详细信息
| 一、性能与用途 由一个低磨擦的填充聚四氟乙烯（ptfe）环和o形橡胶密封圈组合而成，o形圈提供足够的密封预紧力，并对ptfe环的磨耗起补偿作用。ptfe摩擦系数小，动静摩擦系数相近。适用于高低速往复运动及高压系统的油缸活塞杆密封。采用两个阶梯圈密封，可达到零泄露。一般要和导向环配套使用。轴径小于φ30的规格，应采用分体式沟槽。 二、材 质 阶梯圈为填充聚四氟乙烯ptfe，o形圈为丁腈橡胶nbr或氟胶fkm。 三、工况条件 耐 压：0-40mpa； 往复速度：≤5m/s； 工作温度：丁晴nbr：-30～+120℃，氟胶fkm：-20～+200℃； 工作介质：液压油、气、水（在磷酸酯液压油中选用氟胶)。 四、设计标准 本系列符合gb/t 15242.1-94及gb/t 15242.3-94标准。可参考parker公司od系列、merkel公司-oms-mr及霞板公司s55013系列。 五、标注方法 轴用阶梯圈用订货号来标注，示例：gsj-1000 ptfe+nbr 六、结构装置 |
