陶瓷托輥

陶瓷托輥硬度大、高耐磨、耐腐蝕、表面光滑、不粘附物料，與輸送帶接觸摩擦系數(shù)小，降低卷揚驅(qū)動力，延長輸送帶的使用壽命。軸承采用特殊封閉結(jié)構(gòu)，兩端裝有注油嘴，可定期潤滑保養(yǎng)，尤其試用于惡劣環(huán)境下使用。實踐證明：陶瓷托輥比一次性鐵輥使用壽命長3-5倍，是目前帶式輸送機的理想換代產(chǎn)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. .
