A radial lip seal like the DBH 9241Pol keeps lubricant where it belongs and contamination out, sealing the gap where a rotating shaft exits a housing. This one carries a 58 mm shaft size, 74 mm housing size and 8 mm height, and follows the A 145 design. It presses into crankcases, covers and similar bores, and it is a wear item: once it drips or the machine comes apart, replacement is the practical move.

Reading the code and the numbers first saves a return. On the DBH 9241Pol the bore it presses into measures 74 mm, the shaft it rides on measures 58 mm, and the overall width comes to 8 mm. The A 145 designation describes the lip geometry and the metal case. Fit depends on interference in the housing plus lip contact on the shaft, so a worn shaft or a distorted bore will leak even when the size is correct.

Typical locations include gearboxes, pumps, electric motors, transmission shafts and process equipment, plus road and agricultural machinery and production lines where dust or water is present. In every case the job is the same: hold oil in, keep contaminants out, and protect the bearing or gear behind it. Compared with the cost of a lubrication-related failure, the seal itself is a minor expense.

Selection goes beyond the three measurements. Lip compound, the fluid being sealed and the operating temperature all matter, and the A 145 design tells you the lip and spring configuration. During installation, coat the lip, press the seal in square, and apply force to the outer edge rather than the lip. Inspect the shaft contact zone for burrs or grooves, since either one will shorten the time before a leak appears.

To get a quote on the 9241Pol, send the code along with shaft, housing and height dimensions and a photo of the removed seal. From there we can match it in the same brand or find a comparable option from another line we carry, and help you confirm that size and material suit the application.
