Industrial Triple Rotacaster Omni Wheels for Heavy Robotics

The AstraRoll Technical Advantage

We manufacture our triple-row wheels to deliver the ultimate balance of payload capacity, navigation accuracy, and ergonomic smoothness:

Continuous 3-Point Floor Contact: The overlapping architecture ensures that the wheel never drops into the "valleys" between rollers. This provides a fluid, clatter-free rotation, protecting sensitive robotic sensors from vibration and reducing push-strain for manual warehouse workers.

Self-Stabilizing Geometry: A triple-row wheel acts like a miniature tracked vehicle. Its wider footprint distributes the load over a larger surface area, preventing the wheel from twisting or buckling under heavy side-loads during rapid lateral strafing.

Indestructible Polymer Core: Instead of brittle plastics, our injection-molded cores utilize high-impact engineering polymers (like Acetal/POM). They are immune to rust, highly resistant to industrial chemicals, and will not shatter when dropped down stairs or slammed into dock plates.

High-Friction TPE/PU Rollers: A multi-directional wheel is useless if it simply skids across the floor. Our custom-compounded PU and TPE rollers provide exceptional coefficient of friction, ensuring precise motor odometry for AGVs and safe, slip-free pulling for manual hand trucks.

Key Specifications

Please note: We provide standard catalog sizes as well as custom-machined bores for OEM robotics integration.

Standard Outer Diameter (O.D.): 125mm (5") is the industry standard for hand trucks and medium AGVs.
Wheel Architecture: Triple-Row Offset.
Load Capacity: Ranging from 115 kg (250 lbs) per wheel (Polymer core) up to 200+ kg per wheel (Aluminum core).
Roller Hardness: Typically 85A to 95A Shore for optimal grip and wear resistance.
Operating Temperature: -20°C to +60°C.

Why Choose AstraRoll?

1. Turnkey Hand Truck & Dolly Upgrades

If you are an OEM manufacturing aluminum hand trucks or delivery dollies, replacing standard wheels with AstraRoll Triple-Row wheels instantly adds massive value to your product. It allows delivery drivers to easily slide heavy loads sideways through narrow doorways and maneuver effortlessly inside tight truck beds without tipping the load.

2. Precision AGV Motor Matching

For robotic engineers, dealing with runout and wobbly wheels ruins holonomic navigation. AstraRoll acts as your technical partner, custom-machining the central hub coupling with exact bore diameters, keyways, or threaded mounting holes to perfectly mate with your NEMA stepper motors or planetary gearboxes right out of the box.

Frequently Asked Questions (FAQs)

Q: Can these triple-row wheels be used outdoors or for stair-climbing?
A: Yes. Unlike precision double-omni wheels, which are strictly for indoor polished concrete, the rugged polymer and TPE construction of the 125mm triple-row wheel is specifically designed to handle rougher terrain. They are frequently used on the rear kickstands of manual hand trucks to assist in bumping up and down stairs or curbs without fracturing.

Q: Do I need four Triple-Row Omni wheels to make an AGV move sideways?
A: Yes, if you are building a holonomic platform. You can use three or four wheels driven by independent motors. By programming the motors to spin in opposing or cooperative directions, the vector forces combine to allow the robot to strafe sideways or spin in place without steering mechanisms.

Q: Will the polyurethane rollers leave marks on commercial floors?
A: No. Both our Polyurethane (PU) and Thermoplastic Elastomer (TPE) roller compounds are 100% non-marking. They are perfectly safe for use on retail tiles, hospital vinyl, and polished warehouse epoxy without leaving dark scuffs or scratches.

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.
