These conductive caster wheels deliver reliable load-bearing capacity and smooth mobility for a wide range of industrial equipment. They are designed to meet the demands of factory floors, warehouse storage systems and assembly line stations.
The integration of ESD (electrostatic discharge) technology is a key highlight of this product. It prevents static electricity buildup during equipment movement. This feature is essential for environments with sensitive electronic components or materials prone to static damage. The plate-mounted design and built-in brake system ensure stable positioning when needed. It balances flexibility and safety in daily operations.

Superior Electrostatic Control: Our conductive and anti-static TPR casters effectively dissipate static electricity, preventing electrostatic discharge (ESD) that can damage sensitive electronic components, disrupt production lines, or pose risks in flammable environments. This feature ensures a safe and stable working environment.
Excellent TPR Material Properties: Crafted from high-quality thermoplastic rubber (TPR), these casters offer outstanding abrasion resistance, shock absorption, and noise reduction. They can withstand heavy loads while maintaining smooth rolling, reducing floor damage and ensuring quiet operation.
Versatile Design Options: Available in various sizes, load capacities, and configurations, including swivel and fixed types, with or without brakes. This flexibility allows customers to choose the most suitable caster for their specific applications, meeting diverse industrial needs.
Corrosion and Chemical Resistance: TPR material provides excellent resistance to chemicals, oils, and solvents, making these casters ideal for use in harsh industrial environments. They also resist rust and corrosion, ensuring a long service life even in humid or corrosive conditions.
Easy Installation and Maintenance: Designed for quick and hassle-free installation, our casters require minimal maintenance. The durable construction reduces the frequency of replacement, saving both time and cost for our customers.
