PUR Drag Chain Cable – Ultra-Flexible, Abrasion-Resistant for Continuous Motion

Engineered for the most demanding motion applications, LASEN PUR drag chain cables offer extreme abrasion resistance, high tensile strength, and exceptional flexibility, achieving over 5 million bending cycles. The cable resists oil, cold down to -40°C, UV radiation, and flame. It is purpose-built for special control connections, power transmission, and tightly bending routings in harsh automated environments. Manufactured with imported-grade materials and proven design, our specialty PUR drag chain cables consistently outperform typical import-quality alternatives in durability and total service life.

Suitable for both dry and humid indoor installations, these cables are designed for free reciprocating continuous motion without forced guidance—especially where frequent flexing occurs. The cable is typically installed inside cable carriers to prevent tangling, abrasion, snagging, and disarray while the integrated shielding ensures effective protection against electromagnetic interference. Typical applications include CNC machine tools, vertical lathes, glass processing machinery, woodworking equipment, robotic arms, cutting machines, engraving machines, door and window manufacturing lines, and a wide range of automated equipment.

Frequently Asked Questions

What is the minimum bending radius of the PUR drag chain cable?
For fixed installation, the minimum bending radius is 5 times the cable outer diameter. In moving applications, the radius must be at least 7 times the outer diameter to maintain service life.

Can the jacket color and core marking be customized?
Yes. Grey, black, and orange are standard, but we can supply custom jacket colors and core identification (either number coding or color coding) to match your installation and maintenance requirements.

Does this cable provide electromagnetic shielding?
Yes. The ultra-fine galvanized steel wire braid with over 85% coverage delivers excellent EMI shielding performance and simultaneously reinforces the cable against high tensile stress.

What bending life can I expect under continuous flexing conditions?
LASEN PUR drag chain cables are tested to withstand more than 5 million bending cycles. The actual life depends on the bending radius, travel speed, and environmental conditions, and our engineers can help you validate the expected lifetime in your specific installation.

Is the cable suitable for outdoor or cold-environment use?
Absolutely. The PUR outer jacket delivers strong UV resistance, cold flexibility down to -40°C, and resistance to oils and chemicals, making it reliable in outdoor cable carrier systems and in cold-storage or harsh indoor environments.

Which conductor standard does the cable meet?
The conductor consists of super-fine oxygen-free copper strands fully compliant with VDE 0295 Class 6, ensuring maximum flexibility and conductivity for continuous motion applications.
