The DBH 8422Pol radial shaft seal is a lip seal that is mounted in the housing and closes on the rotating shaft to retain lubricant and stop the ingress of dust, water or particles. Its Lx-Bidi design combines a main sealing lip with additional protection, which makes it suitable for equipment where the working environment is demanding. It is used in gearboxes, pumps, electric motors and transmissions that need reliable, low-maintenance sealing.

This DBH 8422Pol oil seal has a 32 mm shaft diameter, a 47 mm housing diameter and a 10 mm height. The Lx-Bidi design indicates a lip configuration with secondary protection, intended to contain lubricant in one direction and reinforce sealing against contaminants. The lip elastomer works on the shaft with controlled interference, while the outer body maintains the fit in the housing. It is a direct replacement part for equipment that already uses this size.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and transmission shafts. In such equipment, the seal prevents oil or grease leaks and protects the bearings from the ingress of dirt. It is also found in process equipment, conveyors and agricultural machinery where the shaft rotates continuously and environmental contamination is a factor to control.

For installation, check that the shaft has no burrs, wear or marks that could damage the lip, and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and do so with a flat-walled tool so as not to twist it. Seal selection depends on shaft speed, working temperature and the type of fluid; if those data are not clear, it is advisable to review the manufacturer's data sheet.
