50mm Pressed Steel Swivel Castor with Brake & Grey Rubber Wheel
4-Hole Top Plate | 50kg Load Capacity | Zinc Plated Pressed Steel Housing
About This Castor
This 50mm swivel castor is a compact, light-duty mobility solution built for environments where controlled movement and reliable braking are equally important. Fitted with a grey rubber-tyred polypropylene wheel and housed in a zinc-plated pressed steel swivel head, it is designed for smooth, quiet rolling across hard and semi-smooth floor surfaces. The integrated directional brake locks the wheel firmly in place at the press of a foot, making it well suited to retail display units, exhibition stands, mobile workshop trolleys, and light furniture that needs to stay put when stationary. With a 4-hole top plate for straightforward bolt-on installation and a 50kg per-castor load rating, this unit delivers dependable everyday performance in commercial and light industrial settings.
Available in Different Castor Wheel Types

Typical Applications
Frequently Asked Questions
What is the maximum weight this castor can support?
Each castor is rated to carry up to 50kg. When fitting a set of four castors, the combined maximum load capacity is 150kg — not 200kg — as a safety margin is applied to account for uneven weight distribution during movement.
How does the brake work, and is it easy to operate?
The castor features an integrated directional foot brake. Pressing the brake lever down with your foot locks the wheel in place, preventing the castor from rolling. Lifting the lever releases it. No tools are required — it is designed for quick, one-step operation in busy environments.
What floor surfaces is this castor suitable for?
The grey rubber tyre makes this castor best suited to hard, smooth floor surfaces such as vinyl, tile, polished concrete, and laminate. The rubber tread provides a degree of grip and reduces noise during movement. It is not recommended for heavy-duty outdoor use or rough, uneven terrain.
How do I fit this castor to my equipment?
This castor uses a 4-hole top plate fitting method. The plate measures 50mm x 50mm with hole centres at 36mm x 36mm and a hole diameter of 6mm. It bolts directly onto a flat surface using four M6 bolts (not included). Ensure the mounting surface is flat, structurally sound, and capable of supporting the intended load before fitting.
* Load capacity figures are provided as a guide for static and normal dynamic use. Always assess the specific demands of your application — including floor condition, speed of movement, and load distribution — before selecting a castor. If in doubt, choose a higher-rated unit.
