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
Pneumatic tyre
- Rides over gravel, grass and rough ground
- Maximum cushioning for fragile loads
- Can puncture; check tyre pressure
- Lower load rating than a solid wheel of the same size
Details & FAQs
Heavy Duty Pneumatic Castors
This 300mm heavy duty swivel 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 450kg per castor and is built for heavy duty baggage trolleys, runway equipment and general heavy duty work.
The housing is welded steel with a zinc plated finish, a strong welded central kingpin and a bolted wheel axle. The pneumatic tyre is steel wire reinforced for a hard-wearing ride, and the swivel head runs on an axial grooved ball bearing with a tapered roller bearing, making it dust and splash-proof. A grease fitting makes routine greasing easy. It bolts on with a 200 x 160mm top plate and stands 355mm tall.

Frequently Asked Questions
Does this castor swivel?
Yes. It is a swivel castor, so it turns freely to steer your trolley. The swivel head runs on an axial grooved ball bearing and a tapered roller bearing.
What is a pneumatic wheel?
It has an air-filled rubber tyre on a pressed steel centre. The air cushions the load, and this tyre is steel wire reinforced so it stays hard-wearing on rough ground.
How much weight can it carry?
Each castor is rated at 450kg with the tyre correctly inflated.
Can I use it outdoors?
Yes. The swivel head is dust and splash-proof and the pneumatic tyre rolls smoothly over rough and uneven ground, so it suits outdoor and runway use.
How do I maintain it?
Use the grease fitting to grease the castor regularly and keep the tyre at the correct pressure.
How is it fitted and how tall is it?
It has a 200 x 160mm top plate with 14mm holes on 160 x 120mm centres, bolted flat to the underside of your trolley or equipment. The total castor height is 355mm.
