Custom Conductive Rubber Wheel

Product Overview

AstraRoll Static Control Wheels are precision-engineered to eliminate the invisible threat of electrostatic discharge (ESD) in specialized industrial and commercial settings. Whether you are transporting sensitive microchips, operating in a flammable chemical zone, or moving delicate medical instruments, these wheels provide a continuous, reliable path to ground. By effectively bleeding off static charges, they prevent catastrophic component failure and ensure a spark-free work environment.

Component Excellence & Advantages

Specialized Rubber Compound: Our "Volume-Conductive" rubber technology integrates conductive agents throughout the entire tread—not just a surface coating. This ensures that the ESD properties remain permanent and consistent even as the wheel wears down.
Precision Ball Bearings: We utilize high-grade, shielded ball bearings that maintain constant electrical contact between the axle and the tread while ensuring an ultra-low starting resistance for ergonomic handling.
Heavy-Duty Core Options: Available with reinforced nylon, steel, or aluminum cores, our wheels are built to withstand heavy loads (50kg - 600kg+) without deforming, ensuring stability during critical transport tasks.

Product Strategic Advantages

Triple Choice: Unlike standard suppliers, we offer three distinct resistance ranges (Conductive, Dissipative, and Antistatic) to match your facility's specific safety protocols (e.g., ANSI/ESD S20.20).
Superior Floor Protection: The high-elasticity rubber tread acts as a shock absorber, protecting expensive epoxy or cleanroom floors from marking and damage while operating in near-silence.
Certified Reliability: Every batch is rigorously tested for electrical resistivity, providing you with the peace of mind that your equipment is 100% grounded and compliant with international safety standards.

Important Usage Notes

System Grounding: These wheels must be used on conductive or ESD-safe flooring to function.
Maintenance: Keep treads free of oil, wax, or heavy dust, as debris can act as an insulator and increase electrical resistance.
Bearing Choice: We recommend precision ball bearings for these applications to ensure a continuous electrical connection from the axle to the wheel tread.
 
Why Choose AstraRoll's Conductive Rubber(TPR) Wheel?

AstraRoll offers multiple resistance levels (Conductive vs. Antistatic) to match your specific safety protocol.
The elastic nature of our rubber compound ensures the wheels roll silently, absorbing vibrations that could disturb sensitive instruments.
AstraRoll provides specialized grey ESD compounds that offer static protection without leaving carbon marks on cleanroom floors.
Unlike surface-coated "antistatic" wheels, AstraRoll uses volume-conductive materials, meaning the electrical properties will not wear off over time.
From stainless steel housings for medical use to heavy-duty cores for industrial carts, we tailor the caster to your environment.

FAQ

1.Does the floor type affect the performance of these wheels?

Yes, absolutely. For Conductive or ESD wheels to function, they must be used on conductive or grounded flooring. If used on standard insulating surfaces (like thick epoxy, wood, or carpet), the static charge will have no path to the ground and will remain on the cart.

2.Will the conductive properties wear off over time?

No. AstraRoll uses "Volume-Conductive" technology, meaning the conductive agents are integrated throughout the entire rubber compound. Unlike cheap surface-coated wheels, our wheels maintain their electrical properties for their entire service life, even as the tread wears down.

3.Can I get a test report for my specific order?

Yes. We understand the importance of compliance. AstraRoll provides a Resistance Test Report for every batch, verified with calibrated megohmmeters, to ensure the wheels meet your facility’s safety protocols.

4.What are the differences between Conductive, ESD, and Antistatic rubber wheels?

The primary difference lies in their electrical resistance (Ω), which determines how quickly they discharge static electricity.

• Conductive Wheels offer the fastest discharge to prevent sparks in explosive environments.
• ESD (Static Dissipative) Wheels provide a controlled, safer discharge rate for protecting sensitive electronic components (PCBs/Microchips).
• Antistatic Wheels focus on preventing the initial generation of static caused by friction to ensure user comfort and basic safety.
