125mm Pressed Steel Swivel Castor with Blue Rubber on Polypropylene Wheel - 140kg Max Load

What surfaces is this castor suitable for?

The blue rubber tread is designed for use on smooth to semi-smooth hard floors, including concrete, tile, vinyl, laminate, and sealed timber. The 75 Shore A hardness provides a balance between grip and rolling resistance, making it appropriate for both indoor and sheltered outdoor environments. It is not recommended for deeply uneven or heavily abrasive surfaces.

How is this castor mounted, and what fixings are required?

This castor uses a 4-bolt-hole top plate for mounting. The plate measures 100mm x 85mm with fixing centres of 80mm x 60mm and 9mm diameter bolt holes. Standard M8 bolts are typically used, though the appropriate fixing hardware should be selected based on the thickness and material of the mounting surface. No stem or socket fitting is required for this model.

What is the maximum load this castor can support?

Each individual castor is rated to a maximum load of 140kg under normal operating conditions on a flat, even surface. When fitting a set of four castors, the combined rated capacity is 560kg, though it is standard practice to calculate load distribution conservatively ? particularly for uneven loads or dynamic movement ? and to allow an appropriate safety margin.

Is a braked version of this castor available?

Yes. A braked variant of this castor is available separately. The brake mechanism locks the wheel to prevent unintended movement, which is particularly useful in static work environments, on inclines, or where equipment must remain stationary during use. Please refer to the braked castor listing for full specifications and compatibility details.
