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.

- Rides over gravel, grass and rough ground

Details & FAQs
Heavy Duty Pneumatic Castors
This 420mm heavy duty fixed castor runs on a large black pneumatic rubber wheel on a pressed steel centre, giving a smooth, cushioned ride over rough and uneven ground. It carries 750kg per castor and is built for warehouse trolleys, outdoor carts and construction equipment.
The fixed bracket keeps the wheel running straight for stable tracking, and the ball bearing reduces friction for smooth rotation. The pneumatic tyre gives cushioned movement over rough terrain, while the 115mm tread provides a stable contact area with the ground. It bolts on with a 200 x 160mm top plate and stands 480mm tall.
