Product Description:
K331 series Agv robot caster are tow cart dedicated casters that allow very flexible and precise steering. The moderate load capacity is possible in this product, and with the inclusion of a high-precision swivel raceway, the Agv caster is designed to allow flexible, quiet rotation along with excellent wear resistance, which makes the caster suitable for continuous duty operation.
The combined bearing structure of a thrust ball bearing and a tapered roller bearing is the type of structure of the swivel raceway, which features high precision, flexible rotation, and noise-free operation. Legs are formed by one-piece deep drawing, which results in a good-looking product resistant to deformation. The bracket metal surface is zinc plated and sealed; salt spray resistance can meet 76 hours. The maximum load capacity of the bracket reaches up to 600 kg, which makes it suitable for equipment with high requirements for steering flexibility, and it also supports powered low-speed applications.


Advantages of Agv Caster Wheel:
Composite Bearing Structure, Extending AGV Power System Lifespan:
The composite structure of the thrust ball bearings and tapered roller bearings is taken advantage of here. The composition is designed to support vertical pressure and also perfectly counteract the radial impact force generated by high-speed towing. The extremely low starting resistance substantially diminishes the load on the AGV motor, thus lowering battery power consumption and extending the intervals between maintenance of the power system.
UH High-Rebound Technology, Optimizing "Energy Consumption/Range Ratio":
The standard UH high-rebound polyurethane wheel surface is equipped. The excellent rolling efficiency of the material implies that under the same load, the AGV uses less power, which results in longer distances being covered on one battery charge; also, it has great self-cooling features when operating at high-frequency 24/7, thus avoiding delamination.
Military-Grade Seamless Bracket, Resisting Severe Impacts:
The bracket legs are deep drawn as one single piece, thus completely eliminating the risk of traditional welding points breaking under impact. After a surface treatment that is compliant with the 76-hour salt spray test standard, it is able to maintain its structural strength and is protected from rust and corrosion even in the humid cold chain logistics environment or in electronic cleanrooms.
Millimeter-level steering accuracy ensures stable automatic navigation:
The precision-machined rotating raceways with sealed bearings help in keeping the steering clearance to a minimum. The AGV does not experience shaking or running off the line during the operation, which, in turn, improves the positioning accuracy of a magnetic strip or laser navigation system and results in fewer system false alarms as well as downtime.
K331 Agv Driving Wheel Selection Guide:
102mm (4-inch) - Load capacity 350kg: Low installation height (143mm), ideal for small handling robots with a very low center of gravity.
127mm (5-inch) - Load capacity 400kg: Industry standard specifications, balancing crossability and stability, suitable for most intelligent trolleys.
152mm (6-inch) - Load capacity 450kg: Stronger obstacle crossing capability, easily handling elevator gaps and uneven workshop surfaces.
203mm (8-inch) - Load capacity 500kg: Among the highest rolling efficiency, moving with minimal effort, perfect for long-distance traction and large logistics transfer centers.
