100mm Solid Robot Drive Wheels Manufacturer

The AstraRoll Technical Advantage: Precision Meets Durability
Compact robotics face a unique challenge: they need a small form factor, but they carry heavy batteries and expensive sensors. Standard 100mm wheels crack or slip. We engineered this series for industrial reliability:

Puncture-Proof Solid Rubber: No flats, no air pressure maintenance. Our solid rubber compound absorbs micro-vibrations from the floor, protecting delicate onboard LiDAR and cameras, while the deep grooved tread prevents slipping in wet or dusty warehouse environments.

High Load-Bearing CNC Hub: Molded plastic hubs warp under the continuous torque of DC gear motors. Our hubs are carved from solid 6061 aluminum alloy, ensuring perfect concentricity (roundness). This allows the robot to run at high speeds smoothly, supporting up to 50kg per individual wheel.

Zero-Backlash Motor Integration: Universal brass couplings often loosen over time, causing the robot to "jerk" when changing directions. AstraRoll factory-machines the hub's bore (shaft hole) to the exact millimeter specifications of your motor, integrating keyways or set-screws directly into the aluminum for flawless power transmission.

No-Slip Tire Fitment: The rubber tire is mechanically locked to the aluminum hub using high-pressure industrial presses. It will not peel, slip, or detach from the rim, even during high-torque pivot turns on rough terrain.

Why Choose AstraRoll? (Your OEM Robotics Partner)

1. Scalable Chassis Supply
Whether you are building 10 inspection robots for a power plant or 1,000 food delivery bots for a university campus, we provide consistent, ISO-certified batch production. Every wheel has identical dimensions, ensuring your robot's navigation software never needs to recalibrate for wheel variations.

2. Direct Engineering Support
Need a wider tire footprint for soft terrain? Need the aluminum hub painted in your company's brand colors? Because you are buying direct from the AstraRoll factory, our engineers can rapidly modify the wheel profile, durometer (hardness), and mounting interface to perfectly suit your specific R&D project.

Frequently Asked Questions (FAQs)

Q: Can these wheels be used for outdoor environments?
A: Yes. The solid rubber tread is specifically formulated with UV inhibitors and offers excellent resistance to temperature changes, making it ideal for outdoor security and inspection robots operating on concrete, asphalt, and light gravel.

Q: We use a specific NEMA 23 stepper motor. Can you make the wheel fit our shaft?
A: Absolutely. Instead of forcing you to buy third-party adapter couplings, simply provide us with your motor shaft drawing (e.g., 8mm shaft with a flat D-cut). We will CNC machine the wheel hub to mount directly onto your motor right out of the box.

Q: Will the rubber tire slip off the aluminum hub?
A: No. We design the outer rim of the aluminum hub with a specialized retention lip, and the solid rubber tire is stretched and pressed onto the hub under extreme mechanical force. It is locked in place and will withstand violent direction changes without detaching.

Q: Do you provide caster (passive) wheels to match these drive wheels?
A: Yes. We manufacture matching free-spinning swivel casters with the same exact 100mm height and rubber profile, ensuring your robotic chassis remains perfectly level and aesthetically consistent.

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.
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?
