The DBH 9091 radial shaft seal is a lip seal designed for rotating shafts. With dimensions of 20 mm shaft diameter, 40 mm housing bore and 7 mm height, it provides reliable sealing against oil or grease leaks and keeps contaminants out. Its Lx design corresponds to a single sealing lip with spring, suitable for general industrial applications where an effective and long-lasting barrier is required.

This item is a DBH radial shaft seal, identified by part number 9091. Its standard dimensions are 20.00 mm shaft diameter (d), 40.00 mm housing bore diameter (D) and 7.00 mm height (h). The Lx design indicates a single lip configuration with spring, which ensures uniform contact on the shaft. Made with elastomers resistant to oils and greases, it is suitable for moderate temperatures and peripheral speeds typical of industrial equipment.

Typical applications include centrifugal pumps, electric motors, gearboxes, compressors and power transmission equipment. In all cases, the seal protects bearings and gears from dust, water or particles, and retains the lubricant inside the assembly. It is a critical part in the preventive maintenance of rotating machinery, where a failure can cause unplanned downtime and major damage.

For correct installation, check that the shaft has adequate hardness and surface finish, with no burrs or marks. Lubricate the lip before inserting it and make sure the housing is clean and free of deformation. Selection must consider rotation speed, operating temperature and the type of fluid to be retained. If the original seal shows wear, replace it with one of the same dimensions and design to maintain sealing performance.
