陶瓷托辊
陶瓷托辊硬度大、高耐磨、耐腐蚀、表面光滑、不粘附物料，与输送带接触摩擦系数小，降低卷扬驱动力，延长输送带的使用寿命。轴承采用特殊封闭结构，两端装有注油嘴，可定期润滑保养，尤其试用于恶劣环境下使用。实践证明：陶瓷托辊比一次性铁辊使用寿命长3-5倍，是目前带式输送机的理想换代产品。
Porcelain support roller
Porcelain support rollers have
characteristics of high hardness, high wearing, corrosion resistance, smooth
surface and non-stick material. Small contact friction coefficient with the
conveying belt and lower winding driving force make a longer service life of
the conveying belt. Bearing adopts special enclosed construction with grease
nipples at both ends, and you can make time-based lubrication maintenance, especially
used in severe atmosphere. Practice has proved that: compare with the
disposable iron roller, the porcelain support roller have 3-5 times service
life. Present it is the ideal replacement product of belt conveyor. .
