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
Rubber tread · working temperature -20°C to +60°C
- Cushions the load and soaks up vibration
- Quiet on most surfaces
- Copes with uneven floors, thresholds and outdoor use
- Good grip on smooth floors
- Takes more effort to push than nylon under heavy loads
- Oils and solvents shorten tyre life
Details & FAQs
Bolt Hole Stainless Steel Castors
This 100mm stainless steel swivel castor has an electrically conductive rubber wheel, made for healthcare settings where static electricity must be managed. The tread balances grip and durability, and the castor carries 80kg.
A ball journal bearing reduces friction for smooth changes of direction, and the castor fits through a single 12mm bolt hole in the centre of the swivel head.
Why Choose This Castor
- ✓ Electrically conductive rubber wheel to help manage static electricity.
- ✓ Stainless steel housing for clean indoor environments.
- ✓ Ball journal bearing that reduces friction.
- ✓ Grey tread 30mm wide and 85 Shore A.
- ✓ Single 12mm bolt hole in the centre of the swivel head.
- ✓ 80kg load capacity per castor.
* Load capacity is per castor. For a set of four, allow for uneven floors by planning on three castors carrying the load.
Where It Works Best
- ✓ Healthcare equipment: medical carts and trolleys where static control is essential.
- ✓ Laboratory settings: equipment that needs mobility and static discharge management.
- ✓ Electronics manufacturing: environments sensitive to static electricity.
Frequently Asked Questions
Does this castor have a brake?
No. This is a swivel castor without a brake, so it can change direction freely.
Why choose an electrically conductive wheel?
It helps manage static electricity, which matters on medical carts, in laboratories and in electronics manufacturing.
How much weight can a set of four carry?
Each castor is rated for 80kg. Planning on three castors carrying the load, a set of four suits about 240kg.
How is the castor fitted?
It fits with a single bolt through the 12mm hole in the centre of the swivel head. The bolt must match the 12mm hole size.
How much space does it need to swivel?
The swivel radius is 92mm and the total castor height is 134mm.
Where can I use this castor?
It suits medical carts and trolleys, laboratory equipment, and electronics manufacturing.
