The DBH 1297 radial shaft seal is a lip seal designed to close off the passage of oil or grease in rotating equipment, preventing leaks and the entry of dust or water. It is mounted on the shaft and inside the housing, with the height defining its axial position. It is a wear part that should be replaced when lubricant loss or contaminant ingress appears. MR Accesorios Industriales carries this brand and helps you identify the correct size.

This item is a DBH 1297 radial shaft seal with dimensions of 133.40 mm shaft diameter, 165.10 mm housing diameter and 15.90 mm height. The Kx-R-H design indicates a configuration with a retaining lip and reinforced body for service under demanding conditions. The designation 1297 corresponds to the manufacturer's code and should not be confused with inch dimensions or other series. If your equipment calls for this reference, the three dimensional values are what define compatibility.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing. It also appears in agricultural machinery, industrial washing equipment and conveying systems. In all cases it performs the same function: retaining lubricant and stopping the ingress of particles. The choice of lip material and spring depends on the fluid and working temperature, data worth having on hand when consulting.

To install it, verify that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before inserting it and seat the part perpendicular to the shaft so as not to deform it. If the previous seal failed due to heat or contamination, also check the condition of the bearing and the lubricant. Selection is defined by the d, D and h dimensions, the type of fluid and the shaft speed; with that data it is confirmed whether the Kx-R-H design is the right one.

If you cannot find the exact reference or need a nearby size, send us the code 1297 along with the shaft and housing dimensions. A photo of the old part or the assembly drawing also works. With that data we look for an equivalent within the same brand or another line that performs the function. You do not need to have the part number: the dimensions and intended use are enough to guide the search.

MR Accesorios Industriales carries the DBH brand and brings more than 80 years of experience in bearings, power transmission and sealing. If this seal is for your equipment, write to us on WhatsApp with the code 1297 or with the dimensions and we will send you the quote. We can also review whether a seal with a different lip geometry or a different material is better suited to the fluid. The idea is that you ask once and receive the correct part.
