Frequently Asked Questions
What is the maximum load this castor can support?
Each castor is rated to 50kg. When fitting a set of four, the combined maximum load is 150kg — calculated using a standard 25% safety factor to account for uneven load distribution and dynamic movement.
Will this castor scratch or mark my floor?
The grey rubber tread is a non-marking compound designed to roll quietly and cleanly on hard floor surfaces including tile, vinyl, laminate, and sealed concrete. It is a practical choice for retail, office, and hospitality environments where floor protection matters.
How do I fit this castor to my equipment?
The castor mounts via a 4-hole top plate measuring 50mm × 50mm, with hole centres at 36mm × 36mm and a hole diameter of 6mm. It is secured using four M6 bolts (not supplied). Ensure the mounting surface is flat and structurally sound before fitting.
Is this castor suitable for outdoor use?
This castor is designed primarily for indoor use on smooth, hard floor surfaces. The zinc-plated pressed steel housing offers a degree of corrosion resistance, but prolonged exposure to moisture, standing water, or outdoor conditions is not recommended and may affect performance over time.
Sold individually. Fixings not included. For best results, select a castor rated to at least 25% above your anticipated load. If you require a braked version, fixed castor, or a higher load rating, please refer to the full castor range.
