    Precautions
    ①For Shaft Bore Specs. P (round hole+threaded hole) or N, the attached set screws are shipped in the same package (may drop in the packaging bag).
    ②There is no threaded hole for Shaft Bore Specs. H (round hole).
    ③There may be no surface treatment in the shaft bore.
    ④For the N keyway hole, the position relation between keyway and tooth is not fixed.
    Example of Use
    Example drawing of a workpiece reversal transfer mechanism designed using MISUMI timing pulley timing pulley
    Example Name:
      Workpiece Reversal Transfer Mechanism
    Purpose:
      Rotates the workpiece on the conveyor belt by 90 degrees and transfers it to the next process, using the transmission power of the timing pulley and the timing belt.
      At this time, the clamping mechanism rotates 180 degrees and does not change the direction of the workpiece relative to the conveying direction at the same time during transfer.
    Purpose of Timing Pulley:
      The transmission of the timing pulley and the timing belt changes the placement direction of the workpiece while transferring the workpiece. (Applicable to S specification and GT specification timing pulleys)
