The DBH 8912 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and keep out dust, water, and particles. Its Lx design and dimensions of 50 mm shaft, 68 mm bore, and 10 mm width make it suitable for power transmission equipment and continuous-duty machinery, where proper sealing determines bearing and assembly life.

This item is a DBH radial shaft seal identified as 8912. It works on a 50 mm diameter shaft, fits into a 68 mm bore, and is 10 mm wide. The indicated design is Lx, which corresponds to a single-lip seal with a metal case and sealing lip. DBH is an official brand sold by MR, so the 8912 code can be checked against the catalog to confirm geometry before requesting a quote.

Seals of this size are used in gearboxes, pumps, electric motors, rollers, and power transmission equipment. Their function is twofold: retain oil or grease inside the assembly and prevent contaminants from entering. In applications with a rotating shaft and lubricant bath, a well-chosen seal reduces bearing wear and extends maintenance intervals.

To select it, first check the shaft diameter and bore diameter with calipers, because a 50 x 68 x 10 seal does not allow substitutions with nearby sizes without machining. Also check the shaft surface condition: a scored or burred track ruins the new lip within hours. When installing, lubricate the lip, seat the seal perpendicular, and tap on the outer face, never on the lip. If the equipment runs at high temperature or speed, contact us and we will evaluate the appropriate compound.

If code 8912 is not on your list or you need a nearby size, send us the shaft, bore, and width dimensions along with a photo of the old seal. With that data we can find the equivalent in DBH or another brand we carry, always respecting the original geometry. We can also advise you if the seal is mounted in a housing or cover that should be replaced.
