Custom CNC Rod End Bearings - Trusted China Supplier & Manufacturer Factory for Quality Products
High-altitude flight exposes materials to extreme pressure and temperature fluctuations. Our high-strength aluminum alloys are more than capable of meeting these demands. From the thin fuselage skin that insulates against cold and maintains cabin pressure, to internal components like seats, aluminum's lightweight nature helps aircraft save fuel, cut emissions, and carry more payload. FRIMA's precision machining ensures every aerospace component is flawlessly executed.
Aluminum can be drawn into fine wires for everyday items such as light bulb filaments and telephone lines. Long-distance, high-voltage overhead power lines also largely rely on aluminum conductors, which strike the ideal balance between conductivity and weight. Our machined aluminum terminals and connectors guarantee stable, reliable power transmission.
In the event of a car crash, aluminum structures are capable of absorbing a major portion of the impact energy. Our body structural components and crash energy-absorbing boxes offer passengers an extra layer of protection. Lightweight does not mean unsafe – aluminum proves this point convincingly.
Thanks to its low weight, high strength, and excellent formability, aluminum is an ideal material for modern transportation. Our machined aluminum CNC milling parts are widely used in automotive, aerospace, rail, and marine applications – especially in engine components, helping to reduce fuel consumption and emissions. A lighter vehicle body requires less energy, a goal pursued by the global transportation industry.
Aluminum's natural resistance to corrosion and low maintenance needs make it a great choice for both new builds and renovation projects. Its high strength combined with low weight allows us to enhance building safety effectively in earthquake-prone areas using our aluminum components. In addition, aluminum's excellent light reflectivity makes it a common material in lighting fixtures.

aluminum application
-
1What specifications can I customize for a rod end bearing?You can customize the bore diameter, thread size and direction (left/right hand), housing material (steel, stainless steel, aluminum), ball material (chrome steel, 440C stainless), coating (zinc plating, anodizing, PTFE), and lubrication type (grease fitting or self-lubricating liner).
-
2How do I provide my design requirements?You can submit a 2D drawing (PDF or DXF), a 3D CAD model (STEP or IGES), or simply fill out our specification sheet with thread size, load range, and environmental conditions. Our engineers will also help optimize the design for manufacturability.
-
3What is the typical lead time for a custom made CNC rod end bearing?Prototype quantities (1–10 pieces) usually take 1–2 weeks. Production batches (100–1000 pieces) typically require 3–5 weeks, depending on complexity and material availability.
-
4Are these bearings suitable for high-temperature or corrosive environments?Yes. For high temperatures (up to 300°C), we offer alloy steel with heat-stabilized lubricants. For corrosive environments, choose stainless steel housings with a passivated ball and a PTFE liner.
-
5Do you offer both male and female thread configurations?Absolutely. We can produce rod end bearings in male thread (stud type) or female thread (housing type), with or without a mounting slot or wrench flats, as per your drawing.
-
6What quality control measures are in place for custom CNC rod end bearings?Every bearing undergoes dimensional inspection using CMM (Coordinate Measuring Machine), surface roughness testing, load and torque verification, and visual inspection prior to shipment. We provide full inspection reports and traceability documentation upon request.
