Professional Stainless Steel Rod End Manufacturer

stainless rod end kits

Profab Machine has manufactured stainless steel rod ends for OEM and industrial customers for more than 20 years. Every rod end is CNC machined in-house, in the grade and configuration your application requires.

Four series cover the main application requirements: loader-slot PTFE-lined (XM/XF), metal-to-metal two-piece (CM/CF), three-piece PTFE-lined (JMX/JFX), and three-piece greasable (SATK/SITK). Thread type, housing grade, and surface treatment are specified at order, not defaulted.

All dimensions, thread classes, and material grades are documented with full batch traceability. If your requirement falls outside the standard range, custom specifications are handled by the same manufacturing team.

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. Custom Grade like 2205 is available.

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

Molybdenum addition gives 316L roughly 3× better chloride resistance than 304. Required for marine applications, salt-spray environments, offshore, and food-grade lines with CIP chemical cleaning.

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 is a martensitic stainless with hardness up to HRC 58 after heat treatment. It is the industry standard for rod end balls because it combines adequate corrosion resistance with the hardness needed to withstand Hertzian contact stress in the socket. All Profab rod ends use 440C balls unless specifically requested otherwise.

Rod End Accessories

Build a Complete Rod End System

Build a complete rod end system with precision-machined accessories manufactured to the same quality standards as your rod ends. Every component below is available in matching 304 or 316L stainless. 

Pre-assembled combinations of rod end, jam nut, and selected accessories. You give us the linkage specification. We ship a ready-to-install kit. Every part in the kit shares the same material and batch traceability. No hunting for matching hardware from three different suppliers.

Clevis Joints For Rod Ends

The clevis provides a secure pin connection, while the rod end accommodates angular movement and minor misalignment.

High Misalignment Rod End

The ball gets more angular travel before the housing body hits the bracket. Custom thicknesses on request.

Studded Rod Ends

No separate bolt needed. This configuration shortens the overall linkage stack height.

Rod Ends With Jam Nuts

Thread class matches the rod end exactly. No galling from mismatched thread tolerances.

Rod Ends Bungs

Weld chamfer cut before threading. Thread chased after machining so it runs true to the bung axis. Your rod end screws straight in with no angular runout.

Rod End Linkage Adjuster

Hexagonal bar stock with opposing left-hand and right-hand threads at each end. Rotate the hex bar to extend or retract your linkage without disconnecting either end.

Turnbuckle Hex Bar

Standard on steering tie rods and adjustable control linkages. Custom lengths and thread combinations to your drawing.

Uniball Cups

A housing cup that retains a spherical bearing inside your control arm or linkage plate. The cup bore is precision-bored to press-fit the bearing with the correct interference.

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.

Built for Motion Control Applications Where Reliability Matters

In marine environments, stainless steel performs well against salt spray, humidity, and brackish water. It helps reduce rust, pitting, and seizure in steering linkages, actuators, and other exposed moving parts. Because corrosion resistance is built into the material itself, the protection is not limited to a surface coating that can wear away over time.

In food processing equipment, stainless steel is a strong fit for frequent washdowns, steam cleaning, and chemical sanitation. It helps minimize surface damage where contamination can start and supports cleaner operation in hygiene-sensitive areas. For equipment that must stay dependable under repeated cleaning, stainless steel rod ends offer a more practical long-term solution.
