125mm Pressed Steel Fixed Castor ? Blue Rubber on Polypropylene Wheel, 140kg Load Capacity
This 125mm pressed steel fixed castor is a robust, non-swivel mobility component designed for applications where directional control and load stability are essential. Fitted with a blue rubber tread bonded to a polypropylene centre wheel, it delivers smooth, quiet rolling across hard and semi-hard floor surfaces. With a rated load capacity of 140kg per castor and a zinc-plated top plate for corrosion resistance, it is well suited to warehouse trolleys, industrial shelving, workshop benches, distribution equipment, and retail fixtures where reliable, straight-line movement is required.
Key Features
- Load Capacity 140kg per castor ? engineered for consistent performance under sustained heavy loads
- Wheel Diameter 125mm ? provides good ground clearance and rolls smoothly over minor floor irregularities
- Wheel Construction Blue rubber tread bonded to a black polypropylene centre ? reduces rolling noise and protects floor surfaces
- Bearing Type Ball journal bearing ? ensures low-friction, efficient rotation with minimal effort
- Tread Hardness 75 Shore A ? a balanced hardness that suits both smooth concrete and sealed timber floors
- Top Plate Finish Zinc-plated pressed steel ? provides resistance to light moisture and general workshop conditions
- Castor Type Fixed (non-swivel) ? maintains straight-line direction, ideal for paired use with swivel castors
- Tread Width 37.5mm ? broad contact area for stable load distribution
- Total Height 157mm ? consistent with standard castor height ranges for most trolley and bench frames

* The maximum load rating for a set of 4 castors is calculated at 75% of the combined individual ratings to account for uneven load distribution across all four mounting points.
Typical Applications
Warehousing & Logistics
Suitable for picking trolleys, packing benches, and goods-movement equipment operating on concrete or sealed floors.
Workshops & Manufacturing
Ideal for tool carts, assembly benches, and mobile workstations where straight-line tracking is important.
Distribution & Retail
Well suited to roll cages, display units, and storage racks that require controlled directional movement.
Shelving & Storage Systems
Compatible with mobile shelving bays and archive storage units where load stability and floor protection are priorities.
Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor is mounted in a set position and only rolls in a straight line, providing directional stability. A swivel castor rotates 360° to allow steering and changes of direction. For most trolleys and mobile platforms, a combination of two fixed castors at the rear and two swivel castors at the front is recommended for optimal control.
Is the 140kg load rating per castor or for a set of four?
The 140kg rating is per individual castor. When using a set of four castors, the practical maximum load for the set is 420kg ? calculated at 75% of the combined total to account for uneven weight distribution across all four mounting points during real-world use.
Will the blue rubber wheel mark or damage my floor?
The blue rubber tread at 75 Shore A hardness is formulated to be non-marking on most hard floor surfaces including sealed concrete, vinyl, and timber. It provides a degree of floor protection compared to harder plastic or cast iron wheels, making it a practical choice for environments where floor condition is a consideration.
What fixings are required to mount this castor?
This castor uses a 4-bolt top plate measuring 100mm x 85mm, with hole centres of 60mm x 80mm and a hole diameter of 10mm. Standard M10 bolts, washers, and locking nuts are required for installation. These are not supplied with the castor and should be sourced separately to suit your specific frame or platform thickness.
