For low-speed rotating shafts, O-rings can usually be selected as sealing rings. O-ring is the most common kind of sealing ring, its shape is a ring, with good sealing and wear resistance. On rotating shafts, O-rings are usually used for static seals and dynamic seals on low-speed rotating shafts. Its outline is round, the assembly is relatively simple, and there are a variety of materials to choose from, such as butyl rubber, silicone rubber, fluorine rubber, etc., to adapt to different working environments.
However, it should be noted that different working conditions have different requirements for rotating seals, so it is necessary to choose the appropriate specification model to ensure the sealing effect and service life. When choosing, factors such as speed, size and material need to be considered. For example, if the shaft has a high speed, you may want to consider using a U-ring or other sealing ring that is better suited for high-speed rotation.
In general, for low-speed rotating shafts, O-rings are a common choice, but the specific choice needs to be considered according to the specific working environment and requirements.
