Custom Double Omni Wheels with Rubber Rollers
Product Overview:
In the engineering of multi-directional robotics and AGVs, standard "single-row" omni wheels possess a critical mechanical flaw: a physical gap exists between each peripheral roller. As the wheel rotates, the payload drops slightly into these gaps, causing severe vertical vibration, encoder read errors, and damage to fragile cargo. The AstraRoll Custom Double Omni Wheel is the definitive engineering solution. By mounting two distinct rows of rollers parallel to each other and offsetting them precisely, the "gaps" of one row are completely covered by the rollers of the second row. This creates a perfectly round, continuous point of ground contact, ensuring buttery-smooth, vibration-free rolling. Furthermore, we equip these wheels with high-resilience, vulcanized rubber rollers. Unlike slippery plastic or hard polyurethane, our rubber rollers provide massive traction on dusty warehouse floors, preventing motor spin-outs while allowing your heavy-duty AGVs to strafe laterally and perform zero-radius turns with absolute precision.

Custom Double Omni Wheels with Rubber Rollers Details
The AstraRoll Technical Advantage
We manufacture our Double Omni wheels to deliver the ultimate balance of heavy payload support, navigation accuracy, and smooth kinematics:
Continuous Ground Contact: The overlapping dual-plate architecture ensures that as one rubber roller leaves the floor, the offset roller on the adjoining plate has already made contact. This eliminates all "clattering" and vertical bumping, making it ideal for transporting sensitive electronics or liquid payloads.
High-Friction Rubber Rollers: A multi-directional wheel is useless if the drive motors simply spin in place on a smooth epoxy floor. Our premium rubber formulation maximizes the coefficient of friction, ensuring that every ounce of motor torque is translated into precise, slip-free acceleration and deceleration.
Heavy-Duty Dual Core Architecture: Supporting a heavy industrial payload on small peripheral rollers requires massive structural rigidity. By utilizing two thick CNC-machined aluminum or steel plates bolted together, we double the structural integrity of the wheel, easily supporting hundreds of kilograms per wheel.
Independent Bearing Isolation: Lateral strafing puts immense side-thrust on the small roller axles. We press high-grade miniature ball bearings into both ends of every single rubber roller, guaranteeing they spin effortlessly when the robot moves sideways, even when pinned under a massive static load.

Why Choose AstraRoll?
1. Turnkey Robotic Mobility Solutions
Calculating kinematics for holonomic platforms can be highly complex. AstraRoll acts as your technical partner, providing not just the wheels, but fully matched sets complete with custom motor coupling hubs, ensuring that the wheels mount flawlessly to your planetary gearboxes or stepper motors right out of the box.
2. Specialized Rubber Compounding
Not all factory floors are the same. If your automated vehicle operates in a specific environment, we can custom-compound the rubber rollers. We offer Anti-Static (ESD) Rubber for electronics manufacturing, Non-Marking Grey Rubber for commercial floors, and Oil-Resistant NBR for automotive assembly lines, ensuring your wheels survive your specific facility hazards.
Frequently Asked Questions (FAQs)
Q: Double Omni vs. Mecanum wheels for my AGV?
A: Mecanum wheels must be driven in a strict 4-wheel configuration and require complex control software. Omni wheels are much more versatile; they can be driven or used simply as unpowered, free-spinning support wheels alongside standard drive wheels without complex programming.
Q: Can I replace worn rubber rollers without buying a new wheel?
A: Yes. Our heavy-duty series (152mm/6" and above) features a bolt-together dual core. Your maintenance team can easily disassemble the plates to install AstraRoll replacement roller kits, drastically reducing long-term costs.
Q: Are these wheels suitable for outdoor gravel or rough asphalt?
A: No. They are precision-engineered for smooth industrial floors (polished concrete, epoxy). The miniature ball bearings inside the small rollers are sensitive to mud, gravel, and heavy outdoor debris.
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.
