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.
Floors & use
Rubber tread
- Cushions the load and soaks up vibration
- Quiet on most surfaces
- Copes with uneven floors, thresholds and outdoor use
- Good grip on smooth floors
- Takes more effort to push than nylon under heavy loads
- Oils and solvents shorten tyre life
Details & FAQs
This 125mm swivel castor features a blue rubber tread bonded to a black polypropylene wheel, mounted on a zinc-plated pressed steel top plate with a built-in directional brake. Engineered for demanding commercial and industrial environments, it delivers smooth, controlled mobility across hard and semi-hard floor surfaces — making it the preferred choice for trolleys, service carts, workshop benches, display units, and light industrial equipment requiring a maximum load capacity of 140 kg per castor.
- Wheel Diameter: 125 mm — provides efficient rolling momentum and stable load distribution over varied surfaces.
- Load Capacity: 140 kg per castor (420 kg across a set of four) — suited to heavy-duty trolleys and mobile workstations.
- Blue Rubber on Polypropylene Wheel: The rubber tread (75 Shore A hardness) absorbs vibration and protects floor surfaces, while the polypropylene core keeps overall weight low.
- Ball Journal Bearing: Delivers consistently smooth swivel rotation with minimal rolling resistance, reducing operator effort.
- Directional Brake: A foot-operated brake locks both the wheel rotation and the swivel action simultaneously, securing equipment in position on inclines or during loading operations.
- Zinc-Plated Pressed Steel Top Plate: Corrosion-resistant finish suitable for damp or humid working environments.
- 4-Bolt-Hole Fixing: Standard dual hole-centre pattern (60 mm and 80 mm) ensures broad compatibility with existing equipment frames.
- Total Castor Height: 157 mm — consistent with standard equipment clearance requirements.
What does a directional brake do, and how is it operated?
A directional brake locks both the wheel rotation and the swivel head at the same time, preventing the castor from rolling or turning in any direction. It is engaged and released by pressing the foot-operated lever with your foot — no tools required. This makes it ideal for situations where equipment must remain stationary during loading, unloading, or use on a slight incline.
Is this castor suitable for use on hard floors such as concrete, vinyl, or ceramic tiles?
Yes. The blue rubber tread at 75 Shore A hardness provides sufficient grip and vibration absorption for smooth and semi-smooth hard floor surfaces including concrete, vinyl, epoxy-coated floors, and ceramic tiles. The rubber compound also helps protect floor finishes from marking or scuffing under normal operating loads.
How do I know if this castor will fit my existing equipment?
This castor uses a standard 4-bolt top plate measuring 100 mm (length) x 85 mm (width), with fixing hole centres of 60 mm and 80 mm and a hole diameter of 10 mm. Before ordering, measure the existing top plate on your equipment and compare these dimensions. The dual hole-centre pattern (60/80 mm) provides compatibility with a wide range of standard trolley and equipment frames.
Can I use a single castor rated at 140 kg to carry a 140 kg load?
No. The 140 kg figure is the rated capacity for a single castor under ideal, evenly distributed static conditions. In practice, load is rarely distributed perfectly equally across all four castors. As a general guideline, the combined rated capacity of all four castors should be at least three times the total load weight. For this castor, a set of four provides a combined rating of 420 kg, making it appropriate for equipment with a total loaded weight of up to approximately 140 kg.
