The DBH 6018 is a radial shaft seal designed to retain lubricant and block contaminants in rotating equipment. It features a single lip with a spring, known as the Mz design, and its dimensions are 63.50 mm shaft, 98.45 mm housing, and 11.90 mm width. This seal is a direct replacement for assemblies with matching cavity and shaft sizes.

As a dynamic sealing element, the DBH 6018 combines an elastomeric lip that rides on the shaft with a metal case that presses into the housing. The Mz designation indicates a single-lip configuration with a garter spring, suitable for lubricated rotating shafts. It is not a structural part; its role is to keep oil or grease in and keep dust, water, and particles out.

Seals of this size are commonly found in gearboxes, pumps, electric motors, mixers, and transmission units where a shaft rotates within a fixed housing. They also appear in conveyors, agricultural equipment, and process machinery exposed to dust or moisture. In every case, the objective is to protect bearings and gears from premature wear caused by leakage or contamination.

Selection depends on matching three dimensions: shaft 63.50 mm, housing 98.45 mm, and width 11.90 mm. Confirm these against your equipment before ordering. Inspect the shaft surface for burrs, scratches, or deep marks, as the lip must seal against a smooth track. During installation, lubricate the lip with the same oil or grease used in the assembly, press the seal perpendicular to the shaft, and avoid hitting it directly. If the shaft is worn, a repair sleeve may be needed.

If the 6018 code is not available or you require a different size, provide the shaft, housing, and width dimensions, along with the design type if known. Our team can cross-reference the DBH line or other brands we supply. We can also advise whether a slightly different height or diameter is acceptable for your housing. Accurate information helps us identify the correct part quickly.
