ROD EYE Product Overview
RER12 / REL12 is a carbon steel rod eye with 3/4 bore × 3/4 thread. Pin bore housing OD (D) = 1.75″, ring width (W) = 0.875″, pin bore diameter (B) = 0.75″. Total length (A) = 2.875″, thread length (C) = 1.75″. Thread: 3/4-16.
The RER/REL rod eye is a closed-ring end fitting that accepts a pin or bolt through the eye bore. Used in applications where a clevis fork is not required and a solid ring-end pivot is preferred — such as cylinder rod ends, cable-to-rod connections, and simple pivot joints. Carbon steel body with zinc plating. Chromoly option available for higher strength applications.
Right-hand (RER12) and left-hand (REL12) thread configurations available. Heat-treated chromoly available on request. Clevis-fork equivalent: CR/CL series. Rod end (spherical bearing in head): XM/XF or JM/JF series.

ROD EYE Frequently Asked Questions
What is a rod eye used for?
A rod eye is used as an eye-end connection in linkage and hardware assemblies where a threaded mount and compact eye geometry are required.
What material is standard for this rod eye series?
The standard material is carbon steel with zinc plating, while chromoly steel is available as an option.
How do I compare rod eye fitment?
Start with bore x thread and B, then confirm D, W, A, C, and the thread reference against your assembly dimensions.
Are left-hand versions available?
Yes. The series includes left-hand threaded variants as shown by the paired part number structure.
Can rod eyes be used in heavy-duty linkage assemblies?
Yes. This style is commonly used in linkage and suspension hardware packages where a stronger eye-end connection is needed.
Can SYZ support custom rod eye requirements?
Yes. SYZ can review custom material, dimensional, and application requirements for OEM hardware programs.
