The DBH 8166Sil radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and stop the entry of dust, water or particles. With dimensions of 17 mm shaft, 35 mm housing and 7 mm height, and Lx design, it is a common replacement part in rotating equipment. MR Accesorios Industriales carries it as part of its line of seals and shaft seals.

This item is a DBH 8166Sil radial shaft seal, identified by its exact designation and by the dimensions shown on the product page: 17 mm shaft diameter, 35 mm housing diameter and 7 mm height. The Lx design corresponds to a single-lip configuration with a spring, intended for rotating shafts with lubrication. The DBH brand is a brand that MR carries, and code 8166Sil allows it to be located without ambiguity within the seals and shaft seals category.

Typical applications for a seal of this size appear in pumps, electric motors, gearboxes, compressors and transmission equipment where there is a shaft rotating inside a housing and the oil needs to be separated from the environment. It is also used in machine tools, agitators and conveyors. In every case it performs two functions: preventing lubricant leaks to the outside and blocking the entry of contaminants toward the bearings or gears.

To install it properly, verify that the shaft has no burrs or wear in the contact area and that the housing is clean and free of deformation. The seal is inserted perpendicular, with a suitable tool, until it seats at the bottom. Before fitting it, lubricate the lip with the same grease or oil used in the equipment. If the shaft shows a marked groove, it is worth evaluating a different shaft size or a design with an auxiliary lip.

If you need an equivalent, the most practical approach is to send code 8166Sil along with the shaft, housing and height dimensions, and a photo of the old part if you have it. With that data it can be compared against other options in the same category and design compatibility can be verified. Not all sizes are interchangeable: the shaft diameter and height must match for the seal to seal correctly.
