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
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.

50mm Pressed Steel Fixed Castor — Black Polypropylene Wheel, 4-Bolt Top Plate, 65 kg Load Capacity
A compact, robust fixed castor engineered for reliable straight-line mobility across furniture, display units, and light industrial equipment. Constructed with a pressed steel top plate and a durable polypropylene wheel, this castor delivers consistent, low-maintenance performance in commercial and domestic settings alike.
This 50 mm fixed castor is purpose-built for applications where controlled, directional movement is required. Unlike swivel castors, the fixed configuration keeps the wheel aligned in a single plane, making it the preferred choice for the rear positions of trolleys, carts, and furniture frames where straight tracking is essential.
The pressed steel top plate provides a rigid, secure mounting surface, while the 4-bolt hole pattern ensures a firm, vibration-resistant connection to the host structure. The black polypropylene wheel offers a practical balance of hardness and resilience, performing reliably on smooth concrete, tile, vinyl, and laminate flooring without marking or excessive noise. With a rated load capacity of 65 kg per castor and a combined capacity of 195 kg across a set of four, this unit is well suited to a broad range of light-to-medium duty tasks.
Commonly specified for office furniture, retail display stands, hospitality trolleys, workshop benches, and storage units, this fixed castor is a dependable, cost-effective mobility solution for everyday professional use.
