The DBH 9512/85 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. Its function is to retain lubricant inside the assembly and stop the entry of dust, water or particles. It is press-fitted into the housing and runs on the rotating shaft, with a flexible lip that compensates for small misalignments and vibrations inherent to operation.

This item is a DBH radial shaft seal with the designation 9512/85, with the following dimensions: shaft diameter 28 mm, housing bore 38 mm and height 6.50 mm. The Lt design corresponds to a single-lip configuration with a spring, suitable for rotating shafts with permanent lubrication. The sealing lip bears on the shaft and the outer case maintains the necessary interference in the housing to prevent rotation and leakage.

Seals of this type are used in gearboxes, pumps, electric motors, compressors, machine tools and transmission equipment. They also appear on fan, mixer and conveyor shafts, where the lubricant must be contained and the bearings protected from the environment. In each case, the seal works alongside a bearing or bushing that needs clean oil with no losses to support the load and the design speed.

To choose correctly, check that the shaft diameter and the housing bore match the values on the product page. The shaft must be ground, free of burrs and marks, with adequate hardness and roughness so as not to cut the lip. During installation, lubricate the lip with the same grease or oil used in the machine, insert the seal perpendicular to the shaft and apply force on the outer ring, never on the lip. If the housing has a shoulder, respect the depth so that the seal sits flush or as shown on the drawing.

If you need an equivalent, send us the code 9512/85 together with the shaft, housing and height dimensions, and the type of lubricant. A photo of the old seal or the housing drawing also helps. With that data we review alternatives within the DBH line and other brands we carry, always confirming dimensions and design against the manufacturer's data sheet before quoting.
