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 SPACER SG / HMS Product Overview
SG16-1012 / HMS16-1012 is a high-misalignment spacer with 0.999″ bore (D), 1.250″ housing OD (D2), spacer width (B) = 0.625″, outer flange width (W) = 0.750″, inner flange width (W2) = 0.673″. Misalignment angle: ±60°. Total installed width: 2.875″.
SG (stainless steel) and HMS (carbon steel, zinc plated) high-misalignment spacers are used with rod ends and spherical bearings to increase angular articulation range beyond the standard body-to-housing clearance. A pair of spacers allows the rod end to misalign further without the housing contacting the mounting bracket — suited to suspension links, steering arms, and other assemblies where high angular travel is required.
Stainless version: SG16-1012. Carbon steel: HMS16-1012. Used in pairs (one each side of the rod end or bearing). Compatible with COM series spherical bearings and standard rod ends with matching bore.

FAQ
ROD END SPACER SG / HMS Frequently Asked Questions
What is the SG16-1012/HMS16-1012 rod end spacer used for?
It's a high-misalignment spacer with a 0.999" bore (D) used with rod ends and spherical bearings to increase angular articulation range beyond the standard body-to-housing clearance. Fitted as a pair (one on each side of the rod end or bearing), it lets the rod end misalign further without the housing contacting the mounting bracket — suited to suspension links, steering arms, and other assemblies where high angular travel is required.
What is the difference between the SG16-1012 and HMS16-1012 versions of this spacer?
SG16-1012 is the stainless steel version and HMS16-1012 is the zinc-plated carbon steel version of the same spacer — same dimensions, different material for corrosion resistance versus standard cost.
What are the bore and housing OD of the HMS16-1012/SG16-1012?
Bore (D) is 0.999" and housing OD (D2) is 1.250", with a spacer width (B) of 0.625" — confirm these against your rod end or spherical bearing's housing bore before ordering.
What misalignment angle does the HMS16-1012/SG16-1012 support?
This spacer is rated for approximately ±60° of angular misalignment, with a total installed width of 2.875" when the pair is fitted.
What do the outer and inner flange widths mean for the HMS16-1012/SG16-1012?
Outer flange width (W) is 0.750" and inner flange width (W2) is 0.673" — these control how the spacer seats against the mounting bracket face and the rod-end/bearing body, so check orientation when installing the pair.
What is the HMS16-1012/SG16-1012 compatible with?
It's compatible with COM series spherical bearings and standard rod ends with a matching bore, and is used in pairs — one spacer fitted on each side of the rod end or bearing.
