The DBH 9255 oil seal is a single-lip radial seal designed for rotating shafts with a 20 mm diameter. It is mounted in 38 mm housings and has a 5 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings and bushings. It is a common wear part in electric motors, pumps, gear reducers and power transmission equipment, and is replaced when oil leakage or dirt ingress appears.

This DBH 9255 oil seal has a shaft diameter of 20 mm, a housing bore of 38 mm and a height of 5.00 mm. Its design is Lx, with a sealing lip and retaining spring. The lip works on the rotating shaft and the outer casing fits into the housing. The lip elastomer is formulated to resist industrial oils and greases, and the spring maintains contact pressure throughout its service life. It is used in equipment where axial space is limited.

Typical applications for this oil seal include electric motors, centrifugal pumps, speed reducers, gearboxes, compressors and belt or chain drive equipment. It is also found in machine tools, conveyors and process equipment where shafts rotate inside a lubricated housing. In all these cases, the seal prevents leaks and protects nearby bearings or bushings. It is a frequent replacement part and it is advisable to keep it identified by its code so it can be ordered without errors.

To select an oil seal correctly, check that the shaft, housing bore and height dimensions match those of your equipment's housing and shaft. Check the condition of the shaft surface: it must not have burrs, scratches or excessive wear in the lip contact area. When mounting, lubricate the lip with the same oil or grease used in the equipment, and insert the seal perpendicular to the shaft, without striking it from the side. If the housing has a chamfer, use it to guide the part. Poor alignment or a damaged lip causes premature leaks.

If you need an equivalent oil seal or a nearby size, have the code 9255 and the current dimensions on hand. We can look for alternatives within the DBH line or from other brands we supply, always respecting the shaft, housing bore and height dimensions. We can also guide you if the original seal has a special design, such as a double lip or a lip with a dust guard. The more data you give us — dimensions, type of lubricant, working temperature and application — the more accurate the proposal will be.
