Product Description:
The RKL4590 is a motor power cable manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Intended for servo and spindle installations, it routes drive output to the motor while carrying auxiliary supply lines and protective grounding. By linking drive controllers to moving axes, it secures low-loss power delivery during rapid positioning cycles found in automated assembly lines and machining centers.
Four stranded copper cores of cross-section 4x25.0 mm² handle the main phase currents, and the cable is rated for a continuous working voltage of 300/500 V, making it compatible with most IndraDrive power stages. A rugged outer diameter of 29.8 mm accommodates shielding and insulation yet still fits standardized energy-chain separators. The sheath is formed from PUR (Adhesion-Free, Matte), a material that resists oil, weld spatter, and abrasion while preventing sticking inside cable guides.
Mechanical endurance matches the electrical performance. The cable is verified for 5,000,000 bending cycles in drag-chain service and tolerates traverse accelerations up to 10 m/s², letting gantries accelerate aggressively without stressing conductors. Thermal limits reach +90 °C for fixed routing and are complemented by a conductor resistance of 0.78 Ω/km, keeping I²R losses low even at high current. Minimum dynamic bend radius is 7.5 D, and auxiliary conductors 4 × 1.5 mm² supply brake release or sensor power beside the green-yellow protective earth.
Wake Industrial stocks this cable and offers same-day shipping when schedules are tight. Every purchase is covered by a 1-year warranty that simplifies maintenance budgeting. Quotes issued for the RKL4590 remain valid for 30 days, giving planners a stable price window.
