Pressed Steel Fixed Castors with Black Rubber on Polypropylene Wheel
Four Sizes: 80mm — 100mm — 125mm — 150mm | Load Capacity: 60kg to 130kg per Castor | UK Stock
These pressed steel fixed castors are robust, top-plate-mounted wheels designed for reliable, straight-line mobility across a wide range of commercial, industrial, and institutional environments. Constructed with a zinc-plated pressed steel bracket, a black rubber tread bonded to a polypropylene core and a precision ball journal bearing, they deliver smooth, quiet rolling performance on hard floors, concrete, and light-duty uneven surfaces. Available in four wheel diameters — 80mm, 100mm, 125mm, and 150mm — with load ratings from 60kg to 130kg per castor, this range covers everything from light furniture and storage units to demanding workshop trolleys and institutional equipment. All four sizes share a standardised 100mm x 85mm four-hole top plate with dual hole-centre spacing of 60mm and 80mm, making them straightforward to fit and easy to replace across multiple applications.

* 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, acceleration forces, and uneven weight distribution.

Compact and lightweight — ideal for light furniture, storage units, and domestic equipment| Castor Type | Fixed — Top Plate Fitting |
|---|---|
| Wheel Diameter | 80 mm |
| Total Castor Height | 106 mm |
| Load Capacity (per castor) | 60 kg |
| Max Load — Set of 4 | 180 kg |
| Wheel Material | Black Rubber on Polypropylene |
| Tread Width | 25 mm |
| Tread Hardness | 85 Shore A |
| Bearing Type | Ball Journal |
| Wheel Colour | Black |
| Plate Length | 100 mm |
| Plate Width | 85 mm |
| Hole Centres (Dual Spacing) | 60 mm / 80 mm |
| Plate Hole Diameter | 10 mm |
| Number of Fixing Holes | 4 |
| Bracket Material | Pressed Steel |
| Bracket Finish | White Zinc Plated |
- Light domestic furniture — chairs, side tables, and storage cabinets requiring occasional repositioning
- Small storage trolleys and utility carts in home workshops or garages
- Display units and point-of-sale stands in retail environments with smooth flooring
- Medical and care-home equipment such as bedside lockers and lightweight trolleys
- Office furniture including printer stands, filing pedestals, and mobile shelving
- Catering and hospitality trolleys where compact, low-profile castors are required
The 80mm option is the most compact in this range, making it the preferred choice where floor clearance is limited or where a lower overall equipment height is required. Its 25mm tread width distributes load effectively across light-duty surfaces without marking or indenting softer floor coverings.
100mm Fixed Castor — 75kg Load Capacity
Versatile general-purpose castor for everyday commercial and light industrial use| Castor Type | Fixed — Top Plate Fitting |
|---|---|
| Wheel Diameter | 100 mm |
| Total Castor Height | 127 mm |
| Load Capacity (per castor) | 75 kg |
| Max Load — Set of 4 | 225 kg |
| Wheel Material | Black Rubber on Polypropylene |
| Tread Width | 30 mm |
| Tread Hardness | 85 Shore A |
| Bearing Type | Ball Journal |
| Wheel Colour | Black |
| Plate Length | 100 mm |
| Plate Width | 85 mm |
| Hole Centres (Dual Spacing) | 60 mm / 80 mm |
| Plate Hole Diameter | 10 mm |
| Number of Fixing Holes | 4 |
| Bracket Material | Pressed Steel |
| Bracket Finish | White Zinc Plated |
- Workshop tool carts and equipment trolleys requiring smooth, controlled movement on concrete or tiled floors
- Warehouse picking trolleys and order-fulfilment carts in distribution centres
- Retail gondola units, stockroom shelving, and merchandise display stands
- Catering and food-service trolleys in commercial kitchens and hospitality venues
- School and educational furniture — mobile resource trolleys, AV carts, and library units
- Light industrial assembly benches and component transport trolleys
The 100mm is the most widely specified size in this range, offering an excellent balance between load capacity, rolling ease, and overall equipment height. The wider 30mm tread improves stability under load and reduces rolling resistance on slightly uneven surfaces compared to the 80mm option.
125mm Fixed Castor — 110kg Load Capacity
High-performance castor for demanding industrial, logistics, and institutional environments| Castor Type | Fixed — Top Plate Fitting |
|---|---|
| Wheel Diameter | 125 mm |
| Total Castor Height | 157 mm |
| Load Capacity (per castor) | 110 kg |
| Max Load — Set of 4 | 330 kg |
| Wheel Material | Black Rubber on Polypropylene |
| Tread Width | 37.5 mm |
| Tread Hardness | 85 Shore A |
| Bearing Type | Ball Journal |
| Wheel Colour | Black |
| Plate Length | 100 mm |
| Plate Width | 85 mm |
| Hole Centres (Dual Spacing) | 60 mm / 80 mm |
| Plate Hole Diameter | 10 mm |
| Number of Fixing Holes | 4 |
| Bracket Material | Pressed Steel |
| Bracket Finish | White Zinc Plated |
- Heavy-duty workshop and engineering trolleys carrying tools, parts, and machinery components
- Industrial laundry and linen trolleys in hotels, hospitals, and care facilities
- Warehouse platform trucks and goods-handling equipment in logistics and fulfilment operations
- Institutional catering equipment — large-capacity food service trolleys and heated transport units
- Manufacturing and production line component carriers requiring stable, directional movement
- Mortuary and healthcare transfer equipment where controlled, straight-line movement is essential
The 125mm castor bridges the gap between general-purpose and heavy-duty applications. Its 37.5mm tread width and 110kg per-castor rating make it well suited to environments where loads are substantial but floor surfaces remain reasonably smooth. The larger wheel diameter also improves rollability over minor floor imperfections and threshold strips.
150mm Fixed Castor — 130kg Load Capacity
Maximum capacity — built for the most demanding commercial and industrial applications| Castor Type | Fixed — Top Plate Fitting |
|---|---|
| Wheel Diameter | 150 mm |
| Total Castor Height | 181 mm |
| Load Capacity (per castor) | 130 kg |
| Max Load — Set of 4 | 390 kg |
| Wheel Material | Black Rubber on Polypropylene |
| Tread Width | 40 mm |
| Tread Hardness | 85 Shore A |
| Bearing Type | Ball Journal |
| Wheel Colour | Black |
| Plate Length | 100 mm |
| Plate Width | 85 mm |
| Hole Centres (Dual Spacing) | 60 mm / 80 mm |
| Plate Hole Diameter | 10 mm |
| Number of Fixing Holes | 4 |
| Bracket Material | Pressed Steel |
| Bracket Finish | White Zinc Plated |
- Heavy industrial platform trucks and goods-movement equipment in warehousing and logistics
- Large-capacity laundry and linen trolleys in commercial laundry facilities and large hotels
- Mortuary, post-mortem, and clinical transfer equipment requiring maximum load stability
- Heavy engineering and fabrication workshops — component transport over concrete and workshop floors
- Bulk storage and archive trolleys in libraries, records management, and document storage facilities
- Agricultural and horticultural equipment — produce transport trolleys in packhouses and cold stores
The 150mm is the largest and highest-capacity option in this range. The rubber tread is bonded to a Polypropylene wheel centre, providing additional structural rigidity under sustained loads. The 40mm tread width and 181mm overall height make this castor particularly effective on rougher floor surfaces and in environments where equipment is moved over longer distances.
