The JQR07310 Series is engineered for high-tonnage Autonomous Mobile Robots (AMRs) that operate on maintained industrial floors. With a load capacity of 550kg to 600kg, this series utilizes a twin-wheel architecture to distribute heavy vertical loads while significantly reducing the physical footprint. By integrating a high-precision ball-bearing swivel head, the JQR07310 provides the elite level of agility and low startup resistance required for heavy-duty robots navigating complex factory layouts.
Key Features & Core Benefits:
Twin-Wheel Differential Movement: The independent rotation of the dual wheels facilitates effortless 360-degree turns. This “differential effect” prevents floor scrubbing and reduces the lateral force required during high-frequency steering cycles.
Elite Precision Swivel Head: Featuring an integrated ball-bearing assembly rather than standard loose-ball races, this series offers consistent, ultra-low swivel resistance even when loaded to its maximum 600kg capacity.
Optimized Power Efficiency: The combination of low rolling resistance and reduced swivel torque directly lowers the energy consumption of the robot’s drive motors, extending mission runtimes.
Stable High-Load Foundation: The wider footprint of the twin wheels provides superior balance for top-heavy AGV platforms, ensuring safety and precision during high-speed travel and material hand-off.
High-Rebound Polyurethane Treads: Specifically formulated for high-mileage industrial durability, ensuring zero floor marking and silent operation across multi-shift schedules.
