For maintenance teams working on rotating equipment, the DBH 9849 radial shaft seal is a replacement wear part that keeps lubricant where it belongs and keeps contaminants out. It fits a 22 mm shaft, a 40 mm housing bore and a 10 mm width, and it presses into the housing of pumps, motors, gearboxes and similar assemblies. MR Industrial Accessories LLC supplies this brand and helps buyers confirm the correct reference before ordering.

The designation carries the sizing: shaft 22 mm, housing 40 mm, width 10 mm. The A 158 design is a single-lipped seal with a spring, intended for lubricated rotating shafts. In the DBH line, the 9849 number identifies this particular size within the range MR supplies. A quick caliper check of the shaft and bore before ordering avoids the most common mistake, since a seal that is slightly off will not seat or seal properly.

You will find this seal in centrifugal pumps, electric motors, gear reducers, gearboxes, compressors and transmission equipment, as well as in machine tools and process machinery where a shaft turns inside a crankcase. Its job in every one of those spots is the same: hold oil or grease in and keep dust, water and particles out, which protects the bearings and gears behind it. The compact dimensions make it a frequent choice on low- and medium-power units.

Selection comes down to shaft speed, operating temperature, lubricant type and differential pressure. The A 158 lip with spring suits moderate speeds and low pressures. When installing, coat the lip with the same oil the equipment uses, set the seal squarely in the bore and drive it in by tapping the outer circumference, never the lip. Confirm the spring faces the lubricant side.

If you need a cross-reference, send the full part number, a photo and your caliper readings. That is usually enough to match something in the same series or in another brand we carry. We can also advise when the housing bore differs or the shaft shows wear and a repair size makes more sense than a standard one.
