Swivel Castors with Brake and Red Thermoplastic on White Nylon Wheel — 80mm to 150mm
These pressed steel swivel castors combine a robust double ball bearing swivel head with a directional brake and a distinctive red thermoplastic wheel mounted on a white nylon centre. Available in four wheel diameters — 80mm, 100mm, 125mm, and 150mm — they are engineered for demanding mobility applications across industrial, commercial, and institutional environments. Each castor is fitted with a 4-hole top plate for straightforward bolt-on installation, making them a reliable choice for trolleys, workbenches, shelving units, and heavy-duty equipment that requires both controlled movement and secure stationary positioning.

Frequently Asked Questions
Which size castor should I choose for my application?
The right size depends on the load you need to support and the height clearance available on your equipment. The 80mm castor (90kg capacity) suits lighter trolleys and furniture; the 100mm (110kg) is a versatile all-rounder for general commercial use; the 125mm (160kg) handles heavier industrial loads; and the 150mm (180kg) is the best choice for the most demanding applications where maximum load capacity and rolling ease are required. Always calculate your total load across all four castors and select a size with a comfortable margin above that figure.
What does the directional brake do, and how does it work?
The directional brake is a foot-operated mechanism that locks the wheel to prevent it from rolling, while still allowing the swivel head to rotate. This means the castor can be held stationary without fully immobilising the equipment — useful in environments where you need to park a trolley or workbench securely but may need to pivot it in place. To engage the brake, press the lever down with your foot; to release, lift it back up.
Are these castors suitable for use on smooth concrete or tiled floors?
Yes. The red thermoplastic tread at 85 Shore A hardness is well suited to smooth, hard floor surfaces including concrete, tile, and sealed screed. The hardness level provides excellent durability and wear resistance while still rolling smoothly. These castors are not recommended for soft or uneven outdoor terrain, as the hard tread offers limited shock absorption on rough ground.
How do I fit these castors to my equipment?
Each castor is fitted with a 4-hole top plate measuring 100mm x 85mm. The plate has two sets of hole centres — 60mm and 80mm width — with a hole diameter of 10mm, accommodating M8 or M10 bolts depending on your configuration. Simply align the plate with the pre-drilled holes on your equipment frame and secure with appropriate bolts and nuts. No specialist tools are required for standard installations.
