The DBH 9633 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 29.50 mm shaft diameter, 42.00 mm housing bore and 3.30 mm height, this component is press-fitted into the housing and runs against the rotating shaft. It is a key part in gearboxes, pumps and electric motors, where it prevents leaks and extends bearing life. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal.

The DBH 9633 is a seal with an A 264 design, with the stated dimensions: 29.50 mm shaft diameter, 42.00 mm housing bore and 3.30 mm height. This type of seal combines an elastomeric lip with a metal case that gives it rigidity and allows press fitting. The A 264 designation corresponds to a specific geometry that defines the lip profile and the spring, aimed at low-friction and high-speed applications. It is important to respect these dimensions to ensure a correct fit and avoid premature leaks.

Radial shaft seals such as the DBH 9633 are used in a wide variety of industrial equipment: gearboxes, centrifugal pumps, electric motors, compressors and spindles. Their main function is to keep lubricant inside the assembly and prevent the ingress of dust, water or particles that accelerate wear on bearings and gears. In environments with oil or grease, a well-selected seal reduces maintenance downtime and protects internal components.

To correctly select a seal, in addition to the dimensions, you must consider rotation speed, operating temperature and the type of fluid to be retained. The A 264 design is often used in applications where the shaft rotates at moderate or high speeds and low heat generation is sought. During assembly, it is essential to lubricate the lip, verify that the shaft has no burrs or grooves, and use an installation tool that prevents damaging the seal. Poor installation is the most common cause of early failures.
