SCM-T / SCF-T Rod Ends
Stainless · InchCorrosion-resistant 304 stainless body with a hardened 440C stainless ball and a PTFE liner for maintenance-free operation. Cross-ref FK, QA1.
Corrosion-Resistant Stainless + Specialty-Liner & High-Misalignment Rod Ends
Stainless, High-Misalignment
& Self-Lubricating Rod Ends
Specialty rod ends solve one of three problems standard steel rod ends cannot: corrosion, extra articulation angle, or zero-maintenance running. Choose 304 stainless with a 440C ball for marine and washdown service, PCM/PCYM high-misalignment chromoly for wide articulation, or bronze, nylon and copper-PTFE races for self-lubricating industrial links.

Overview
How the Range Breaks Down
The range splits into three practical groups, so you can choose by the real requirement first: corrosion resistance, extra misalignment, or low-maintenance specialty race design.
If you need a fixed stud-style attachment instead of a rod end body, see the dedicated Rod End
Studs page.
Stainless Steel (SCM / SCF)
Corrosion resistance is the dominant
requirement. Standard 304 body, 440C ball, and self-lubricating PTFE liners.
High-Misalignment (PCM / PCYM)
Wide articulation angle is the
requirement; these are built from high-strength 4130 chromoly (not stainless).
Specialty Self-Lubricating Races
Low maintenance at moderate load
without paying for stainless. Features sintered bronze and molded nylon race designs.

Choosing the Right Series
Which Specialty Family Fits the Job?
Start with the dominant requirement, then confirm exact bore, thread, angle and load on the spec page.
Corrosion → SCM
Choose SCM-T/SCF-T for inch or SCM-MT/SCF-MT for metric. Both use 304 stainless bodies, 440C balls and PTFE liners.
Articulation → PCM / PCYM
PCM is the confirmed inch high-misalignment option. Current PCYM product records are inch UNF even though the taxonomy label says Metric; verify before ordering.
Low maintenance → specialty races
VM/VF use sintered bronze; PM/PF and MPM/MPF use molded nylon; SA-TK/SI-TK use a copper-alloy PTFE race.
Exact part selection: verify bore, thread, misalignment angle, liner/race and load on the individual series page. For a threaded stud rather than a bearing-style rod end, use Rod End Studs →.
Applications
Where Specialty & Stainless Rod Ends Perform
Match the environment first, then confirm the series-specific load and clearance.
Marine & outdoor
SCM/SCF when salt spray, moisture and rust staining are the dominant risks.
Food & washdown
304/440C stainless with PTFE lining for washdown areas where grease access is limited.
Corrosion evidence
Use salt-spray and material-certificate review to select stainless instead of a plated steel body.
| Application | Series | Why |
|---|---|---|
| Marine steering / deck hardware | SCM/SCF | 304 body + 440C ball + PTFE through the bearing assembly |
| Food / pharma / washdown | SCM-T/SCF-T | Stainless construction with no routine grease requirement |
| Chemical plant linkages | SCM-MT/SCF-MT | Metric stainless option; confirm chemical compatibility |
| Off-road long-travel suspension | PCM(-T) / PCYM family | High articulation; verify PCYM unit designation before order |
| Custom 4-link / high articulation | PCM(-T) | Wide angle without binding |
| Test and measurement equipment | PM/PF, MPM/MPF | Molded nylon for low friction, damping and low clearance |
| Low-maintenance industrial links | VM/VF, SA-TK/SI-TK | Self-lubricating bronze or copper-PTFE race |

FAQ
Common Questions
What grade of stainless are SYZ stainless rod ends?
A 304 stainless body with a 440C stainless ball and PTFE liner — corrosion
resistance plus self-lubrication. SCM-T/SCF-T (inch) and SCM-MT/SCF-MT (metric).
When are stainless rod ends worth the premium over zinc-plated steel?
When the joint faces continuous moisture, salt spray, chemical exposure or
washdown — zinc plating delays but doesn’t prevent corrosion and can wear through. Stainless resists
corrosion through its full cross-section.
Are stainless rod ends as strong as steel?
Stainless trades some load margin for corrosion resistance. For maximum
strength in a non-corrosive setting, chromoly is stronger; choose stainless when the environment would
corrode plated steel.
What is a high-misalignment rod end and which series?
One built for a wider angular range before binding — PCM(-T) (inch) and
PCYM-T/PCYF-T (current product records: inch; taxonomy label says Metric — verify), 4130 chromoly with black oxide and PTFE.
What does “self-lubricating” mean across these series?
A race that needs no grease: PTFE liner (stainless, PCM), sintered bronze
oil-impregnated (VM/VF), molded nylon (PM/PF, MPM/MPF), or copper-alloy PTFE (SA-TK).
Molded nylon race vs PTFE liner — which lasts longer?
A molded nylon race is a thick structural component (longer wear life,
vibration damping, zero clearance) but lower max load; a PTFE liner is a thin low-friction layer that can
wear through but supports higher loads on a metal race. Choose by load vs precision needs.
Do you offer a studded rod end?
Yes — source studded or threaded-stud parts separately from the Rod End Studs page. This page covers bearing-style stainless and specialty-liner rod ends.
Are they available in inch and metric?
Yes — inch (SCM-T, PCM, VM, PM) and metric (SCM-MT, MPM, SA-TK); current PCYM product records are inch and should be verified before ordering.
What grade of stainless are SYZ stainless rod ends?
A 304 stainless body with a 440C stainless ball and PTFE liner, giving corrosion resistance plus self-lubrication. SCM-T/SCF-T are inch and SCM-MT/SCF-MT are metric.
When are stainless rod ends worth the premium over zinc-plated steel?
When the joint faces continuous moisture, salt spray, chemical exposure or washdown. Zinc plating delays but does not prevent corrosion and can wear through; stainless resists corrosion through its full cross-section.
Are stainless rod ends as strong as steel?

One built for a wider angular range before binding — PCM(-T) inch and PCYM-T/PCYF-T (current product records: inch; taxonomy label says Metric — verify), 4130 chromoly with black oxide and PTFE.
What does self-lubricating mean across these series?
A race that needs no grease: PTFE liner (stainless, PCM), sintered bronze oil-impregnated (VM/VF), molded nylon (PM/PF, MPM/MPF), or copper alloy with PTFE (SA-TK).
Molded nylon race versus PTFE liner — which lasts longer?
A molded nylon race is a thick structural component with longer wear life, vibration damping and zero clearance but lower max load; a PTFE liner is a thin low-friction layer that can wear through but supports higher loads on a metal race.
Do you have a studded rod end?
Yes. Source studded or threaded-stud parts separately from the Rod End Studs page; this page covers bearing-style stainless and specialty-liner rod ends.
Are stainless and specialty rod ends available in inch and metric?
Yes. Inch options include SCM-T, PCM, VM and PM; metric options include SCM-MT, MPM and SA-TK; current PCYM product records are inch and should be verified before ordering.
