Sealing a rotating shaft comes down to matching three measurements, and the DBH 9107 covers the common 22 x 45 x 8 mm combination. It is a single-lip radial shaft seal with an Lx configuration, meaning a sealing lip carried on a metal body. The lip rides against the shaft while the outer diameter holds by interference in the housing, so lubricant stays in and outside contamination stays out. Typical hosts are gearboxes, pumps, motors and power transmission drives. MR Industrial Accessories supplies this brand and helps you confirm the size before you order.

Reading the code is straightforward. The designation 9107 identifies this seal, and the numbers that follow in a catalog line describe the fit: shaft 22.00 mm, housing 45.00 mm, height 8.00 mm. In other words, the shaft it seals measures 22.00 mm across, the bore that receives it measures 45.00 mm, and the seal sits 8.00 mm deep in the housing. The Lx design adds the lip-plus-metal-body construction. Get any of those three figures wrong and the seal will either leak or refuse to seat.

These proportions turn up across a wide range of rotating equipment: gear reducers, centrifugal pumps, electric motors, conveyor rollers and other transmission assemblies. In every case the job is the same, keeping oil or grease where it belongs and keeping dust, water and particles out of the bearing cavity. Because the lip runs continuously against the shaft, the seal is a wear item. Dripping, unusual noise or shaft movement are the usual signals that it is time to replace it. Agricultural and road machinery use the same size frequently.

Selection starts with your own hardware, not the catalog. Measure the shaft, the housing bore and the depth, then compare them with the figures above. The shaft surface should be ground and free of grooves or burrs, and the housing should be clean and undistorted. When you press the seal in, coat the lip with the same oil the equipment runs on and slide it over a support tube so the lip is not rolled or cut. A worn shaft may call for a repair sleeve or a different size.

If the exact size is not listed or you need a substitute, send the code 9107 or your three measurements on WhatsApp. The MR team searches within the same radial seal category and can also advise on lip type and material based on the fluid and the operating temperature. Quotes go out by WhatsApp or email with the options that fit your equipment.
