PTFE-lined bearings are engineered for high-performance applications where low friction, durability, and load capacity are critical. Their specifications include a coefficient of friction ranging from 0.02–0.20 (dry) to 0.02–0.15 (oiled), maximum sliding speeds of 2.5 m/s (dry) and 5 m/s (oiled), and impressive load capacities of 250 N/mm² (static) and 140 N/mm² (dynamic). Proper bonding of the PTFE liner is essential to prevent failure, emphasizing the need for experienced manufacturers. These bearings are ideal for demanding environments, offering reliability and efficiency.
Key Points Explained:
-
Coefficient of Friction
- Dry Conditions: 0.02–0.20
- Oiled Conditions: 0.02–0.15
- Why It Matters: Lower friction reduces energy loss and wear, making PTFE-lined bearings suitable for precision applications.
-
Maximum Sliding Speeds
- Dry: 2.5 m/s
- Oiled: 5 m/s
- Why It Matters: Higher speeds are achievable with lubrication, expanding their use in dynamic systems like automotive or industrial machinery.
-
Load Capacities
- Static: 250 N/mm²
- Dynamic: 140 N/mm²
- Why It Matters: High load capacity ensures reliability under heavy stress, critical for construction or aerospace applications.
-
Manufacturing Considerations
- Proper bonding of the PTFE liner is crucial to avoid separation and failure.
- Experienced manufacturers, like those producing ptfe lined cap, ensure optimal performance and longevity.
- Why It Matters: Poor bonding can lead to rapid degradation, compromising safety and efficiency.
-
Applications
- Ideal for harsh environments (e.g., chemical exposure, high loads).
- Used in industries like automotive, aerospace, and heavy machinery.
These specifications make PTFE-lined bearings a top choice for engineers prioritizing performance and durability.
