Pressed Steel Fixed Castors With Black Polypropylene Wheel — 50mm to 100mm
Top Plate Fitting | Plain Bearing | UK Stock | Three Size Options
These pressed steel fixed castors are designed to provide reliable, straight-line movement for a wide range of light-duty indoor applications. Each castor features a moulded black polypropylene wheel mounted within a robust pressed steel bracket, secured to equipment via a four-hole top plate — one of the most common and versatile fixing methods in commercial and domestic settings.
Available in three wheel diameters — 50mm, 75mm, and 100mm — these fixed castors are suited to furniture, storage units, trolleys, display equipment, and general-purpose handling tasks where directional stability is required. The plain bearing construction keeps the design simple, cost-effective, and easy to maintain, making these castors an ideal choice for environments where budget efficiency and dependable performance are equally important.

* Load ratings are per individual castor. To calculate the required load capacity per castor, divide the total equipment weight (including contents) by the number of castors fitted — typically four. Always apply an appropriate safety margin to account for dynamic loads, uneven weight distribution, and floor surface conditions.

The 50mm fixed castor is the most compact option in this range, making it well suited to smaller items of furniture and lightweight equipment where ground clearance is limited and a low overall height is desirable. With a total castor height of just 72mm and a load capacity of 65kg per unit, it delivers dependable straight-line movement without adding unnecessary bulk. The four-hole top plate measures 60mm x 67mm with dual hole centre options of 48mm and 38mm, providing compatibility with a wide variety of standard furniture frames and equipment bases. The 22mm tread width ensures adequate floor contact for stable rolling across smooth indoor surfaces.

The 75mm fixed castor represents the mid-range option in this selection, offering a practical balance between manoeuvrability and load-bearing capability. At a total height of 100mm and a load rating of 75kg per castor — supporting up to 225kg across a set of four — it is well positioned for general commercial use where equipment is moved regularly but directional control is more important than full swivel capability. The shared top plate dimensions (60mm x 67mm, 6mm hole diameter, dual hole centres of 48mm and 38mm) ensure straightforward installation on standard equipment frames, and the 22mm tread width provides even weight distribution across smooth and semi-smooth floor surfaces.
- Workshop tool cabinets, benches, and mobile storage units requiring directional stability
- Warehouse shelving, picking trolleys, and goods transport equipment
- Commercial kitchen equipment and catering trolleys on smooth floor surfaces
- Retail gondola shelving and display fixtures in supermarket and shop environments
- Office furniture including filing cabinets, printer stands, and mobile pedestals
- Healthcare and institutional trolleys in clinics, schools, and care facilities

The 100mm fixed castor is the largest and highest-capacity option in this range, designed for applications where greater ground clearance, improved rollability over minor floor irregularities, and a higher load rating are required. With a total height of 122mm and a per-castor load capacity of 85kg — equating to 255kg across a standard set of four — this option is suited to heavier equipment and more demanding handling environments. The larger wheel diameter also reduces rolling resistance compared to smaller sizes, making it easier to push loaded equipment across longer distances. The top plate dimensions remain consistent with the other sizes in this range (60mm x 67mm, 6mm hole diameter, 48mm and 38mm hole centres), ensuring compatibility with the same range of equipment frames.
