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
Polyurethane tread · working temperature -30°C to +80°C
- Rolls quietly and smoothly
- Kind to most finished floors
- Hard-wearing, carries a high load for its size
- Ideal on concrete, epoxy, vinyl and tiles
- Not intended for very hot areas
- Less cushioning than rubber over rough ground
Details & FAQs
Heavy Duty Stainless Steel Fixed Castor
This heavy-duty 250mm stainless steel fixed castor runs on a large blue polyurethane on nylon wheel, carrying up to 550kg per castor. It is designed for demanding industrial environments where strength, durability and corrosion resistance are critical.
The wheel gives low rolling resistance and smooth movement under heavy loads, and the 87 Shore A tread balances durability, shock absorption and floor protection for indoor and outdoor use. The 135 x 110mm top plate has four 12mm holes, and the castor works from -30°C to +80°C.
Why Choose This Castor
- ✓ Corrosion-resistant stainless steel frame for wet, chemical or hygienic areas

- ✓ Ball bearing hub for smooth, quiet, efficient rolling
- ✓ Wide 50mm tread for stability and load support
- ✓ -30°C to +80°C temperature range
* Load capacity is per castor. For a set of four, allow for uneven floors by planning on three castors carrying the load.

Frequently Asked Questions
Does this castor swivel?
No. This is a fixed castor, so it rolls in a straight line. Pair it with swivel castors if your trolley needs to steer.
What is the wheel made of?
A blue polyurethane tread on a nylon centre, with an 87 Shore A hardness and a ball bearing hub.
How much weight can it carry?
Each castor is rated at 550kg. A set of four is best used for loads up to around 1650kg, allowing for uneven floors.
How is it fitted?
The 135 x 110mm top plate has four 12mm holes on 105 x 80mm centres. Bolt it flat to the underside of your trolley or equipment.
What temperatures can it be used in?
The castor is suited to temperatures from -30°C to +80°C, for chilled rooms or warm production floors. Its total height is 303mm.
