There are several main types of sealing structures for roller supports.

Maze sealing: This type of sealing has a longer operating time and good dust-proof performance, making it suitable for high-speed operation.

There are three main forms of roller seal structures:

(1) Labyrinth seal: This sealing form has a longer operating time and good dust-proof performance, suitable for high-speed operation. However, its water resistance is poor, especially in low-temperature environments, where the rotation increases significantly, making it unsuitable for use.

(2) Contact seal: This sealing form has excellent waterproof and dust-proof effects, but it has high operating resistance and allows for extreme tilt, making it unsuitable for high-speed operating conditions.

(3) Combination seal: A combination of two or more seals. It has good sealing effects and is currently widely used.
