Welcome to our newly redesigned website!
The Lumina swivel castor with intermittent brake is a precision-engineered mobility solution designed for demanding applications including bedside tables, furniture, media furniture, office furniture, and office chairs. The castor features a stem with grip ring and collar fitting, which provides secure and reliable attachment to various furniture bases whilst allowing for straightforward installation and maintenance. The housing is constructed from polypropylene and incorporates a stem with swiveling capability, enabling smooth multidirectional movement and enhanced manoeuvrability in confined spaces. The wheel assembly comprises a 50 mm diameter wheel with a plain bearing and spacer tube configuration, 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, facilitating integration into compact furniture designs without compromising stability or aesthetic considerations. 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, providing robust performance for typical office and domestic furniture applications. This combination of materials, engineering, and load specifications ensures reliable operation across diverse indoor environments whilst maintaining the safety and durability standards required for professional and residential use.

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

The Lumina swivel castor is a precision-engineered mobility component 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 easy installation to compatible furniture bases. The housing is constructed from polypropylene and incorporates a stem swiveling mechanism that enables smooth 360-degree rotation, allowing furniture to be manoeuvred with minimal effort and maximum directional control. The wheel assembly comprises a 50 mm diameter wheel mounted on a plain bearing with spacer tube, ensuring reliable and consistent performance across extended operational periods. The wheel tread is manufactured from thermoplastic rubber with electric-conductive properties, whilst the wheel body is constructed from polypropylene with electric-conductive characteristics, making this castor suitable for environments where electrostatic dissipation is required. The overall height of the castor measures 61 mm, providing a compact profile that integrates seamlessly into contemporary furniture designs. The castor demonstrates a static load capacity of 80 kg per unit, with a dynamic load capacity of 40 kg when operating at speeds up to 3 km/h, making it suitable for light to moderate duty applications requiring reliable mobility and stability.
