Misalignment Angles

Misalignment

  • a = Angle of Misalignment
  • B = Bore of Ball
  • D = Head Diameter (Rod End)
  • E = Ball Spherical Diameter
  • S = Shoulder Diameter (Neck Ball)
  • T = Housing (Race) Width
  • W = Width of Ball
The misalignment angle of a rod end or spherical bearing refers to the angle between the ball centerline and the outer member centerline when the ball is misaligned to the extreme position allowed by the clevis or shaft design, as applicable. Figures 1 - 4 illustrate bearing misalignment and a formula for calculating each.
