Additional Description

Curtis double joints are available in 14 sizes, and share all of the advantages of Curtis single U-joints. Features include:

  • Bored Hubs are bored one-half of the O.D.
  • Material is alloy steel
  • Extra angularity allows standard units to operate at angles up to 70°.
  • Quick and easy TakeApart design for easy and economical disassembly and reassembly, with no special tooling required.
  • Firm, positive lockup of the entire assembly thanks to Curtis’ exclusive Tell-Tale Lock Ring.
  • Built-in lubrication passages with Curtis’ exclusive internal lubrication system.
  • Lubrication covers (boots) available in all sizes to retain lubrication and keep out contaminants, extending the life of the joint. Curtis Joints do not require grooves on hubs to retain boots.
  • Less galling and seizing because Curtis uses dissimilar materials on all bearing surfaces.
  • Maximum wear and strength from Curtis’ induction hardened forks.
  • Easy machinability due to Curtis’ soft hubs.
  • Smooth operations and longer life assured by close and well-controlled tolerances between mating parts and Curtis’ built-in lubrication system.
  • Perfect concentricity with hubs ground on center and centering holes provided on solid hubs to aid in machining.

Universal joint hub modifications are available per customer specifications, which include but may not be limited to bores, keyways, set screw holes, square holes and hex holes. Contact the Curtis sales department for more information.
