Why does the flange drop during use of a timing belt idlers?

The function of the flange is to prevent production accidents caused by deviation and drop of the timing belt. Therefore, the flange drops mainly because it is squeezed off by the timing belt that has deviated for a long time. We recommend that the customer regularly check the condition of the timing belt of the equipment to avoid its deviation.

Why is the color of MISUMI's clear anodized timing belt idler similar with the hard anodized one?

As the clear anodized and hard anodized coating of MISUMI's timing belt idler is relatively thin (about 2 microns), it is difficult to distinguish the color.

It mainly plays the role of tension adjustment and auxiliary transmission of the timing belt.

What does the number in the timing belt idlers S2M, S3M, T5, T10, etc. mean?

It mainly represents the tooth pitch of the belt, that is, the distance between two adjacent teeth. They are also the tooth profile models in the timing belt industry.

Usage Method Example Drawing	Instructions for Use of Timing Belt Idlers and Timing Belt
	③Conveyance Plates are conveyed by two timing toothed belts
	④Traction transmission Workpieces are clamped and transmitted by the belt

Shape S timing pulleys, suitable for MISUMI Standard Shape S Timing Belts and Economy Series Shape S Timing Belts.

Example of Use

■ Mechanism name
Belt tension device (manual)

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

■ Role of the timing belt idler
The belt is tensioned by fixing the belt assembly distance with the timing belt idler
and with the assistance of the urethane roller.
