品牌: 瑞典特瑞堡TRELLEBORG（原宝色霞板Busak+Shamban）
品名: 德国DUALSEAL 哑铃圈
说明
在目前的液压缸设计中，O-形圈或O-形圈/挡圈组合主要用作静态密封件，但是，这种密封解决方案在装配时有的风险，因为O-形圈有可能扭曲，挡圈的位置有可能不是佳。这种解决方案在有压力脉动和脏物侵入的情况下也表现出缺点。在这种情况下，哑铃形密封件作为单个元件的静态液压密封件，可以作为理想的替换品。
优点
和O-形圈/挡圈组合相比较，复式密封件具有以下的
优点:
- 非常耐扭曲
- 便于安装
- 使用寿命长
- 材料非常耐挤压
技术数据
工作压力: 高50 MPa
工作温度: -35°C至+110°C
材料
标准材料: Zurcon Z20聚氨酯橡胶，邵氏A 93，青
绿色。适用于所有的HL和HLP液压油。特殊用途:
