A radial shaft seal from the DBH line, the 9030 keeps lubricant where it belongs and keeps dust and water out of rotating assemblies. Its working envelope is a shaft of 8 mm, a housing bore of 20 mm and a height of 7.00 mm, built in the Lx design. Seals of this size are easy to overlook, but when one lets go the lubricant is contaminated and bearings and bushings start wearing faster. MR Industrial Accessories supplies the 9030 as part of its seals and oil seals range.

The code breaks down simply: 9030 is the designation, and the three figures that matter for fit-up are shaft 8 mm, housing bore 20 mm and height 7.00 mm. The Lx configuration uses one sealing lip with a spring, which suits rotating shafts that run with lubrication. Because the DBH brand is one MR carries, the seal reaches you with its factory marking and traceability intact.

Typical service is an 8 mm shaft turning inside a 20 mm bore where the lubricant side has to stay sealed. You will find it in small electric motors, pumps, reducers, fans, machine tools and transmission equipment, and also in dirty settings where chips, dust or moisture are present and the oil inside needs protection. Maintenance departments and repair shops working on agricultural or process machinery come across it regularly.

Before pressing one in, confirm the shaft size and surface finish, and make sure the housing is clean with no burrs left behind. Fit the seal with the lip toward the lubricant and the front face square to the bore. Put a little lubricant on the lip first, then drive it with a tube or socket that contacts the metal edge only, never the lip. If the shaft is already worn, an offset-lip seal is worth considering.

For an equivalent, give us the number 9030 or the shaft, bore and height. We look through the DBH line and the other brands we supply. We can also tell you whether Lx is the right choice for your case, for instance when pressure or high speed is involved. Nothing gets bought on guesswork: the part is confirmed first, then quoted.
