Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
Enter the weight of the item plus its heaviest load. This castor is rated 75kg each.
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.
Floors & use
Nylon / polypropylene wheel
- Very easy to push, even when loaded
- Resists water, oil and many chemicals
- Hard-wearing and easy to wipe clean
- Best on smooth concrete and hard floors
- Noisier than rubber or polyurethane
- Hard tread can mark or damage soft and delicate floors
- Rolls poorly over debris and cables
Details & FAQs
75mm Pressed Steel Fixed Castor Wheel — Black Polypropylene Wheel, 4-Bolt Top Plate, 75kg Load Capacity
This 75mm fixed castor wheel features a pressed steel top plate with a four-bolt mounting configuration and a black polypropylene wheel. Designed for stationary directional use, it delivers reliable load-bearing performance across a wide range of light-to-medium duty applications — including office furniture, workshop benches, retail display units, shelving, and warehouse trolleys. With a 75kg individual load rating and a combined four-castor capacity of 225kg, it is a dependable choice wherever controlled, fixed-direction mobility is required.
- Fixed Castor Design: Provides straight-line directional movement with no swivel action, ensuring stability and controlled mobility.
- Pressed Steel Top Plate: Zinc-plated steel plate construction offers strength and corrosion resistance for long-term durability.
- Black Polypropylene Wheel: Hard-wearing thermoplastic wheel suited to smooth and semi-smooth indoor floor surfaces.
- 75kg Individual Load Capacity: Rated to support up to 75kg per castor, with a combined four-castor maximum of 225kg.
- 4-Bolt Hole Mounting: Standard four-bolt top plate for secure, straightforward installation onto equipment frames and furniture bases.
- Plain Bearing: Low-maintenance bearing type suited to moderate-speed, consistent-load applications.
- Zinc-Plated Finish: Provides a clean, professional appearance and added resistance to surface oxidation.
- Compact 75mm Wheel Diameter: Balances ground clearance with a low overall castor height, ideal for space-conscious installations.
Technical Specifications
Typical Applications
Office Furniture Suitable for desks, workstations, and storage units where fixed, stable movement is preferred over free-swivel rotation.
Warehouse & Storage Ideal for shelving bays, picking trolleys, and light goods handling equipment in distribution and storage environments.
Workshop & Industrial Well-suited to tool cabinets, workbenches, and equipment stands requiring directional movement across workshop floors.
Retail & Display Provides controlled mobility for display stands, gondola units, and point-of-sale fixtures in retail environments.
Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor moves in a single straight-line direction only — it does not rotate on a vertical axis. A swivel castor, by contrast, can turn 360 degrees, allowing multi-directional movement. Fixed castors are typically used in combination with swivel castors to provide directional control and stability, or alone on equipment that only needs to move in one direction.
How do I calculate the correct load capacity for my application?
To determine the required load capacity per castor, divide the total weight of the loaded equipment by the number of castors being fitted, then apply a safety margin of approximately 30–40%. For this castor, the individual rating is 75kg, with a combined four-castor maximum of 225kg. Always base your calculation on the maximum loaded weight, not the empty weight of the equipment.
Is this castor suitable for use on hard floors such as concrete or tile?
Yes. The polypropylene wheel is well-suited to smooth and semi-smooth hard floor surfaces including concrete, tile, vinyl, and laminate. It is a hard wheel material, which means it rolls efficiently on firm surfaces but is not recommended for use on soft, uneven, or heavily textured flooring where a rubber or polyurethane wheel would be more appropriate.
What bolt size is required for the 6mm plate holes?
The top plate features four mounting holes with a 6mm diameter, which are compatible with M6 bolts or screws. The hole centres measure 48mm and 38mm across both the length and width of the plate, giving you two bolt-pattern options to suit different equipment frames. Always ensure the fasteners used are rated to the load requirements of the application.
* Load capacity figures are provided as a guide under normal operating conditions on suitable floor surfaces. Actual performance may vary depending on floor condition, speed of movement, temperature, and the distribution of load across all fitted castors. Always verify suitability for your specific application before installation.
