Load check
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

Pressed Steel Swivel Castors with Black Polypropylene Wheel — 50mm to 100mm
A robust, light-duty swivel castor engineered for smooth, reliable mobility across a wide range of indoor environments. Constructed with a pressed steel housing and a solid black polypropylene wheel, these castors are designed to mount quickly via a four-hole top plate and deliver consistent performance under load. Available in three wheel diameters — 50mm, 75mm, and 100mm — each size is rated to a specific load capacity, making it straightforward to select the right castor for your application.

Frequently Asked Questions
How do I choose the right wheel diameter for my application?
As a general rule, a larger wheel diameter rolls more easily over uneven surfaces and distributes load more effectively, making it better suited to heavier or more demanding applications. The 50mm option is ideal for compact, light-duty use; the 75mm suits medium-duty environments with moderate loads; and the 100mm is the preferred choice where higher load capacity and greater ground clearance are required. Always ensure the total height of the castor is compatible with the clearance available on your equipment.
Are these castors suitable for use on hard floors such as tiles or concrete?
Yes. The solid black polypropylene wheel is well suited to hard, smooth, and semi-smooth indoor floor surfaces including concrete, tile, vinyl, and laminate. Polypropylene is a hard-wearing material that performs reliably on these surfaces. It is not recommended for use on soft, carpeted, or heavily textured floors where a softer wheel compound would be more appropriate.
What does the 4-hole top plate configuration mean, and how does it affect fitting?
The 4-hole top plate is the mounting interface that attaches the castor to your equipment. It features four bolt holes arranged in a square or rectangular pattern, allowing the castor to be bolted securely to a flat surface. The plate dimensions are 60mm × 60mm across all three variants, with hole centres of approximately 48mm × 48mm diagonally. This standardised plate size makes it straightforward to replace existing castors or fit these units to new equipment without modification.
Can these castors be used outdoors?
These castors are designed and rated for indoor use on hard, smooth surfaces. While the polypropylene wheel material has reasonable resistance to moisture, the pressed steel housing may be susceptible to corrosion if exposed to outdoor conditions, wet environments, or prolonged contact with moisture. For outdoor or wet-area applications, a castor with a stainless steel or zinc-plated housing and a suitable wheel compound would be a more appropriate choice.
