The DBH 9971 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 28 mm shaft diameter, 47 mm housing diameter and a height of 6.50/9.50 mm, it corresponds to design A 308. It is used in gearboxes, pumps, electric motors and power transmission equipment where there is continuous rotation and the need for a reliable barrier.

This item is a radial shaft seal from the DBH line, identified by code 9971. Its dimensions are shaft (d) 28 mm, housing (D) 47 mm and height (h) 6.50/9.50 mm, with a design A 308. That double height indicates a profile with a lip section and a stepped body, intended for housings with a recess. The lip runs on the rotating shaft and the outer face seats on the housing diameter, creating the tight seal.

Typical applications for a seal of these dimensions are found in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. It is also found in machine tools and in systems where a bearing or a bushing needs to retain oil or grease and remain protected from the environment. As it is a wear component, it should be checked every time the equipment is disassembled to prevent leaks and contamination.

To select the correct seal, verify that the shaft diameter and the housing diameter match the values on the product page. The 6.50/9.50 mm height must fit into the cavity without deforming. Design A 308 defines the geometry of the lip and the body: do not replace it with another design without confirming compatibility. During installation, lubricate the lip, use an insertion tool and avoid striking it or reversing its orientation.
