The DBH 6894Pol oil seal is a radial shaft seal with an A 023-R design that fits between a rotating shaft and its housing to retain lubricant and block the entry of dust, water or particles. Thanks to its dimensions —75 mm shaft, 100 mm housing and 12/13 mm height— it is used in gearboxes, pumps, motors and power transmission equipment. MR Accesorios Industriales carries this DBH reference within its seals and oil seals line.

This item is a DBH radial shaft seal identified as 6894Pol. Its dimensions are 75 mm shaft diameter, 100 mm housing diameter and a height of 12/13 mm, which indicates a double-height lip or a design with an integrated dust lip. It corresponds to the A 023-R design, a single-lip geometry with metal reinforcement. The code 6894Pol is DBH's commercial designation for this size, and it is advisable to verify that it matches the original part before replacing it.

Seals of this size are found in equipment where a 75 mm shaft rotates inside a 100 mm housing: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyors. Their function is twofold: keep the oil or grease inside the assembly and prevent contaminants from entering from the outside. In environments with dust, wash water or chips, the sealing lip works against a ground and lubricated shaft to maintain contact.

To install a seal, check the condition of the shaft: no burrs, no deep wear marks, and with adequate hardness and roughness. The housing must be clean, free of dents and with the correct diameter. It is recommended to lubricate the lip with the same grease or oil used in the equipment, insert the seal perpendicular to the shaft and press it in with a tube or spacer that rests on the outer ring, never on the lip. If the shaft shows a worn track, consider mounting the seal offset or using a repair sleeve.

If you need an equivalent or a nearby size, send us the code 6894Pol along with the shaft, housing and height dimensions, and the type of application. A photo of the old part or the housing drawing also works. With that data we look for the corresponding DBH reference or an alternative from another brand with the same geometry. If space allows, we can evaluate variants with an additional lip or dust lip.
