Product Description:
The RKL4505 motor power cable is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. As a pre-assembled power line for servo axes, it links drive controllers to synchronous motors in automated equipment, carrying mains current and auxiliary signals while tolerating continuous drag-chain motion. The cable simplifies routing inside packaging machines, palletising cells, and machining centres where reliable energy transfer is required for precise, closed-loop positioning.
The round overall diameter of 14.8 mm defines conduit size and clamping hardware, while the power conductors have a cross-section of 2.5 mm², enabling the drive to deliver rated phase current with limited voltage drop. Four auxiliary cores sized 4 x 1.0 mm² are integrated for thermal sensors or holding-brake supply, reducing the need for separate feedback wiring. Mechanical installation is guided by a minimum fixed bending radius of 5 x D, whereas routing through moving energy chains may follow the larger 7.5 x D limit to protect insulation. These geometry rules keep the dielectric structure intact when the cable flexes thousands of times per shift.
Service endurance is further supported by a drag-chain rating of 5,000,000 bending cycles, verifying suitability for high-duty traversing axes. The cable can be laid permanently in environments from -30 to +40 °C and operated in moving applications between -20 to +40 °C without loss of elasticity, while the conductor insulation itself remains stable up to +80/+90 °C during current flow. A matte, adhesion-free PUR outer jacket resists cutting fluids and prevents sticking inside cable tracks, maintaining low friction and quiet motion. Together these thermal, chemical, and dynamic properties allow the RKL4505 to supply power reliably across long service intervals even in confined, constantly moving machine compartments.
