CLEVIS CR / CL Series
InchInch rod-end clevises manufactured from carbon steel with zinc plating. Available in CR (right-hand thread) and CL (left-hand thread) configurations for turns-adjustable linkage systems.
Single-Axis Pin Joints for Linkage & Cylinders
Clevis & Yoke Ends
A clevis (yoke end) is a U-shaped fitting with a cross pin that gives a single-axis pivot — used where a linkage hinges on one plane rather than articulating spherically like a rod end. SYZ offers carbon steel zinc-plated clevises in inch (CR right-hand / CL left-hand) and metric (G-series, DIN 71751 compatible), threading onto rods, cylinders and adjusters.

Product Guide
What Are Clevis & Yoke Ends?
A clevis (yoke) end is a forked fitting joined by a clevis pin, providing rotation on one axis — ideal for hydraulic/pneumatic cylinder rods, brake/throttle linkage and machinery where the motion is planar.
Unlike a rod end (spherical, multi-axis), a clevis is simpler and constrains motion strictly to the pin axis. SYZ clevises thread onto rods and adjusters with RH or LH thread (inch) or metric thread standards.
Motion Constraint: A clevis is the simplest and often the most rigid of the three joint styles because it constrains joint movement strictly to one axis. Choose a clevis when cylinder rods, pedals, or linkages move in a single plane. Reach for a rod end only when the geometry tilts out of plane.

Choose Your Clevis Series
We supply carbon steel clevises in standard inch dimensions and metric European DIN specifications.
G CLEVIS Series
Metric G / DIN 71751Metric female fork-head (clevis) joints conforming to DIN 71751 machinery standards. Zinc plated carbon steel, ideal for drop-in cylinder rod extensions and European machinery.
Assembly & Sizing Checklist
- • Thread sizing: Match the thread size (and hand, RH/CR vs LH/CL) to your rod or cylinder shaft.
- • Bore diameter: Match the bore size directly to the clevis pin diameter you plan to run.
- • Jaw width: Ensure the fork gap width matches the thickness of your mating tab to avoid play or jamming.
- • Pin retention: Select cotter pins or retaining clips based on serviceability needs.
Comparison
Joint Selection Guide
Choose the correct technology based on your system articulation requirements.
| Joint Style | Motion Profile | Mounting Style | Best Applications |
|---|---|---|---|
| Clevis / Yoke End | Single-axis hinge (one plane) | Cross pin passing through U-fork | Linear cylinder rods, brake pedals, planar automation linkage |
| Rod End (Heim Joint) | Multi-axis spherical articulation | Bolt passing through spherical ball bore | Suspension arms, steering linkage, components with misalignment |
| Ball Joint | Multi-axis compact angular articulation | Threaded ball-stud inside a socket housing | Throttle controls, light shifter links, quick-disconnect assemblies |
Applications
Where Clevises Perform
Industrial-grade single-plane linkage pivots trusted globally.
Cylinders & Actuators
Cylinder rod extension linkages for pneumatic and hydraulic cylinders. Constrains rod travel to a single straight path.
Control Pedal Linkage
Standard fork connections for brake and throttle pedal rods in custom automotive, agricultural, and industrial machinery.
Planar Machinery Hinge
Perfect for linkage bars in food processing, sorting conveyors, and agricultural equipment where parts move in fixed planes.
FAQ
Common Questions
What’s the difference between a clevis and a rod end?
A clevis pivots on a single pin axis (planar motion); a rod end uses a spherical bearing for multi-axis articulation. Use a clevis when the joint hinges in one plane.
What is DIN 71751?
A standard for fork-head (clevis) joints common in European machinery; SYZ G-series clevises are DIN 71751 compatible.
What does CR vs CL mean?
CR is the right-hand thread clevis, CL is the left-hand — used together for adjustable linkages where turning the rod changes length.
What’s a yoke end?
Another name for a clevis — a U-shaped (forked) end joined by a cross pin.
How do I size a clevis?
Match the thread to the rod, the bore to the clevis pin, and the jaw width to the mating tab. Sizes are on the spec pages.
