For Sleeve Bearing Motors And All Other Applications Requiring Axial End-Float Restrictions (Meets API 610 Standards Maximum Coupling End Float Requirements) Use limited end float hubs and inserts for applications with sleeve bearing motors, ID & FD fans or any application requiring limited axial end float. All other components are standard; they can be used in non-spacer, flywheel, etc. Note: Limited end float couplings can be special ordered for end float +/- increase or decrease and accommodate greater angular misalignment.
