R-Joint Rod End Spec Sheet

Welcome to the R-Joint Rod End Spec Sheet! The following R-Joint and R-Joint XL rod end specifications and degrees of articulation helps implement R-Joint rod ends in engineering projects. For custom sizing, click HERE to contact us. Armed with the R-joint spec sheet below, you’ll be all set to head on over to the R-Joint Product page and shop for the appropriate R-Joints for your project. 

R-Joint XL Dimensions and Articulation:

Thread Sizes: 1.25-12 RH/ 1.25-12 LH and 1.00-14 RH/ 1.00-14 LH
Through Bolt Size: 0.562” – 9/16” [other sizes available, see table below]
Total Articulation: 50 deg [will vary by through bolt size, see table below]

R-Joint XL Material Specs:

  • Ball: 304 Stainless Steel
  • Composite: RTX10
  • Wave Spring: 17-7 Stainless Steel
  • Retainer Ring: 302 Stainless Steel
  • Housing: 17-4 Stainless Steel
  • Spacers: 303 Stainless Steel
  • Housing Manufacturing:

R-Joint XL housing is investment cast in the United States. The Casting then goes through a H900 Solution Anneal heat treatment to remove any crystallization. The heat treatment both increases tensile strength and ductility. All threading and machining is performed post heat treatment.
Composite Yield [starts to deform]: 17,250lbs
Composite Failure: 17,750lbs
Housing Yield [starts to deform]: 95,000lbs
Housing Failure: 1.00 Thread: 109,850lbs
1.25 Thread: 121,765lbs
