Details & FAQs
The 80mm Pressed Steel Fixed Castor with Grey Cast Iron Wheel is a robust, non-swivelling castor engineered for demanding industrial and commercial environments. Mounted via a 4-bolt top plate, it is designed to provide straight-line directional stability on heavy-duty trolleys, workshop benches, industrial racking, warehouse equipment, and furniture carts. With a rated load capacity of 120kg per castor — supporting up to 480kg across a set of four — this castor delivers dependable, long-service performance wherever controlled, linear movement is required.

Typical Applications
This fixed castor is well suited to industrial trolleys and platform trucks, warehouse racking and shelving units, workshop benches and machinery bases, heavy-duty furniture and display carts, and manufacturing or production line equipment where straight-line travel is essential. The cast iron wheel performs reliably on concrete, stone, and other hard industrial floor surfaces.
Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor rolls in one direction only, providing straight-line stability and directional control. A swivel castor rotates 360 degrees, allowing movement in any direction. For most trolleys and carts, a combination of two fixed castors at the rear and two swivel castors at the front gives the best balance of control and manoeuvrability.
Is a cast iron wheel suitable for use on smooth or polished floors?
Cast iron wheels are best suited to rough, hard industrial surfaces such as concrete, stone, or compacted earth. They are not recommended for polished, tiled, or sensitive floor surfaces, as the hard tread can cause marking or surface damage. For smooth or finished floors, a rubber or polyurethane-wheeled castor would be more appropriate.
How do I know if this castor will fit my equipment?
Check that your equipment's mounting plate accommodates a 4-bolt fixing pattern with hole centres of 60 mm x 80 mm and a hole diameter of 10 mm. The total castor height is 106 mm — ensure this is compatible with the clearance and height requirements of your application. If you are unsure, please contact us before ordering.
Can I use four fixed castors together, or do I need swivel castors as well?
Using four fixed castors together is possible but limits movement to a single straight-line direction, making steering very difficult. This configuration is occasionally used on guided rail systems or conveyor lines. For general-purpose trolleys and carts, the standard recommendation is two fixed castors paired with two swivel castors to allow both directional stability and easy steering.
