Why does the flange drop during use of a timing pulley?

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 does the timing pulley has no threaded hole?

If you have requirements for fixing screws, we recommend that you choose a timing pulley with the shaft hole specification P (round hole + threaded hole) or N·C (keyway hole + threaded hole).

What should be done if there is jitter during use of a timing belt?

Readjust the tension of the timing pulley. Generally, the belt runs unstably due to excessive shaft spacing and insufficient tension.

Why cannot be the threaded hole of a MISUMI aluminum timing pulley locked tightly?

As the aluminum material is relatively soft, slippage may occur if the tightening force is too large during locking. We recommend that the customer stops tightening once an obstruction is felt.

How to fix a timing pulley when the shaft hole specification is H (round hole)?

Generally, H (round hole) can be used only after additional processing. If you need a product that can be directly fixed and used, please choose MISUMI P (round hole + threaded hole) or N (keyway hole + threaded hole) specifications.

What does the number in the timing pulley S2M, S3M, P2M, P3M, T5, T10, 2GT, 3GT, 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.

How to choose a timing belt after selecting a timing pulley?

First, the series must be matched. For example, the timing belts of S2M, S3M, and S5M can only match the timing pulleys of S2M, S3M, and S5M. Then, select the timing belt with an width corresponding to the ones indicated in the timing pulley specifications. Finally, select the needed perimeter.

Product Features

■Usage difference between economy series timing pulleys and MISUMI standard product / Example of customer use

	Economy series Timing Pulleys	MISUMI Existing Products
Example of Use
Precautions	Generally used in reciprocating and conveyance mechanisms that require medium positioning accuracy	Generally used in mechanisms that frequently rotate forwardly and reversely and have requirements on positioning accuracy and backlash.
Repetitive positioning accuracy (reference value)	Medium precision (±0.1)	High precision (±0.05)

■More Convenient On-site Assembly
·MISUMI Economy series timing pulley is chamfered at the shaft bore and threaded hole for easy installation, reducing assembly time by 27% compared to the timing pulley not chamfered.

MISUMI Timing Pulley Assembly Time

* The values above are averages of test data and may vary individually.

■Longer Timing Belt Life
·MISUMI Economy series timing pulley, with deburring treatment at the threaded hole, is not easy to wear the timing belt, and the price is cheap while increasing the lifetime of the timing belt.

Belt condition after the test of timing belt pulley without chamfer on the threaded hole:
there are obvious wear marks left by the pulley tooth threaded hole on the belt tooth surface.

[Test conditions]
Belt series: S5M
Belt width: 150mm
Number of teeth of drive side pulley: 20

Precautions

There may be no surface treatment in the shaft hole.

The positions of keyway and tooth are not fixed.

Example of Use

Example drawing of a workpiece reversal transfer mechanism designed using MISUMI timing pulley

■Mechanism name
Workpiece Reversal Transfer Mechanism

■ Mechanism function
The workpiece moving on the conveyor belt rotates 90 degrees and then transfers to the next process.
At this time, the clamping mechanism rotates 180 degrees and does not change the direction of the workpiece relative to the conveying direction at the same time during transfer.

■Role of the timing pulley
The transmission of the timing pulley and the timing belt changes the placement direction of the workpiece while transferring the workpiece. (Applicable to S specification and GT specification timing pulleys)
