Overview
This industrial-grade stem caster is engineered specifically for environments requiring strict electrostatic discharge control, such as electronic assembly lines and sensitive component manufacturing facilities. The unit features a 4-inch rubber wheel formulated with anti-static properties to safely dissipate static electricity, protecting delicate electronics from damage during transport. Designed for light-to-medium duty applications, each caster supports a substantial load capacity while ensuring smooth, quiet operation on various floor surfaces. The integrated expanding stem mechanism allows for rapid, tool-free installation into standard receptacles, reducing downtime during equipment setup or maintenance. A reliable foot-activated brake provides secure locking capability, preventing unintended movement when workstations or carts are stationary.
Key Features
Anti-static rubber compound safely dissipates electrostatic discharge Robust expanding stem design ensures secure, tool-free installation Foot-activated brake locks wheel firmly to prevent equipment drift Smooth rolling performance minimizes noise and floor marking High load-bearing capacity suitable for dynamic industrial use Durable construction withstands repeated cycles in demanding settings

Applications
Electronic assembly and testing workstations Sensitive component manufacturing lines Clean room environments requiring static control Light-to-medium duty industrial carts and trolleys Hospitality and healthcare equipment transport where noise reduction is critical Laboratory settings handling static-sensitive instruments The anti-static formulation of the rubber wheel is critical for facilities operating under ESD protection protocols, ensuring that static buildup does not compromise product integrity or worker safety. The 4-inch diameter offers an optimal balance between maneuverability and obstacle clearance, allowing equipment to roll smoothly over minor floor imperfections without excessive effort. With an overall height of 5.1 inches, these casters provide adequate ground clearance for most standard industrial frames while maintaining a low center of gravity for enhanced stability. The expanding stem mechanism eliminates the need for additional hardware or complex tools, streamlining the installation process across large fleets of mobile equipment. Each unit is rigorously tested to maintain its 220 lb load rating under continuous operational stress, making it a reliable choice for facilities that demand both safety and durability. The included foot brake engages positively to hold loads securely in place, which is essential during precision tasks where even slight movement could result in errors or accidents. Sold in packs of six, this solution offers cost-effective scalability for outfitting entire production lines or warehouse zones with compliant mobility solutions.
