The DBH 8270Sil is a radial shaft seal designed to keep lubricant in and contaminants out where a rotating shaft passes through a housing. Its published size is 17 mm at the shaft, 30 mm at the housing and 7.00 mm in height, and it carries the Lx design. MR Industrial Accessories supplies this seal and can help you confirm the right fit before you order.

In the DBH line, this part is listed as 8270Sil. The three dimensions to check first are shaft 17 mm, housing 30 mm, width 7.00 mm. The Lx designation refers to a single lip with a spring, a common choice for lubricated rotating shafts. The elastomeric lip rides against the shaft while the metal case holds the seal in the housing. Because it is a wear part, it is normally replaced once leakage or contaminant entry shows up.

You will find this seal in gearboxes, centrifugal pumps, electric motors, reducers and other power transmission assemblies. There it keeps oil or grease where it belongs and shields bearings from dust and moisture. Machine tools, compressors and conveyor systems are other places it turns up. Before fitting a new seal, inspect the shaft for wear or marks that could harm the lip.

Installation starts with a clean housing and shaft, no burrs, and a lip lubricated with the same oil the equipment uses. Press the seal in squarely, using a tube that contacts the case rather than the lip. Shaft speed, temperature and lubricant type all affect selection. If the shaft surface is damaged, a wear sleeve is worth considering. The Lx design suits general duties at low pressure.
