The DBH 9118 is a radial shaft seal that keeps oil or grease contained where a rotating shaft passes through a housing, such as in gearboxes, pumps and motors. Its Lx design pairs a main sealing lip with a secondary dust lip that shields the contact zone. The dimensions are shaft 30 mm, housing 47 mm and height 7.00 mm, a size that appears often in power transmission equipment. MR supplies this seal as a brand item.
The numeric code 9118 identifies this radial shaft seal. The data on the product page gives a shaft diameter of 30 mm, a housing bore of 47 mm and a height of 7.00 mm. In the Lx design, a primary lip does the sealing and an additional exclusion lip keeps dust and dirt away from the contact area. The elastomer compound and the internal spring are checked against the manufacturer's data sheet when a quote is prepared.
This seal suits equipment that runs continuously and must hold lubricant in place: gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission components. It also shows up on road and agricultural machines and in process lines built around a 30 mm shaft. Where dirt or chips are present, the dust lip of the Lx design helps the seal keep working as intended.
During installation, confirm the shaft has the right hardness and surface finish, and that the housing bore is clean and free of burrs. Press the seal in with a press or a support tube; never hammer on the lip. Lubricate the lip with the same oil or grease used in the equipment before fitting it. If the shaft is worn, an oversized repair size or a seal with an offset lip may be an option. Speed, temperature and the fluid being retained all influence the final choice.
To quote an equivalent to the 9118, send the complete part number, the shaft, housing and height dimensions, and a photo of the old seal if available. With those details we can search other brands or our own product line where applicable. We can also tell you whether the Lx design fits your application.
