction with sealing lip and metal body, designed for press-fit mounting in the housing. Before ordering, verify that these three dimensions match the housing and shaft of your equipment: they determine whether the seal seats and seals correctly.

Seals of this size are found in gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. They also appear in agricultural machinery, conveyors and process equipment where a rotating shaft exits a lubricated crankcase. In all these cases the function is the same: keep oil or grease inside and contaminants outside, protecting bearings and gears.

To select a seal correctly, in addition to the dimensions, take into account the shaft speed, working temperature and type of lubricant. A poorly lubricated lip or a shaft with wear or deep scratches shortens the life of the seal. During assembly, the seal is inserted perpendicular to the shaft, without hitting the lip, and it is advisable to lubricate the edge before sliding it on. If the shaft shows a marked track, consider a wear sleeve or a seal size with the lip in another position.

If you need an equivalent, the most practical thing is to send us part number 8307 and, if possible, a photo of the old seal and the measurements taken with a caliper. With that data we review alternatives within the DBH line or other brands we carry. If the housing or shaft has another dimension, we can also look for an available size so that assembly is not forced.
