Are CTS Roller Chains Prestretched?

Are CTS Roller Chains Prestretched?

Yes, our roller chains are typically pre-stretched during the manufacturing process to improve dimensional stability and reduce initial elongation during operation.

Pre-stretching is performed by applying a controlled load to the chain after assembly. This process helps to seat the pins and bushings properly, minimize internal clearances, and stabilize the chain structure before it is put into service.

As a result, pre-stretched chains typically exhibit reduced initial wear, improved dimensional stability, improved sprocket engagement, and reduced need for frequent retensioning.

However, it is important to note that pre-stretching does not eliminate chain elongation over time. Proper lubrication, correct installation, and regular maintenance are still essential to ensure long service life.
