The DBH 6731 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With dimensions of 120 mm shaft, 145 mm housing and 15 mm height, and Kx design, it is used in gearboxes, pumps, electric motors and power transmission equipment running on shafts of that diameter. MR Accesorios Industriales supplies it as part of its seals line.

This item is a seal from the DBH 6731 series, with the following dimensions: shaft diameter 120 mm, housing diameter 145 mm and height 15.00 mm. The Kx design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The code 6731 identifies the exact combination of dimensions and design within the DBH line, and it is the data you need to provide so we can confirm the part without ambiguity.

Seals of this size are found in equipment where the shaft rotates at medium speeds and oil or grease is present: gearboxes, centrifugal pumps, medium-power electric motors, conveyor rollers and machine tools. They also appear in applications where the environment has dust or moisture and an additional barrier is needed besides the lubricant. If the equipment runs with vibration or misalignment, it is advisable to check the condition of the shaft and housing before replacing.

To correctly select a seal, verify that the shaft diameter, housing diameter and height match those of your equipment's housing and shaft. The Kx design defines the lip type and material, but it does not replace verification of peripheral speed or working temperature. During installation, lubricate the lip, avoid striking it and make sure the shaft has no burrs or marks that could damage the seal. If the shaft is worn, consider a repair sleeve.
