SIL 型密封为聚氨酯 U 型活塞杆密封（图 1），采用醚基 TPU 制成。具有双密封唇设计和动密封副唇。这种密封具有良好的耐水解性（防水分侵蚀）和良好的低温回弹性。SIL 型密封适用于压力达到 350 bar (5075 psi) 的轻载到中载应用，并提供公制尺寸产品。某些产品适用于符合 ISO 5597:2010 标准的密封沟槽。
液压杆后跟 U 型杯密封
这些液压杆密封采用带有辅助动态密封唇的无载荷的 U 型杯设计。 它们由乙醚基热塑性聚氨酯制成，对于水解（湿气侵蚀）具有较高的耐受性，具有较强的耐低温性能。
- 性能适合符合 ISO 5597 的密封轴承座
- 能承受高达 350 bar (5 075 psi)压力
- 适合低温和中低载荷应用
- 可选公制尺寸
