The DBH 9105 radial shaft seal is a lip seal designed to close off lubricant and prevent contaminants from entering rotating equipment.

MR Accesorios Industriales supplies this brand and advises you so you choose the correct oil seal for your equipment.

This item is a DBH 9105 radial shaft seal, identified by its numeric designation. Its standard dimensions are 20.00 mm shaft diameter (d), 45.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design corresponds to a specific construction configuration within the DBH line, which combines a sealing lip and a metal reinforcement structure. It is a direct replacement part for 20 mm shafts that rotate inside a 45 mm housing, with a width of 7 mm.

Radial shaft seals such as the DBH 9105 are used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. Their main function is to retain oil or grease inside the assembly and block dust, water or particles that could damage bearings and gears. They are common in the food, cement, mining and process industries, where cleanliness and sealing reliability are critical to avoid unplanned downtime.

To install this oil seal correctly, verify that the shaft has no burrs or excessive wear in the contact area, 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 install the seal perpendicular to the shaft, applying uniform pressure on the outer circumference. If the shaft has a groove or wear, consider using a seal with an auxiliary lip or a wear sleeve. Lip material selection also depends on temperature and the fluid to be retained.
