The DBH 9257 is a radial shaft seal with a 24.5 mm shaft size and a 10.50 mm height. It keeps lubricant in and contaminants out of gearboxes, pumps, motors, and other rotating equipment. The A 181 lip profile and metal case define its geometry. MR Industrial Accessories supplies this seal and can help you confirm the right fit for your application.

This seal belongs to the DBH line and carries part number 9257. It is a single-lip, spring-loaded seal for rotating shafts. The listed dimensions are shaft 24.5 mm and overall height 10.50 mm. The A 181 designation describes the lip and case design. The housing diameter is shown as 0 mm, so that value should be verified against the manufacturer's technical data before you order.

Common uses include gearboxes, centrifugal pumps, electric motors, compressors, and power transmission equipment. In these assemblies, the seal performs two jobs: it retains oil or grease and blocks dust, water, and other particles. Because it is a wear part, plan to replace it when you see leaks or when the lip becomes hard, cut, or loses its flexibility. It also suits setups where axial space is tight and a compact seal is needed.

During installation, check that the shaft matches the specified size and that the contact surface is smooth and free of burrs. Apply a light coat of the same lubricant used in the equipment to the lip before pressing the seal into place. The 10.50 mm height must match the housing depth. If the housing is worn or damaged, consider a repair sleeve or a different seal size. Proper alignment between shaft and bore helps prevent early leaks and supports seal life.

To find an equivalent to the 9257, send the full part number, the shaft, housing, and height dimensions, and a photo of the old seal if available. With that information, we can search for an alternative in the DBH line or among other brands we carry. We can also advise you if the A 181 design is not the right match and a different lip profile is needed.
