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
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 Castor
This 305mm heavy duty swivel castor has a black pneumatic tyre on a pressed steel centre and a directional lock, rated at 550kg per castor. The air-filled tyre cushions heavy loads over rough and uneven ground, and the directional lock lets you switch the castor from free swivel to straight-line running whenever you need it.
Lock the swivel for straight runs down long aisles or yards, then release it to steer in tight spaces. A ball bearing keeps the wheel rolling smoothly, the 105mm tread spreads the load, and the castor fixes with a heavy 200 x 160mm top plate using four 14mm bolts.

Frequently Asked Questions
What does the directional lock do?
It locks the swivel head so the wheel runs in a straight line like a fixed castor. Release it to let the castor swivel freely again.
How much weight can it carry?
Each castor is rated at 550kg.
Does it have a wheel brake?
No. The lock only stops the swivel turning; it does not stop the wheel rolling.
How is it fitted?
The 200 x 160mm top plate has four 14mm holes on 160 x 120mm centres and bolts flat to the underside of your equipment.
How tall is the castor?
The total castor height is 358mm.
Does the tyre need air?
Yes. Keep the tyre correctly inflated for the best ride and full load capacity.
