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
Stainless Steel Bolt Hole Castor
This 80mm stainless steel swivel castor runs on a grey electrically conductive rubber wheel and carries up to 50kg per castor. It suits medical equipment, laboratory trolleys and pharmaceutical manufacturing, where static discharge has to be managed.
The A85 tread balances grip with durability, and the ball bearing helps the castor move smoothly. A single 12mm bolt hole fits into the end of a tube leg or onto a threaded fixing, which keeps installation and maintenance simple.
Why Choose This Castor
- ✓ Electrically conductive rubber wheel to help manage static discharge
- ✓ Stainless steel housing for washdown areas
- ✓ A85 tread hardness for a balance of grip and durability
- ✓ Ball bearing for smooth movement
- ✓ 50kg load capacity per castor
- ✓ Single 12mm bolt hole for tube legs and threaded fixings
* 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
- ✓ Medical equipment such as hospital beds and medical carts
- ✓ Laboratory trolleys where static control is essential
- ✓ Pharmaceutical manufacturing with controlled electrostatic conditions
Tube Adaptors Also Available
Fitting this castor to a round or square tube leg? Matching tube adaptors are also available. Choose the size that fits the inside of your tube and buy it together with your castors.
Frequently Asked Questions
What is the conductive wheel for?
The electrically conductive rubber helps manage static discharge, which suits medical, laboratory and pharmaceutical areas where static has to be controlled.
How much weight can it carry?
Each castor is rated at 50kg. A set of four is best used for loads up to around 150kg, allowing for uneven floors.
How is it fitted?
It has a single 12mm bolt hole. Fit it with a matching 12mm bolt or threaded stem, or use a matching tube adaptor to fit it into a round or square tube leg.
What temperatures can it work in?
The castor works from -20°C to +60°C.
How tall is the castor?
The total castor height is 109mm and it needs 70mm of clearance to swivel freely.
