Technical Tips For Measuring Shaft Collars and Couplings

How to Measure Shaft Collars and Couplings

Selecting the correct shaft collars requires understanding product specifications and how the part you are buying will be used.  

Important specifications to review when selecting collars include:

  • Thread types 
  • Width
  • Bore diameter
  • Outer diameter
  • Axial load capacity

Measured in pounds (lbs) or kilograms (kg), axial load capacity is the maximum load that can be applied along or parallel to and concentric with the primary axis. Source: According to Engineering360 

 

Improper selection of couplings can lead to premature failure, and excessive wear, cause failure in expensive components like bearings, shafts, and gears, and most importantly can result in costly downtime.

Important specifications to review when selecting couplings include:

  • Application Requirements and Variables (torque, stiffness, etc.)
  • Addressing shaft misalignment concerns
  • Operating environment
