The DBH 8126 oil seal is a single-lip radial shaft seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Due to its dimensions of 56 mm shaft, 85 mm housing and 10/11 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment operating at moderate speeds. MR Accesorios Industriales supplies it as part of its line of seals and oil seals.

This oil seal corresponds to designation 8126 and design A 101, with a sealing lip that bears on the shaft. The dimensions listed on the data sheet are: shaft diameter 56 mm, housing diameter 85 mm and height 10.00/11.00 mm. This dual height indicates that the seal can be fitted in housings with a depth of 10 or 11 mm without modifying the seat. The lip is reinforced with a steel spring that maintains contact pressure on the shaft.

It is used in equipment where there is a rotating shaft coming out of a crankcase or a housing: speed reducers, centrifugal pumps, electric motors, mixers, conveyors and machine tools. It also appears in agricultural and industrial applications where oil or grease must be contained and contaminants kept out. It is a wear part that should be checked when there are lubricant leaks or noise in the bearing area.

To install it, check that the shaft has the 56 mm dimension and suitable roughness, free of burrs or marks that could damage the lip. The 85 mm housing must be clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a tool that bears on the outer edge, never on the lip. The 10/11 mm height allows you to choose the position according to the available space. If the shaft shows wear, consider a seal with an offset lip or a repair sleeve.
