A radial shaft seal such as the DBH 9321 keeps oil or grease where it belongs and keeps dust and water out. In this case the lip runs on a shaft measuring 17 mm, the outer diameter that presses into the housing is 45 mm, and the overall height is 7.00 mm, with the Lx lip design. You will find it on gearboxes, pumps, motors and other transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the size before you order.

Reading the reference: the 9321 designation identifies the seal, while the three figures describe the seat it fits. Shaft 17 mm, housing 45 mm, width 7.00 mm. The Lx design means a single lip with a spring, made for rotating shafts that run with lubrication. The lip rides on the 17 mm shaft, and the 45 mm outer diameter is press-fitted into the bore. Since it is a wear part, it should be swapped out as soon as leakage appears.

Seals in this size range show up on equipment with smaller shafts: electric motors, centrifugal pumps, gearboxes, reducers, compressors and machine tools, as well as agricultural implements and power transmission assemblies where lubricant has to stay separated from the surroundings. The job is always twofold: hold the oil or grease inside the bearing area and block contaminants such as dust, chips or wash water from getting in.

Installation notes. Inspect the 17 mm shaft for burrs or a worn sealing track, and make sure the 45 mm bore is clean and free of dents. Put some lubricant on the lip, then seat the seal straight rather than at an angle, using a tube or shim that bears on the outer diameter. Depending on the housing design, the 7.00 mm height should sit flush or slightly recessed. If the shaft already shows a pronounced groove, a repair sleeve is worth considering.

If code 9321 does not turn up or you need a comparable size, send the equipment data: shaft diameter, housing diameter and housing height. With those three figures we search the DBH line or another brand we carry. We can also advise whether a different lip design suits your case better when there is pressure, high peripheral speed or abrasive dust in the area. The more detail you provide, the quicker the answer.

MR Industrial Accessories supplies the DBH brand. If you already have code 9321, send it on WhatsApp with the quantity you need and we will prepare the quote. Unsure about the size? A photo of the old seal next to a caliper is enough for us to check it with you.
