PTFE sliding bearing pads are essential components in bridge construction, designed to accommodate movement and reduce friction between structural elements. They come in two primary shapes—rectangular and circular—with dimensions typically ranging from 100mm to 800mm. These pads are engineered to handle vertical loads up to 5000KN, making them suitable for large-span bridges. Their unique properties, such as low friction and high shear capacity, ensure smooth sliding and durability under various environmental conditions.
Key Points Explained:
-
Shapes of PTFE Sliding Bearing Pads
- Rectangular: Commonly used in straight or right-angle bridges due to their alignment with linear movement.
- Circular: Preferred for skew or curved bridges, as they accommodate multi-directional movement more effectively.
- The choice between shapes depends on the bridge design and the direction of expected movement.
-
Dimensions and Load Capacity
- Sizes range from 100mm to 800mm in length or diameter, catering to different structural requirements.
- Designed to withstand vertical loads up to 5000KN, ensuring stability in large-span bridge applications.
- For more details on their specifications, refer to PTFE sliding pads.
-
Key Features and Benefits
- Low Friction Coefficient: PTFE’s ultra-smooth surface minimizes resistance, allowing seamless sliding.
- Shear Capacity: Handles lateral forces effectively, critical for dynamic bridge movements.
- Durability: Resistant to chemicals, UV radiation, and temperature fluctuations, ensuring long-term performance.
- Shock Absorption: Provides buffering and vibration isolation, protecting bridge structures.
-
Manufacturing Methods
- Two-Stage Process: Rubber bearings are made first, followed by PTFE plate molding and bonding.
- Integrated Vulcanization: PTFE grease pits are pressed during rubber vulcanization, reducing production steps.
-
Applications
- Ideal for large-span bridges, curved or skew bridges, and structures requiring rotational flexibility.
- Their adaptability makes them suitable for both new constructions and retrofitting projects.
By understanding these aspects, purchasers can select the right PTFE sliding pads for their specific project needs, balancing performance, cost, and longevity.
