Example of Use

Example drawing of a belt tensioning device designed using MISUMI timing idler pulley

■Organization Name
Belt Tensioner (Manual)

■ Mechanism Function
1. Moves the roller on the adjustment side to tighten and secure it while the conveyor belt is open.
2. When using multiple drives, increase the engagement rate by setting the roller to the center position.

■ Function of the Timing Belt Idler

1.	Fix the belt assembly distance with a timing belt idler
	At the same time, the polyurethane roller assists in tensioning the belt
