The DBH 9002 seal is a single-lip radial shaft seal designed for rotating shafts of 125 mm diameter and housings of 150 mm, with a height of 12 mm. Its function is to retain the lubricant inside the assembly and block the entry of dust, water or particles that accelerate the wear of bearings and bushings. It is press-fitted into the housing and works on the shaft with the lip in contact, so correct selection and installation are key to preventing leaks and extending the service life of the equipment.

This item is a radial shaft seal from the DBH line, identified by the code 9002. Its dimensions are 125 mm shaft, 150 mm housing and 12.00 mm height, with an Lx design. The Lx design corresponds to a seal with a sealing lip and spring, suitable for rotating shafts with lubrication. The 9002 nomenclature follows the DBH numerical designation system: the first two digits indicate the housing diameter and the last two the shaft diameter, always in millimeters. The 12 mm height defines the axial space it occupies in the cavity.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, industrial fans and power transmission equipment. In all cases, the seal protects the bearings or bushings from the entry of contaminants and prevents the loss of oil or grease. It is commonly found in equipment where the shaft rotates at medium speeds and the working temperature does not exceed the limits of the standard elastomer. It is also used in agricultural machinery and in continuous process lines.

To correctly select a seal, verify that the shaft and housing dimensions match those of the actual housing and shaft, and that the height is compatible with the depth of the cavity. The Lx design requires an entry chamfer in the housing so as not to damage the lip during installation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows wear or grooves, consider a wear sleeve or an alternative lip position.

If you need a seal equivalent to the 9002 or a nearby size, the most practical approach is to send us the complete code, the shaft, housing and height dimensions, and a photo of the original seal. With that data we can look for the alternative in the DBH line or in other brands we carry. If the seal is mounted in equipment with bearings, we can also verify compatibility with the assembly and suggest the appropriate replacement. You do not need to have the data sheet on hand: the code is enough to start the inquiry.
