AI Technical Summary
During long-term operation, existing permanent magnet rollers are prone to powder accumulation on the bearing parts, resulting in poor sealing, reduced bearing life, and inconvenient maintenance.
A dust-proof structure was designed, consisting of a cylinder cover and a lower protective cylinder, connected by bolts to prevent dust from contacting the bearing. It is also equipped with a temperature sensor and a dust concentration sensor for real-time monitoring and convenient maintenance.
This effectively improves the service life of bearings and greatly enhances the efficiency of maintenance work, ensuring the reliability and ease of maintenance of bearings in harsh environments.
