1.1Product Introduction：
1. The design of precision ball bearing and inner and outer cover constitutes the key bearing assembly part. It is not only beautiful, but more importantly, it makes the roller run more quietly;
2. The end cover of the roller head effectively prevents the entry of dust and splashing water in the working environment;
3. The design of the bearing assembly makes it capable of working in a certain special environment;
4. The lubrication method of the bearing can be flexibly configured with oil lubrication or grease lubrication according to the needs;
5. Suitable for high-speed conveying, the speed will vary according to the diameter and length of the roller, the maximum can reach 120m/min;
6. Operating temperature: -5~＋40℃
