Q: Why do we use a shields(ZZ) bearing?
A: The bearing of the iron cover has many uses, the main function is to prevent dust. The speed of the iron cover is higher. But because it is made of iron, it is not waterproof, but the rubber cover has greater friction, so the heat dissipation performance is also worse than that of the iron cover. And in terms of speed, the rubber cover is also lower than the iron cover. The temperature of the bearing is generally not higher than 150 ℃.
Stamping steel plate bearing dust cover: structure to reduce the leakage of grease, and to strengthen the metal steel plate on the outer ring by stamping.
