Market Challenges
Thermal and Chemical Limitations:
Plastic cages generally have lower operating temperature limits (typically 120°C for PA66) compared to steel. While PEEK can handle higher temperatures (up to 250°C), it is significantly more expensive. This limits the use of plastic cages in jet engine hot sections or extreme industrial ovens.
Sensitivity to Oil Additives:
Certain aggressive additives in modern lubricants (especially EP additives used in gearboxes) can chemically attack polyamide cages over time, leading to embrittlement and failure. This necessitates rigorous material compatibility testing.
Raw Material Volatility:
The price of engineering plastics is linked to petrochemical feedstock prices. Fluctuations in oil prices or supply chain disruptions (as seen in the nylon shortage of the early 2020s) can squeeze margins for cage manufacturers.
Technological Trends and Future Outlook
Hybrid Lubrication Materials:
