The DBH 8459 is a single-lip radial oil seal built for rotating shafts measuring 32 mm in diameter. It keeps lubricant contained within the housing while blocking dust, water and particles that would otherwise speed up wear on bearings and bushings. The seal presses into a 48 mm bore and measures 8 mm in height. You will find it in gearboxes, pumps, electric motors and other power transmission equipment that runs under tough conditions.

This seal follows the Lx design and its key dimensions are: shaft 32 mm, housing 48 mm, height 8.00 mm. The sealing lip is reinforced to handle constant contact with the shaft and to stay tight even when minor eccentricity is present. A metal outer case holds the seal firmly in the housing, and the inner elastomer stands up to the industrial oils and greases commonly used in plant equipment. It is a compact, dependable choice for installations where space is limited.

You will typically find the DBH 8459 in gearboxes, centrifugal pumps, electric motors, compressors, conveyor rollers and belt or chain drive systems. In each case, the seal stops lubricant from escaping and keeps contaminants out, which helps bearings last longer and cuts unplanned downtime. It also sees use in machine tools, agricultural machinery and hydraulic systems that need effective sealing on rotating shafts.

When installing, verify that the shaft has the correct hardness and surface finish, free of burrs or marks that could harm the lip. Apply the same oil or grease used in the equipment to lubricate the lip before fitting, and use an installation tool that pushes on the outer diameter, never on the lip itself. Selection should account for rotation speed, operating temperature and the fluid being retained. If anything is unclear, share your application details with us.
