PTFE slide bearings offer versatile installation methods tailored to structural and movement requirements. Key approaches include bolting for adjustability, tack or full welding for permanence, and mortar embedment for concrete integration. Protection against contaminants like weld spatter is critical during installation, and these bearings are designed to be low-maintenance once properly installed.
Key Points Explained:
-
Primary Installation Methods
- Bolting: Ideal for applications requiring future adjustments or replacements. Uses threaded studs or bolts to secure the bearing, allowing disassembly if needed.
- Tack-Welding: Provides a semi-permanent bond with partial welds, balancing stability and potential removability.
- Full Welding: Creates a permanent, rigid connection for high-load or vibration-prone environments.
- Mortar Embedment: Used in concrete structures (e.g., bridges), where bearings are set into wet mortar for seamless integration.
-
Installation Nuances
- Protection During Installation: PTFE surfaces must be shielded from weld spatter, metal debris, and paints to prevent contamination that could impair sliding performance.
- Alignment: For flanged systems (e.g., valves), coaxial alignment is ensured via bolt holes, with clamping force applied evenly.
-
Material-Specific Considerations
- Contaminant Avoidance: Unlike traditional bearings, PTFE-lined types must avoid lubricants or oils, which can degrade performance.
- Low Maintenance: Once installed correctly, these bearings rarely need lubrication or frequent checks, though debris clearance is advised.
-
Method Selection Criteria
- Project Requirements: Permanent structures (e.g., bridges) may favor welding or embedment, while bolting suits adjustable systems.
- Movement Expectations: Tack-welding accommodates minor shifts, whereas full welding resists displacement.
-
Customization Potential
- For unique applications, custom PTFE parts can be tailored to specific installation constraints, such as non-standard bolt patterns or embedment depths.
By matching the method to structural demands and safeguarding PTFE integrity, these bearings deliver durable, friction-free performance across diverse engineering challenges.
