陶瓷托輥
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，降低卷揚驅動力，延長輸送帶的使用壽命。軸承采用特殊封閉結構，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. .
