The DBH 8981 radial shaft seal is a single-lip seal that mounts in the housing and closes on the rotating shaft to retain lubricant and stop the ingress of dust, water or particles. Its dimensions of 75 mm shaft, 115 mm housing and 12 mm height place it in medium-sized transmission equipment and pumps. It is a wear part: when oil loss appears or the lip looks hardened, it should be replaced.

The DBH 8981 is a seal with Lx design, with a sealing lip and metal body for press fitting into the housing. It works on a shaft of 75 mm diameter, in a housing of 115 mm and with 12.00 mm total height. That combination of dimensions corresponds to a medium section, common in gearboxes, pumps and power transmission equipment where radial space is limited and a reliable closure is needed.

It is used in gearboxes, centrifugal pumps, electric motors, mixers and process equipment where there is a shaft rotating inside a housing with lubricant. It also appears in agricultural machinery and conveyor lines. In all these cases it performs the same function: keeping oil or grease inside and preventing contaminants from entering that accelerate wear on bearings and gears.

To select it, verify that the shaft diameter, housing and height match those of the original seal. The Lx design defines the type of lip and its orientation; if the equipment operates with a lot of dirt or at high speeds, it is advisable to evaluate a variant with a dust lip or a different material. When installing, lubricate the lip, make sure the shaft has no burrs or marks and tap the seal evenly until it seats at the bottom of the housing.
