When a pump, motor or gearbox starts weeping oil around the shaft, the usual suspect is the radial shaft seal. The DBH 5092Pol is a lip seal that sits between a rotating shaft and a stationary housing, holding lubricant in and keeping dust, water and particles out. Its dimensions are 22 mm shaft, 45 mm housing and 7 mm height, with the Lx design. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for your equipment.

Reading the code helps you order the right part. The 5092Pol designation identifies this particular size in the DBH line, while Lx tells you it is a single-lip seal with a spring, made for rotating shafts that run with oil or grease lubrication. The three numbers to verify before buying are shaft diameter (d) 22 mm, housing bore (D) 45 mm and height (h) 7.00 mm. If any of those differ from your application, the seal will not seat or seal correctly.

Seals in this size range show up in centrifugal pumps, electric motors, gearboxes, transmission shafts, mixers and process equipment, as well as in agricultural machinery and washing systems. Because it is a wear part, it makes sense to look at the lip, the spring and the seat whenever the equipment is opened up. Cuts, hardening or a lip that has lost its elasticity are signs that replacement is due.

Choosing the right seal comes down to a few variables: shaft speed, operating temperature, the lubricant being used and any differential pressure across the seal. The Lx design covers standard rotating-shaft duties with oil or grease. At installation, lubricate the lip, press the seal in with a tool that will not nick it, and make sure the spring faces the fluid side. A worn shaft may call for a seal with an auxiliary lip.

If you are not sure about the exact part, send code 5092Pol along with your shaft, housing and height measurements and a description of the application. A photo of the old seal or the marking on the part also helps. With that information we can review options in the DBH line and other brands we carry, and get you a quote.
