Heavy-Duty AGV & Towline Continuous Duty Casters

The AstraRoll Technical Advantage: Engineered for Automation
AGV and Towline engineers face three major mobility enemies: Heat, Battery Drain, and Bearing Wear. We conquer all three:

Zero-Melt High-Rebound Polyurethane: Continuous rolling creates internal friction, which builds heat. Standard PU wheels will hit their glass transition temperature and literally peel off the metal hub (delamination). AstraRoll utilizes a premium, high-rebound polyurethane compound that runs exceptionally cool, surviving 24/7 operations while protecting epoxy warehouse floors.

Optimized AGV Swivel Lead: AGVs frequently perform zero-radius pivot turns. If the caster's swivel lead (the offset distance from the center of the mounting plate to the axle) is too short, the wheel "scrubs" against the floor, draining the vehicle's battery. We custom-engineer the swivel geometry to provide fluid, low-resistance rotation.

Indestructible Drop-Forged Rigs: We do not use stamped steel for this series. The top plates and yoke bases are hot-forged from solid steel, then CNC-machined to house massive thrust bearings. This guarantees the raceway will not brinell (dent) under continuous heavy payload vibrations.

Energy-Saving Precision Bearings: To maximize AMR/AGV run time between charges, we seal precision tapered roller bearings in both the wheel hub and the swivel raceway. This reduces rolling resistance to an absolute minimum.

Why Choose AstraRoll? (Your OEM Automation Partner)

Direct Engineering for AGV Builders: We speak the language of robotics engineers. Bring us your vehicle's payload data, max speed, duty cycle, and battery constraints, and our factory will custom-build a caster profile with the precise swivel lead and durometer needed to optimize your machine's performance.

Stop Paying Distributor Markups: High-performance forged casters are incredibly expensive through catalog distributors. By partnering directly with the AstraRoll manufacturing facility, AGV integrators and automotive assembly plants secure elite, continuous-duty components at direct B2B pricing.

Frequently Asked Questions (FAQs)

Q: Why can't I just use a high-capacity standard caster for an AGV?
A: Standard casters, even heavy-duty ones, are designed for manual pushes (walking speed, intermittent resting). An AGV runs continuously at higher speeds. Without a resting period, a standard caster's bearings will overheat, and the wheel tread will delaminate and fail. You must use a "Continuous Duty" rated caster.

Q: How does the wheel material affect my AGV's battery life?
A: Rolling resistance directly impacts power consumption. A softer or lower-quality polyurethane absorbs energy as it compresses and rolls. AstraRoll's High-Rebound Polyurethane acts like a highly inflated tire, returning energy to the roll and significantly extending your AGV's operational time between charges.

Q: Can you customize the overall height to match our vehicle chassis?
A: Yes. As a direct manufacturer, we frequently modify yoke heights, top plate dimensions, and bolt-hole patterns to act as seamless drop-in replacements for your existing automated vehicle chassis designs.

Q: Do these casters require maintenance?
A: While they are highly sealed against dust and debris, 24/7 operation requires lubrication. We equip all continuous duty casters with easily accessible Zerk grease fittings on both the swivel raceway and the wheel axle to fit perfectly into your facility's preventative maintenance schedule.

Q1. Are you a trader or direct factory?

We are a direct manufacturing factory with over 20 years of expertise in high-end industrial rollers, casters and material handling solutions. Our facility operates with ISO-certified quality management systems, allowing us to maintain full control over production cycles and quality standards. Throughout two decades of growth, we have established deep, long-term strategic partnerships with several listed companies and global automation leaders, proving our reliability as a high-tier industrial supplier.

Q2. What are your main products?

AstraRoll specializes in the engineering and production of three core product lines: Industrial Rollers, Heavy-Duty Wheels, and Precision Casters. We do not just sell components; we provide integrated movement and transport solutions. Our products are widely utilized across high-demand sectors, including: New Energy, Lithium Battery, Mining, Heavy Industry, Medical Institutional, Agriculture and Logistics.

Q3. What about delivery time?

We deeply understand that project timelines are critical. Our delivery schedule is generally structured as follows:
Standard Products: Usually dispatched within 7–15 working days if the components are in stock.
Customized/OEM Orders: Depending on the complexity and volume, the lead time typically ranges from 20–35 days. This includes time for technical drawing confirmation, specialized tooling, and rigorous pre-shipment testing.
Shipping Methods: We offer flexible global logistics solutions, including FOB and CIF terms. We ship via Sea Freight (for bulk industrial orders), Air Freight (for urgent project needs), and International Express (DHL/FedEx/TNT) for smaller components or samples.

Q4. How can I get a quote for customized products?
