Product Description

Product Overview

As a mechanism for transmitting the rotational power generated by the motor, timing pulleys, timing belt idlers and timing belts are usually widely used in design.
The transmission and transmission functions are achieved through the engagement between the timing belt pulley, the timing belt idler wheel and the timing belt teeth.

Product Features

■Tooth Profile Engagement of MISUMI Economy series Idlers
・The tooth profile of MISUMI's Economy idler gear complies with JIS and ISO standards, and it rotates more smoothly when matched with the standard belt tooth profile.

Example of Use

■Mechanism name
Belt Tension Device (Manual)

■Mechanism function
1. Move the roller on the adjustment side and tighten it while the conveyor belt is open.
2. For multiple driving applications, the engagement rate can be improved by setting the roller in the middle position.

■Function of the Timing Belt Idler
1. Fix the belt assembly distance with a timing belt idler
At the same time, the auxiliary polyurethane roller tensions the belt.
