Product Overview

Usually, timing pulleys, timing idlers and timing belts are widely used to design mechanisms for transmitting rotational power generated by motors.
Driving and transmission are realized through the engagement between the teeth of timing pulleys, timing idlers and timing belts.

Dimensional Drawing

Bearing is pressed fit.

Bearing accuracy JIS B1514 Class 0 / GB T 307-94 P0 (before press-fitting).

MISUMI does not guarantee the bearing brand.

(2) Starting from 2014, flanges of S14M specification are not riveted and will be shipped separately together with the order.

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
