75mm Pressed Steel Swivel Castor Wheel with Brake - White Nylon Wheel & 4-Hole Top Plate - 75kg Load

75mm Pressed Steel Swivel Castor Wheel with Brake ? White Nylon Wheel & 4-Hole Top Plate ? 75kg Load A precision-engineered swivel castor designed for professional and commercial environments where controlled mobility is essential. Fitted with a white nylon wheel and a pressed steel swivel head, this braked castor mounts via a standard 4-hole top plate and supports loads up to 75kg per unit. It is well suited to trolleys, workshop benches, retail display units, mobile shelving, and light industrial equipment ? anywhere that smooth rolling movement and reliable locking are both required. Key Features Wheel Diameter 75mm ? compact footprint with confident load-bearing performance across smooth and semi-smooth surfaces. Integrated Brake Side-lever brake mechanism locks the wheel in place instantly, preventing unintended movement on level and slightly inclined surfaces. Load Capacity 75kg per castor ? a set of four supports a combined maximum of 225kg under standard operating conditions. White Nylon Wheel Hard-wearing nylon construction delivers low rolling resistance, quiet operation, and long service life on hard floors. Pressed Steel Swivel Head Zinc-plated pressed steel housing provides structural rigidity and corrosion resistance in demanding environments. 4-Hole Top Plate Fitting Standard bolt-pattern plate allows straightforward installation on a wide range of equipment frames and platforms. Full 360? Swivel Unrestricted swivel rotation enables precise directional control and easy manoeuvring in confined spaces.

Frequently Asked Questions What is the maximum load this castor can support? Each individual castor is rated to a maximum of 75kg. When fitted as a set of four, the combined maximum load capacity is 225kg. For safety, it is recommended to operate within 75% of the rated maximum to account for dynamic loading, uneven weight distribution, and floor surface variation. How does the brake mechanism work? The castor features a side-lever foot brake that engages directly against the wheel. Pressing the lever down locks the wheel, preventing rotation and unintended movement. Lifting the lever releases the brake and restores full rolling mobility. The brake is designed for use on level or gently inclined hard floor surfaces. What floor surfaces are these castors suitable for? The white nylon wheel is optimised for smooth, hard floor surfaces including concrete, ceramic tile, vinyl, laminate, and sealed timber. The 75 Shore D hardness rating means the wheel does not compress significantly under load, making it less suitable for soft, uneven, or heavily textured surfaces where a softer rubber wheel would be preferable. How do I fit this castor to my equipment? This castor uses a standard 4-hole top plate measuring 60mm ? 60mm with a bolt-hole pattern of approximately 37mm ? 37mm (diagonal centres) and 7mm hole diameter. It is secured using four bolts through the plate into the base frame of your equipment. No specialist tools are required ? a standard spanner or socket set is sufficient for installation. Technical Note: Load ratings stated are for static or slow-speed rolling conditions on smooth, level hard floors. Dynamic loads, high-speed movement, ramp use, or uneven surfaces will reduce effective load capacity. Always verify suitability for your specific application before installation.
