Angular misalignment. •Offset or Parallel Misalignment is measured in thousandths of an inch (0.000”), also called mils. Step 1: You need to follow Solution 2 to print the top check at the right position first. 2. Misalignment can occur in three ways: Radial (offset or parallel) misalignment The centrelines of the two shafts are parallel but offset. Misalignment shaft couplings are necessary to compensate for the subtle and sometimes extreme angular, radial and axial misalignment between mating shafts. Cursor Misalignment in Excel I continually encounter cursor misalignment using Excel for Mac 2016. If the motor shaft is under an angle with the shafts in vertical position, then it called an angular vertical misalignment.
