Avanced Self-Lubricating Liner Solutions 

NHBB is a leader in the development of self-lubricating liner solutions for demanding aerospace applications, such as engine mounts, landing gear gland assemblies, helicopter pitch-link control systems, and more. The many woven PTFE fabrics and machineable compounds we've developed contain specific properties that address any number of operating conditions and performance objectives. Wide-ranging solutions provide improved wear resistance for increased bearing life, machineability for precise fit and function, superior corrosion and moisture resistance for consistent performance in harsh conditions, high-temperature resistance for durable performance in the hot zone of jet engines, and more.
