Use caseMedium precision round-trip conveying applicationMedium-precision reciprocating conveying
Notes on useGenerally used in reciprocating and conveyance mechanisms that do not have high requirements on positioning accuracy.Generally used in mechanisms that frequently rotate forwardly and reversely and have requirements on positioning accuracy and backlash.

■Easier on-site assembly
·MISUMI Economy series timing pulley is chamfered at the shaft hole and tapped hole for easy installation, reducing assembly time by 27% compared to the timing pulley not chamfered

■Longer service life of timing belt
·Misumi's economical timing pulley has been deburred at the threaded hole, which is not easy to wear the timing belt. It is cheap and can also increase the service life of the timing belt.

Example of Use
Use Misumi timing pulley to design the workpiece reversal transfer mechanism example
Mechanism name
Workpiece reversal transfer mechanism

Mechanism function
Rotate the workpiece on the conveyor belt 90 degrees and transfer it to the next process.
At this time, the clamping mechanism rotates 180 degrees, and the workpiece direction is not changed relative to the conveying direction during transfer.

Function of timing pulleys
Through the transmission of timing pulleys and timing belts, the workpiece placement direction can be changed while transferring the workpiece. (Applicable to S specification and GT specification timing pulleys)
