Rod-End Misalignment and Clearance
Spacers position a rod end between mounting tabs while adding clearance around the spherical ball and fastener. Select the spacer width, bore, and shoulder geometry to preserve the required angular travel.

Overview
ROD END SPACERS SCNS / CNS Product Overview
SCNS8 / CNS8 is a 1/2″ bore cone spacer. OD (A) = 0.592″, cone depth (C) = 0.1″, outer flange OD (D) = 0.875″, flange width (E) = 0.375″. Cone angle: 28°.
SCNS (stainless steel) and CNS (zinc plated carbon steel) cone spacers are used with rod ends and spherical bearings to provide a tapered seating for pins or bolts passing through clevis-mounted assemblies. The conical face distributes load and allows slight angular misalignment between the pin and the bearing race. Used in steering, suspension, and linkage applications where clevis pins are employed.
Stainless: SCNS8. Carbon steel (zinc plated): CNS8. Standard flat spacers also available in the SCW/CW series. Sold individually; install in pairs for symmetrical assemblies.

FAQ
ROD END SPACERS SCNS / CNS Frequently Asked Questions
What is the SCNS8 / CNS8 cone spacer used for?
The SCNS8 / CNS8 is a 1/2" bore cone spacer used with rod ends and spherical bearings to provide a tapered seating for pins or bolts passing through clevis-mounted assemblies — the conical face distributes load and allows slight angular misalignment between the pin and the bearing race. It's used in steering, suspension, and linkage applications where clevis pins are employed.
What are the dimensions of the CNS8 cone spacer?
Bore (B) is 1/2", OD (A) is 0.592", cone depth (C) is 0.100", outer flange OD (D) is 0.875", and flange width (E) is 0.375". Cone angle is 28°.
What is the difference between SCNS8 and CNS8?
SCNS8 is the stainless steel version and CNS8 is the zinc-plated carbon steel version of the same 1/2" cone spacer — same dimensions and cone angle, different material for corrosion resistance versus cost.
How should the CNS8 cone spacer be installed?
The CNS8 is sold individually; install in pairs for symmetrical clevis-pin assemblies so the tapered faces seat evenly on both sides of the joint.
Is a flat (non-cone) spacer version available for the 1/2" bore size?
Yes. Standard flat spacers in the same 1/2" bore size are also available in the SCW/CW series, alongside this cone-style SCNS/CNS spacer.
What cone angle does the CNS8 use?
The CNS8 has a 28° cone angle, which is specific to this bore size in the SCNS/CNS lineup — confirm this angle matches your clevis and pin geometry before ordering.
