The DBH 9489/85 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain oil or grease and block the entry of dust and water. With dimensions of 19 mm shaft, 38 mm housing bore and 7 mm height, and A 100 design, it is a replacement part for equipment with small-diameter shafts. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

This DBH 9489/85 seal has a shaft diameter of 19 mm, a housing bore diameter of 38 mm and a height of 7.00 mm. Its A 100 design corresponds to a radial shaft seal with a single lip and spring, intended for rotating shafts with permanent lubrication. The 9489/85 nomenclature identifies the geometry and lip compound within the DBH line. It is a replacement part selected by dimensions and type of service, not by machine serial number.

It is used in small gearboxes, electric motors, centrifugal pumps, compressors, fan shafts and power transmission equipment where a 19 mm shaft must be sealed. It also appears in machine tools, washing equipment and pumping systems that operate with oil or grease and need to contain the lubricant and prevent contaminant ingress. It is a critical component in preventive maintenance: replacing it in time prevents leaks and premature bearing wear.

To install it, check that the shaft is clean, with no burrs or marks, and that the housing bore has no dents. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal with an installation tube that presses on the outer diameter, never on the lip. The 7.00 mm height must match the depth of the housing bore. If the shaft shows wear, consider a nearby size or a seal with the lip in a different position. Speed and operating temperature depend on the compound, which is confirmed against the manufacturer's data sheet.

If you need an equivalent or a different size, send us the code 9489/85 along with the shaft, housing bore and height dimensions, and the type of fluid and operating temperature. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also advise you if the original seal is not available and a close size has to be adapted. The more complete the information, the more accurate the proposal.
