Q: How do I calculate the service life of a chainflex® cable?

igus® provides free online tools including a service life calculator and cable configurator. These help you select the right cable and predict its performance in your specific application.

Q: Can I get free samples of igus® chainflex® cables?

Yes. Engineers and purchasing managers can request a free cable sample box to evaluate product performance before committing to larger orders.

Q: Can I get pre-assembled cables with connectors?

Yes. With the igus® readycable® service , cables can be ordered pre-harnessed with connectors from brands like Siemens, Beckhoff, Allen Bradley, and SEW, ready for plug-and-play installation.

Designed for dynamic applications, tested for durability & longevity

chainflex® servo cables are specifically engineered for tight spaces and use in energy chains in dynamic, moving applications. Developed and rigorously tested in the igus® test laboratory, these cables undergo extensive trials under varying conditions, including high speeds and rapid acceleration cycles to ensure exceptional durability, reliability, and long service life.

All chainflex® servo cables meet a wide range of international standards and certifications, including CTP, RoHS, EAC, and CE, among others, providing confidence in their quality and compliance. In addition, they are designed to be flame-retardant and oil-resistant, making them ideally suited for demanding industrial environments such as machinery, automation systems, and production lines.

Benefits:

Bend radius as low as 7.5× cable diameter for long service life, even in moving applications.
Can be grouped with data, control, and other chainflex® cables inside an energy chain.
Up to 10 million double strokes with a 4-year guarantee. Determine precise service life with the chainflex® service life calculator to reduce maintenance and save time.

Dual Shielding for Reliable Servo Cable Performance

chainflex® servo cables feature two types of shielding to ensure safe, interference-free operation in demanding industrial environments:

Overall Shielding: Protects against external electromagnetic interference (EMI), ensuring stable EMC performance and preventing disruption to nearby machine components.
Individual Pair Shielding: Specifically shields brake and temperature sensor pairs, preventing internal interference from power cores that could affect the frequency converter’s control signals.

For high-stress applications, our premium cables offer up to 90% mechanical coverage, using advanced materials and designs that combine robust EMC protection with fast, efficient processing during installation.

Applications with chainflex® cables

Cable in the forklift - a special challenge

An unusual application involves winding and unwinding cables on forklift masts via plastic rollers. The constant pulling and deflection place extreme strain on the cable stranding. After earlier issues, igus® collaborated with the customer to test a solution using specially bundle‑wound cores. This rope construction neutralises internal forces, eliminating corkscrew effects and core breakage. If you’re facing similar cable performance challenges, we can help find the right solution.

Frequently asked questions regarding servo cables

An SY cable is used for applications where mechanical protection is required.

igus® does not produce SY cables, why? SY stands for steel wire braided, and the galvanised steel wire braid are not designed to withstand repeated bending or flexing as the steel braid can fracture or unravel over time.

Alternatively, we offer our e-chains® as mechanical protection. igus® also provide CY and YY cables.
