This item is a radial shaft seal from the DBH brand, identified by the code 6221. Its dimensions are 12.5 mm shaft diameter (d), 25.53 mm housing diameter (D) and 5.78 mm height (h). The Lz design corresponds to a construction with a sealing lip and spring, suitable for rotating shafts. The seal is press-fitted into the housing and its flexible lip contacts the shaft to contain lubricant and block the ingress of dust or moisture.

It is used in equipment with rotating motion and the need to retain oil or grease. It appears in gearboxes, pumps, electric motors, compressors, spindles and transmissions. Also in automotive applications, agricultural machinery and industrial implements. Its compact size makes it common in small mechanisms, such as household appliances, power tools and precision equipment that require efficient sealing in a small space.

To select correctly, verify that the shaft, housing and height dimensions match those of the original seal. The Lz design must be compatible with the type of lubricant and the speed and temperature conditions. During installation, lubricate the lip, avoid damaging it with burrs and make sure the shaft has no splines or wear. Careful installation extends the seal's service life and prevents premature leaks.
