The DBH 8118 radial shaft seal is a lip seal mounted in the housing that seals against the rotating shaft to retain lubricant and stop the entry of dust, water or particles. Its dimensions are 17 mm shaft, 28.50 mm housing and 6 mm height, with Lx design. It is used in gear cases, pumps, electric motors and power transmission equipment where bearings and gears must be protected. MR Accesorios Industriales carries it as an official brand.

This item is a seal from the DBH line, identified with the code 8118. Its nominal dimensions are 17 mm shaft diameter (d), 28.50 mm housing diameter (D) and 6.00 mm height (h). The Lx design defines the geometry of the lip and the outer body. It is a radial single-lip seal, intended for rotating shafts with permanent lubrication. The elastomer of the lip works on the shaft race and the rigid body fits into the housing by interference. Always confirm these dimensions against the manufacturer's product page before installing.

Typical applications of a seal of this size appear in equipment with shafts up to 17 mm: small gear cases, centrifugal pumps, low-power electric motors, gearboxes, mixers and machine tools. It is also found in power transmission equipment where oil or grease must be separated from the environment. In all those cases the function is the same: keep the lubricant inside and the contaminants outside, extending the life of bearings and gears.

To select the correct seal, verify that the shaft diameter, the housing diameter and the height match the values of the part. Check the condition of the shaft race: if it has scratches, wear or burrs, the lip does not seal properly and it is advisable to repair or replace the shaft. During installation, lubricate the lip with the same grease or oil as the equipment, insert it perpendicular to the shaft and avoid striking it. The Lx design orients the lip in a specific way; if the old seal has another shape, compare the profile before replacing it.
