1. Easy to install, it can be stretched normally and held tightly onto the shaft by the elasticity of the rubber.
2. Low contact pressure at the lip and good wear resistance.
3. Allows for a certain degree of shaft eccentricity.
4. Effectively prevents the ingress of dust, powder, water, and their mixtures.
