It is used in gearboxes, pumps, electric motors and transmission equipment to protect bearings and gears. MR Accesorios Industriales sells this brand and advises you on choosing the correct seal for your application.

This item is a DBH 9785 radial shaft seal. Its attributes indicate: shaft diameter 25 mm, housing diameter 40 mm, height 9.00 mm and Lx design. The Lx design corresponds to a sealing lip with spring, intended for rotating shafts with lubrication. The seal is press-fitted into the housing and its flexible lip contacts the shaft to prevent oil or grease leaks and the ingress of dust, water or particles. It is a wear part that should be replaced when lubricant loss or bearing noise appears.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It is also used in machine tools, conveyors and agricultural or road equipment where there are rotating shafts that need lubricant containment. In all cases, the seal protects the bearings and extends the service life of the assembly, provided the material and lip type are suitable for the temperature and working fluid.

For correct installation, check that the shaft has the indicated dimension, free of burrs and marks, and that the housing is clean and undamaged. Lubricate the lip with the same oil or grease used in the application before inserting it. Use a tube or press that bears on the outer diameter, never on the lip. If the shaft shows wear, consider a seal with an auxiliary lip. Selection depends on speed, temperature and lubricant type; ask us if you have any doubts.
