Welcome to our newly redesigned website!
The Lumina swivel castor with intermittent brake is a precision-engineered mobility solution designed for demanding applications requiring reliable directional control and load management. The castor features a stem with grip ring and collar fitting, which provides secure installation and enhanced handling capabilities for integration into various equipment configurations. The housing is constructed from polypropylene and incorporates a stem swiveling mechanism that enables smooth 360-degree rotation, facilitating effortless manoeuvrability in confined spaces and complex layouts. The wheel assembly comprises a 50 mm diameter wheel mounted on a plain bearing with spacer tube, ensuring consistent rotational performance and extended operational life. The wheel tread is manufactured from thermoplastic rubber with electric-conductive properties, whilst the wheel body is constructed from electric-conductive polypropylene, making this castor particularly suitable for environments where electrostatic dissipation is critical. The overall height of the castor measures 61 mm, providing a compact profile suitable for space-constrained applications. The load capacity specifications indicate a static load rating of 80 kg and a dynamic load rating of 40 kg at speeds up to 3 km/h, ensuring safe operation across a broad range of applications. The Lumina castor is ideally suited for bedside tables, furniture, media furniture, office furniture, and office chairs, where smooth mobility, directional control, and electrostatic safety are essential requirements.

Swivel castor 50 mm
Lumina
A520YGI050B10-11X20/10DOM38 9011

The Lumina swivel castor is a precision-engineered mobility solution designed for applications including bedside tables, furniture, media furniture, and office furniture. The castor features a stem with grip ring and collar fitting that provides secure attachment and reliable performance in demanding environments. The housing is constructed from polypropylene and incorporates a stem swiveling mechanism that enables smooth, multidirectional movement whilst maintaining structural integrity. The wheel assembly comprises a 50 mm diameter wheel with a plain bearing and spacer tube configuration, ensuring smooth rotation and extended operational life. The wheel tread is manufactured from thermoplastic rubber with electric-conductive properties, whilst the wheel body is constructed from electric-conductive polypropylene, making this castor suitable for static-sensitive applications where electrostatic discharge prevention is critical. The overall height of the castor is 61 mm, providing a compact profile suitable for integration into various furniture designs. The load capacity specifications indicate a static load rating of 80 kg and a dynamic load rating of 40 kg at a maximum speed of 3 km/h, ensuring reliable performance under typical operational conditions. This combination of materials, bearing technology, and load specifications makes the Lumina swivel castor an ideal choice for applications requiring both mobility and electrostatic control properties.
