The DBH 9256 is a radial shaft seal that keeps oil or grease where it belongs on a rotating shaft, blocking leaks and keeping dust and water out. Its A 154 configuration pairs a sealing lip with a metal outer body that presses into the housing. You will find this type of seal in gearboxes, pumps, electric motors and power transmission equipment, where a failed seal means lubricant loss and unplanned downtime.

The dimensions to check before ordering are shaft 31 mm, housing 52.40 mm, and height 15.50/10.00 mm. The A 154 designation refers to a lip seal with a reinforced body designed for press fitting into a machined bore. MR supplies this seal under the DBH brand as part of its radial seal range. Because the height is stepped at 15.50/10.00 mm, the seal can sit at different depths depending on how the housing is machined.

Common installation points include gearboxes, reducers, centrifugal pumps, electric motors and other power transmission drives. In each case the seal retains lubricant and shields bearings and gears from outside contamination. You will also see it on agricultural machinery, material handling equipment and hydraulic systems where a shaft turns inside a fixed housing. The A 154 design suits moderate peripheral speeds and continuous duty.

When selecting a replacement, confirm the shaft measures 31 mm and the housing bore 52.40 mm. Match the mounting height to the space available, whether that is 15.50 mm or 10.00 mm. Keep the lip lubricated and free of nicks, and use a proper installation tool to avoid distorting the seal. If the shaft is worn or rough, look at options such as an auxiliary lip or a wear sleeve. Clean both housing and shaft before pressing the seal in.
