This item is a radial shaft seal of the DBH brand, identified with part number 8144. Its dimensions are 85.73 mm for the shaft diameter, 114.26 mm for the housing diameter and 15.87 mm total height. The Lz design corresponds to a single-lip configuration with spring, intended to retain oil or grease in applications where the shaft rotates and the cavity is machined to receive the seal. The 8144 nomenclature allows it to be quickly located in catalogs and cross-reference systems.

Typical applications of a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the function is the same: keep the lubricant inside the assembly and prevent dust, water or external particles from entering the bearings or gears. It is a wear part that should be replaced when leaks appear or when stiffness or noise is detected during rotation.

To correctly install this oil seal, verify that the shaft diameter and the housing match the indicated dimensions. The shaft surface must be clean, free of burrs or deep marks, and it is advisable to lubricate the lip before inserting it. The seal is installed with the lip facing the side of the fluid to be retained, using an installation tube that rests on the outer ring, never on the lip. If the housing shows wear, consider using a seal with a sleeve or an alternative size.

If you need an equivalent or a neighboring size, the most practical thing is to send us part number 8144 or the current dimensions on WhatsApp. With that data we can look for alternatives in other brands or series that keep the same shaft and housing diameter, adjusting the height if space allows. We can also advise you on the type of lip and material according to the fluid and working temperature. MR Accesorios Industriales has more than 80 years supporting industry with sealing solutions.
