Material Specification
Choosing the Right Grade
The housing material is what you’re really specifying when you order. The ball is always 440C. Below is a quick reference — wrong grade is the most common reason rod ends fail prematurely in corrosive environments.
304 Stainless
General-purpose grade. Good resistance to humidity, mild chemicals, and food-safe cleaning agents. Use this for indoor machinery, agricultural equipment, and dry-run automation.
Food · Automation · Indoor
316 / 316L
The molybdenum content of 316L provides better resistance to chloride-induced pitting and crevice corrosion than 304 stainless steel. Often preferred for marine, salt-spray and chloride-rich environments where improved pitting and crevice corrosion resistance is required.
Marine · Chemical · Pumps
17-4PH
Precipitation-hardened grade. After H900 heat treatment, tensile strength reaches ~1310 MPa — significantly stronger than 316. Used in motorsport, aerospace, and high-cycle fatigue applications where load ratings matter more than cost.
Aerospace · Motorsport · Hi-load
440C Stainless Ball — Standard on All Series
440C balls are used as the standard bearing material where hardness and wear resistance are the primary requirements. For highly corrosive or marine applications, alternative ball materials or surface treatments can be specified according to the operating environment.

Why Material Selection Matters in Rod End Performance
Unlike many mechanical components, rod ends combine moving contact surfaces, exposed threads, and constant articulation within a single assembly. This makes them especially vulnerable to corrosion, contamination, and surface wear over time. In many cases, rod end failures begin not with overload, but with environmental damage that increases friction, restricts movement, and accelerates bearing wear.
Stainless steel addresses these issues at the material level rather than relying on plated or coated surfaces for protection. The naturally formed passive layer on 304 and 316 stainless steel helps resist rust, moisture intrusion, and chemical attack even when the component experiences repeated movement or minor surface abrasion. As a result, stainless steel rod ends often maintain smoother articulation, lower maintenance requirements, and longer service intervals in demanding operating environments.

FAQ
Common Questions
Not seeing your question? Email us at [email protected] and we typically reply same day.
What stainless steel grades do you offer? Can you provide Material Test Certificate (MTC)?
We routinely provide 304, 316, 316L, and other grades. We can provide Material Test Certificate (MTC) and proof of chemical composition upon request.
How to choose the right rod ends according to the load and working condition?
Please provide the maximum static/dynamic load, mounting geometry (swing angle), shaft diameter and frequency of use. We will recommend a model or give calibration suggestions based on the load table and fatigue data.
Are there low maintenance versions with self-lubricating or polymer bushings?
Yes. For applications requiring low friction or low maintenance, we offer variants with polymer bushings or self-lubricating liners to reduce the frequency of lubrication maintenance.

Rod End Knowledge Base
Food Grade vs. Washdown Rated Rod Ends
A rod end listed as food grade may only mean the lubricant is NSF H1 certified. One listed as washdown rated may only mean it passed an IP65 spray test. Neither label tells the full story. Here’s how to read the specs correctly.
Industrial vs Aerospace Rod Ends: Key Differences and When to Use Each
The difference between an industrial rod end and an aerospace-grade rod end isn’t just price. It’s tolerance stack-up, liner construction, traceability documentation, and which failure mode is acceptable. Here’s how to tell which one your application actually needs.
How Are Rod Ends Measured?
Thread size alone does not define a rod end. Bore diameter, body width, housing OD, shank length, and misalignment angle all matter. Here is how to measure each one and what to do with the numbers.
