Building to FAA PMA Specifications: How to Source Replacement Rod Ends and Bearings with Confidence
What FAA PMA is, and what it is not If you work in aerospace sustainment, you have seen PMA referenced in RFQs, supplier qualification checklists, and approvals packages. The FAA defines Parts Manufacturer Approval (PMA) as a combined design and production approval for modification and replacement articles, allowing a manufacturer to produce and sell those […]
High-Temperature Rod Ends and Linkages for Heat, Vibration, and Harsh Environments
Heat turns “good enough” linkage designs into failures fast. If you have ever chased a hot-zone problem in an engine bay, exhaust-adjacent system, or high-temp actuation path, you have seen the same pattern: materials and friction behavior that look fine at room temperature become unpredictable at elevated temperatures. Add vibration, contamination, and long cycle life, […]
Load and Misalignment Basics for Rod Ends and Spherical Bearings
Most bearing issues do not start with a “bad part.” They start with a spec that did not match the real load path, motion, or misalignment inside the assembly. This matters most in motion control systems where the joint is doing real work: control surfaces, landing gear and struts, steering linkages, actuators, turbines and jet […]
Certified Quality Systems and Domestic Manufacturing Reduce Supply Chain Risk
In aerospace and defense, supply chain risk is not just a procurement issue. It is a product quality issue, a delivery issue, and in many cases, a safety issue. When critical linkage components are delayed, undocumented, or inconsistently produced, the impact can ripple across schedules, assembly flow, compliance requirements, and field performance. That is why […]
Rod Ends and Spherical Bearings for Mission-Critical Systems
In aerospace and defense, linkage components do not get treated as commodity hardware. They are specified for control, reliability, and long-term performance in systems where side load, vibration, contamination, cycle fatigue, and misalignment can quickly expose the wrong design choice. That is why selecting the right aerospace rod ends and spherical bearings starts with a […]
