Characteristics of Bearing Types in Dusty Environments

Xiangye Editor introduces the characteristics of dust-bearing types: mainly including roller-type rolling bearings and integral sliding bearings. In roller-type rolling bearings, the two-wheel type cannot withstand upward force and is only suitable for downward force applications; the three-wheel and four-wheel types can be used in scenarios with both downward and upward forces. The integral sliding dust-bearing has a simple structure, is cast as a whole, and is suitable for various force conditions.

 • Dust-proof design: Some dust-bearings are equipped with soft dust-proof fabric on both sides of the integral bearing, with clamps applied outside the fabric to prevent or reduce dust from entering the bearing hole, thereby reducing wear and extending service life. • Installation and maintenance: The structural design of dust-bearings allows all components to be easily and quickly assembled and disassembled, making installation, repair, and replacement very convenient. During maintenance, regular cleaning is required to remove surface-adhered particles. After cleaning, anti-rust grease should be applied immediately. Additionally, weight, dimensions, and rotational accuracy should be checked regularly, and replacement is necessary if standards are not met.

Working Principle

The working principle of dust-bearings is as follows:

Through the design of components such as rollers and supports, dust-bearings can function in electrostatic precipitators to secure the rapping shaft and prevent misalignment and bouncing.

Their special structural design helps extend service life and facilitates installation, repair, and replacement.

In theory, dust-bearings do not serve a transmission function and may even interfere with it. Therefore, ensuring good lubrication on high-speed shaft bearings is essential.
