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

Usage Method Example Drawing

Usage Method of Timing Belt Backside Tensioning Idlers

When the backside tensioning idler is used on the outside, the selected pulley diameter should be more than 20% larger than the minimum pulley diameter in the product catalog.
① When the backside tensioning ilder is used on the outside, it should be set close to the large pulley.
② The bending angle of the machine belt should be greater than 140#.
③ The flat pulley without bulge should be used for the tensioning idler.
④ Do not use the backside tensioning idler for the polyurethane belt.

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.
