125mm Swivel Castor With Blue Rubber on Polypropylene Wheel, Directional Brake - 140kg Max Load

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.
