Anti-static wheel Lumina

rubberpolypropyleneswiveling

Overview
The Lumina swivel castor with stem and collar fitting provides secure mounting for industrial and commercial applications. The polypropylene housing integrates a stem-based swivel bearing for smooth directional changes under load. The wheel assembly features an electrically conductive polypropylene body with a thermoplastic rubber (TPR) tread that maintains conductivity during operation. The wheel runs on a plain bearing with an integrated spacer tube to reduce friction and increase durability. Wheel diameter: 50 mm; overall height: 61 mm, suitable for compact installations where space is limited. This configuration is intended for applications requiring electrostatic discharge protection while preserving mobility performance.
