The Lumina swivel caster features a stem with grip ring and collar fitting system for secure mounting applications. The housing is constructed from durable polypropylene material and incorporates a stem-type swiveling bearing mechanism that enables smooth directional changes. The wheel assembly consists of a polypropylene body with electric-conductive properties, fitted with a thermoplastic rubber tread that also provides electric-conductive characteristics for static dissipation. The wheel operates on a plain bearing system equipped with a spacer tube for enhanced durability and reduced friction. The wheel measures 1.97 inches in diameter, while the complete caster assembly has an overall height of 2.4 inches. This compact design makes it suitable for applications requiring mobility with static control in confined spaces where precise maneuvering is essential.

Swivel caster with intermittend brake 1.97 in
Lumina
A523YGI050B10-11X20/10D45 9011/9011

The Lumina is a swivel caster with intermittent brake designed for versatile mobility applications including bedside tables, furniture, media furniture, office furniture, and office chairs. The caster features a stem with grip ring and collar fitting that provides secure attachment and easy installation to various furniture bases. The housing is constructed from polypropylene material and incorporates a stem swiveling mechanism that enables smooth 360-degree rotation for enhanced maneuverability. The wheel assembly consists of a 1.97 inch diameter wheel with a plain bearing and spacer tube configuration, paired with a thermoplastic rubber tread material that is electric-conductive to dissipate static charges safely. The wheel body is manufactured from polypropylene with electric conductive properties, ensuring both durability and electrostatic protection in sensitive environments. The overall height of the caster measures 2.4 inches, making it suitable for compact furniture designs. The caster demonstrates a static load capacity of 176.37 pounds, while the dynamic load capacity reaches 88.18 pounds at a maximum speed of 1.86 miles per hour, providing reliable performance under typical operational conditions. This combination of materials, bearing design, and load specifications makes the Lumina an ideal choice for applications requiring controlled mobility with static dissipation capabilities.
