通过对某冷轧设备支撑辊轴承密封系统失效原因的分析，提出一种由防尘防垢密封、金属迷宫密封、骨架水封和骨架油封构成的组合密封方案，其中防尘防垢密封可防止外部乳化液、冷却水进入支撑辊；骨架水封与支撑环起到封油和防水、防切削液等进入的作用；骨架油封可有效防止密封内部油液的泄漏。改造后的密封系统密封效果良好，使用寿命大大延长。
通過對某冷軋設備支撐輥軸承密封繫統失效原因的分析，提齣一種由防塵防垢密封、金屬迷宮密封、骨架水封和骨架油封構成的組閤密封方案，其中防塵防垢密封可防止外部乳化液、冷卻水進入支撐輥；骨架水封與支撐環起到封油和防水、防切削液等進入的作用；骨架油封可有效防止密封內部油液的洩漏。改造後的密封繫統密封效果良好，使用壽命大大延長。

Through the analysis of failure reasons of a supporting roller bearing sealing system for cold rolling equip-ment,a combination sealing solution composed of dustproof and anti-fouling seal,metal labyrinth seal,skeleton water seal and skeleton oil seal was proposed.The dustproof and anti-fouling seal can prevent external emulsion and cooling water en-tering the support rollers,the skeleton water seal and support ring act as sealing oil and preventing the water and cutting fluid entering the support rollers,and skeleton oil seal can effectively prevent the internal oil leakage.After transformation, the sealing system has good sealing effect,and service life is greatly extended.
