The DBH 9630/85 radial shaft seal is a lip seal designed to prevent oil or grease leaks and the ingress of contaminants on rotating shafts. Its measurements of 50.90 mm shaft diameter, 56.80 mm housing diameter and 5.90/7.20 mm height make it suitable for equipment with limited axial space. It is used in gearboxes, pumps, electric motors and general machinery, where sealing reliability is key to avoiding unplanned downtime.

This DBH 9630/85 seal has a 50.90 mm shaft diameter, a 56.80 mm housing diameter and a 5.90/7.20 mm height. The A 266 design corresponds to a single-lip configuration with spring, intended to retain lubricant and exclude dust in moderate-rotation applications. DBH is a brand that MR carries, so you can ask us about this size and its equivalents.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, spindles and transmission equipment. In all cases, the seal works on a rotating shaft and must withstand lubricant pressure and the ambient conditions of the environment. It is commonly found in equipment where radial space is limited and efficient, low-friction sealing is required.

To install this seal correctly, verify that the shaft has the proper hardness and roughness, and that the housing is clean and free of burrs. The 5.90/7.20 mm height allows some flexibility in axial fit, but it is important to respect the manufacturer's tolerances. When selecting a replacement, consider rotation speed, operating temperature and the type of lubricant. If the original seal has a different design, consult us to evaluate a compatible alternative.

If you need a seal with nearby dimensions or an equivalent from another brand, the most practical approach is to send us the full code (9630/85) or the shaft, housing and height measurements. With that data we can search our catalog for the option that best fits. We can also advise you on the lip design and elastomer material according to the fluid to be retained.
