Description
Pressed Steel Fixed Castors with White Nylon Wheels
A pressed steel fixed castor is a non-swivelling wheel unit bolted directly to the underside of equipment via a 4-hole top plate, providing straight-line directional movement with maximum structural rigidity. This range features a white nylon wheel running on a ball journal bearing, delivering smooth, low-effort rolling across hard floors including concrete, tile, vinyl, and sealed timber. Available in five wheel diameters — 80mm, 100mm, 125mm, 150mm, and 200mm — with individual load ratings from 120kg to 230kg per castor, these units are engineered for trolleys, carts, workbenches, shelving bays, display units, and industrial equipment across warehousing, manufacturing, retail, healthcare, and hospitality environments.

Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor is mounted in a static position and allows movement in one direction only — forwards and backwards along a straight line. A swivel castor rotates 360 degrees, allowing the equipment to be steered in any direction. Fixed castors are typically used in pairs alongside swivel castors: the swivel castors at the front provide steering, while the fixed castors at the rear maintain directional stability and prevent the load from drifting sideways. For equipment that travels in a straight line only — such as racking systems or conveyor-fed trolleys — all four castors may be fixed.
How do I select the correct wheel diameter for my application?
As a general rule, a larger wheel diameter rolls more easily over floor irregularities and reduces the effort required to move a loaded trolley or cart. For smooth, level floors in retail or light commercial settings, the 80mm or 100mm options are well suited. For warehouse and manufacturing environments with concrete floors or minor surface imperfections, the 125mm or 150mm options offer improved rolling performance. The 200mm castor is recommended for the heaviest loads or where the floor surface is less consistent. Always select a castor whose load rating comfortably exceeds the maximum weight it will carry in use.
How is the load capacity calculated when using multiple castors?
Each castor in this range is rated for an individual load capacity — for example, 120kg for the 80mm option. When four castors are fitted to a piece of equipment, the combined maximum load is calculated by multiplying the individual rating by three (not four), to account for uneven weight distribution across the castors in real-world use. For the 80mm castor, this gives a practical combined capacity of 360kg. This conservative calculation is standard practice in castor specification and helps ensure safe, reliable performance over the life of the equipment.
Are these castors suitable for use on tiled or vinyl floors?
Yes. The white nylon wheel at 85 Shore A hardness is well suited to smooth hard floor surfaces including ceramic tile, vinyl, sealed concrete, and timber. Nylon wheels roll cleanly and do not leave marks on these surfaces under normal operating conditions. They are not recommended for use on soft or delicate flooring such as carpet or unfinished wood, where a softer rubber or polyurethane wheel would be more appropriate. For outdoor use or heavily textured surfaces, a larger diameter castor from this range will perform better than a smaller one.
