The DBH 6603Sil radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its designation indicates the main dimensions: 120 mm shaft diameter, 150 mm housing diameter and 12 mm height. It is a common replacement part in gearboxes, pumps and power transmission equipment that run on shafts of that size.
This DBH 6603Sil oil seal has a shaft diameter of 120 mm, a housing diameter of 150 mm and a height of 12.00 mm. The Lx design corresponds to a single lip configuration with spring, intended for rotating shafts with permanent lubrication. The flexible lip rides on the shaft and the outer body fits by interference in the housing, so the seal stays fixed while the shaft rotates. It is a component of the seals and radial shaft seals category, in this case from the DBH brand, a brand MR sells.
Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, large electric motors, rollers and belt or chain drive equipment. In all those cases it performs the same function: keeping oil or grease inside the housing and preventing the outside environment from contaminating the lubricant. It is also used as a barrier in equipment with washdown or dust exposure, where the seal works together with a bearing or a bushing.
To select and install the seal, check that the shaft diameter and the housing diameter match the values in the designation, and that the height is compatible with the housing depth. Inspect the condition of the shaft surface: a scratched or worn surface accelerates lip failure. During installation, lubricate the lip and use an insertion tool that presses on the outer edge, never on the lip. If the shaft has burrs, remove them before sliding the seal on.
To quote, send us the code engraved on the old seal and the dimensions measured with a caliper: shaft diameter, housing diameter and height. With that data we can locate the equivalent designation within the same series or propose a compatible alternative. If the original seal has no legible code, a photo of the housing and the shaft helps confirm the lip configuration and the material.
