Aohong manufactures high-performance PTFE Bearing Pads designed to provide low-friction sliding surfaces for bridge structures and heavy engineering projects. These pads combine laminated rubber layers with a bonded polytetrafluoroethylene (PTFE) sheet, offering excellent flexibility, rotational capacity, and horizontal displacement control. The dimpled PTFE surface, filled with lubricant, significantly reduces friction, allowing smooth expansion and contraction movements in bridge superstructures. Widely used in highway bridges, continuous beam bridges, and large-span structures, PTFE Bearing Pads meet EN 1337-2 and other international standards.

结构成

PTFE 环形板由多层天然或新橡胶、加固钢板和保合的PTVE滑动表面组成。, 通常为1. 5毫米至3毫米厚,设计时装有大便,以保留润滑油,确保稳定滑动和提高耐久性。, 压层设计提供垂直硬度,支持重负载重,同时允许横向灵活性,以适应地震或热, 流动。

PTFE 嵌入斜面的特性

• 平稳滑动的低摩擦系数。
• 垂直载荷容量高,横向流离失所情况极佳。
• 执行的PTFE层为延长性能保留润滑剂。
• 适合横梁端的旋转和剪切移动。
• Resistant to temperature variations from -40°C to +60°C.
• Complies with BS EN 1337-2 and other bridge engineering standards.
