The DBH 6554 radial shaft seal is a lip seal that is mounted in the housing and closes against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. With dimensions of 88.90 mm shaft, 126.95 mm housing bore and 12.70 mm height, and Lx design, it is a replacement part for equipment with shafts of that diameter. MR Accesorios Industriales supplies it as part of its line of seals and oil seals.

This item is a DBH 6554 radial shaft seal, identified by the designation 6554 and the manufacturer code 6554. Its dimensions are 88.90 mm shaft diameter (d), 126.95 mm housing bore diameter (D) and 12.70 mm height (h). The Lx design corresponds to a single-lip configuration with spring, suitable for rotating shafts. The elastomeric lip runs on the shaft and the outer metal case fits into the housing to maintain sealing.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where the shaft rotates inside a housing and oil or grease leaks must be prevented. It also appears in applications exposed to dust or splashes, where the seal protects the bearings and extends the life of the assembly. It is a wear part: when the lip hardens or the shaft is marked, it should be replaced to prevent lubricant loss.

To install it, verify that the shaft diameter and housing bore match the indicated values, that the shaft has no burrs or wear and that the sealing surface is clean. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it unevenly. If the equipment operates at high temperature or speed, consult the manufacturer's data sheet to confirm the lip material and spring type.

If you need an equivalent or a nearby size, send us the code 6554 or the dimensions of the old seal: shaft diameter, housing bore diameter and height. With that data we can look for an alternative within the DBH line or from other brands we supply. We can also guide you if the housing has a different recess or if the axial space is limited.
