Floating oil seals are classified according to the width of the bright band on the working surface

(1) Narrow bright band type

The width of the bright band on the working surface of this type of floating oil seal is only 0.2~0.3mm. Its advantage is that grinding the bright band is simple and time-saving. However, the requirements for the concentricity of the floating ring are relatively high, and leakage will occur when the concentricity exceeds the tolerance during operation. Oil.

(2) Wide bright band type

The width of the bright strip on the working surface of this type of floating oil seal is relatively wide, and its width can reach 1.5~2.5mm. The advantage is that the concentricity requirements are not high when the floating ring parts are assembled in time, and the sealing performance is better. However, grinding the bright strip is time-consuming. Effortless.
