HTD timing belt idlers, suitable for MISUMI Economy series HTD Timing Belts.Example of Timing Pulley Use
■Timing Pulley 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
1. The belt is tensioned by fixing the belt assembly distance with the timing belt idler
and with the assistance of the urethane roller.
For more information, please click Example for Belt Tension Device.

Frequently asked question (FAQ)
- Question: Why does the flange drop during the use of a timing belt idler?
- Answer: 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.
- Question: Is it possible that no flange is attached to the timing belt idler product?
- Answer: Yes. Generally, the timing belt idler is shipped with flange attached. If the customer selects NFC (flange not attached) and RFC·LFC (flange attached on one side only) of MISUMI alteration specifications, no flange will be attached.
- Question: Why is the color of MISUMI's clear anodized timing belt idler similar with the hard anodized one?
- Answer: 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.
- Question: What is the idler?
- Answer: It mainly plays the role of tension adjustment and auxiliary transmission of the timing belt.
- Question: What does the number in the timing belt idlers S2M, S3M, P2M, P3M, T5, T10, 2GT, 3GT, etc. mean?
- Answer: 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.
