Usage Method

Example of Use
Recommended Applications	Flat Belt Roller Conveyor Mechanism The rollers are connected to drive the flat belt, enabling the transportation of objects.	Timing Pulley Drive Mechanism Connects the driven shaft to the timing pulley to achieve reverse transmission.	Bearing and Coupling Rotating Structure By connecting bearings and couplings, same-direction transmission is achieved.

MISUMI Misumi Shaft - Complete Selection of Straight Rod Type with Keyway

Equipment Name: Embedded Fixture
Function Description:
An insert assembly jig for embedding into rubber and aluminum workpieces, allowing the protruding part of the rubber to be inserted into the recessed part of another workpiece. The load can be adjusted using bolts and tightened with the roller.

The Role of the Shaft in Mechanisms
(1) The shaft is used as a fastening connector in mechanisms, bearing the pressure applied by the spring and connecting the roller to press the workpiece.
(2) Excellent roundness and straightness ensure even force distribution during use of assembly jigs, enhancing the overall stability of the fixture.
