The DBH 9630/85 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its dimensions are 50.90 mm for the shaft, 56.80 mm for the housing bore, and a height of 5.90/7.20 mm. This profile fits assemblies where axial room is tight, such as gearboxes, pumps, electric motors, and general machinery. A reliable seal here helps avoid unexpected stoppages.

This seal follows the A 266 design, which means a single lip with a spring. That configuration is intended to hold grease or oil and block dust under moderate rotation. The code 9630/85 identifies the size. DBH is a brand we supply, so you can ask about this reference and possible equivalents.

You will find seals like this on rotating shafts in gearboxes, centrifugal pumps, electric motors, spindles, and transmission equipment. They must handle lubricant pressure and the surrounding environment. They are common where radial space is limited and low-friction sealing is needed.

Proper installation starts with checking shaft hardness and surface roughness, and making sure the housing is clean and free of burrs. The 5.90/7.20 mm height gives some room in axial positioning, but stay within the manufacturer's tolerances. When choosing a replacement, factor in rotation speed, operating temperature, and the lubricant type. If your original seal has a different design, contact us to review a compatible option.

If you need this seal or an equivalent from another brand, the quickest way is to send the full code (9630/85) or the shaft, housing, and height measurements. With that information we can check our catalog for the best match. We can also help you select the lip design and elastomer material based on the fluid being retained.
