Selecting Heavy Duty Castors
Choosing the Correct Castor for Heavy Loads & Industrial Applications
Heavy-duty castors are designed for applications where standard industrial castors may not provide enough load capacity, durability or long-term reliability.
They are commonly used on:
- Warehouse trolleys
- Industrial carts
- Machinery
- Fabrication equipment
- Mobile workbenches
- Production handling systems
- Heavy-duty transport platforms
Selecting the correct heavy-duty castor is important because higher loads place increased stress on the wheel, swivel head, bearings, mounting plate and castor bracket.
The operating environment, floor condition and frequency of movement should all be considered alongside load capacity.

What Is Considered a Heavy Duty Castor?
There is no universal definition of a “heavy-duty” castor. The term is generally used for castors designed for higher industrial load capacities and more demanding operating conditions.
Heavy-duty castors typically feature:
- Reinforced steel brackets
- Larger wheel diameters
- Higher-capacity bearings
- Stronger swivel heads
Applications involving continuous movement, shock loading, rough floors or high static loads may require heavy-duty castors even where the load weight is relatively moderate.
Pressed Steel vs Fabricated Steel Castors
One of the most important differences between industrial castors is the type of bracket construction.
Pressed steel castors are generally suitable for medium and heavy-duty handling applications where strength, manoeuvrability and cost-effectiveness are important.
Fabricated steel castors are designed for higher loads, harsher environments and more demanding industrial applications.
Pressed Steel Castors
Pressed steel castors are manufactured using formed steel sections pressed into shape.
They are commonly used for:
- Medium and heavy-duty industrial applications
- Warehouse handling equipment
- Platform trucks
- General industrial mobility
Pressed steel castors provide:
- Good strength-to-weight performance
- Smooth manoeuvrability
- Cost-effective handling performance
Higher-quality pressed steel castors often feature thicker steel sections, reinforced swivel heads and double ball race bearings to improve durability and load performance.
Fabricated Steel Castors
Fabricated steel castors use welded steel construction and heavier structural components to achieve increased strength and higher load capacities.
They are commonly used on:
- Heavy machinery
- Steel fabrication equipment
- Industrial transport systems
- Engineering applications
- Severe-duty handling equipment
Fabricated castors are particularly suitable where castors are subjected to:
- Very high loads
- Severe impacts
- Continuous operation
- Demanding industrial environments
Many fabricated steel castors incorporate reinforced swivel heads, thrust bearings, taper roller bearings and heavy gauge steel components to improve performance under heavy loads.
Fabricated steel castors generally provide:
- Increased structural strength
- Improved rigidity
- Higher load capacities
- Long service life in demanding applications
They are typically heavier, larger and more expensive than pressed steel alternatives, but are often the better choice where load, impact or operating conditions are more severe.
GXT Extra Heavy Duty Castors
The GXT range is designed for extreme heavy-duty industrial applications where standard fabricated castors may not provide sufficient strength, durability or long-term performance.
These castors are engineered for applications involving:
- Very high loads
- Continuous industrial movement
- Power towing applications
- Heavy machinery
- Steel fabrication equipment
- Automated handling systems
- Industrial transport platforms
GXT castors feature extra-heavy-duty fabricated steel brackets with welded construction, reinforced swivel heads and precision bearing systems designed for demanding industrial environments. The fabricated steel frames are powder coated to provide additional protection against corrosion and industrial wear.
Many models incorporate:
- Thrust bearings and taper roller bearings in the swivel head
- Integrated heavy-duty axle shaft systems
- Twin ball bearing wheel hubs
- Powder-coated fabricated steel frames
- Power towing capability
The GXT range is available with several wheel options including:
- Machine cast nylon wheels
- Polyurethane tyre wheels
- Heavy-duty industrial wheel configurations
Depending on the model selected, individual castor load capacities range from approximately 900kg to over 6000kg per castor.
GXT castors are particularly suitable where:
- Maximum structural strength is required
- Shock loading is present
- Long service life is critical
- Equipment operates continuously under heavy loads
- Precise and reliable movement is important
Compared to standard fabricated castors, the GXT range provides:
- Higher load capacities
- Improved swivel performance under heavy loads
- Greater durability in harsh industrial environments
- Reduced rolling resistance
- Excellent long-term reliability
These castors are commonly used in heavy engineering, manufacturing, automated handling systems, aerospace applications, steel processing and industrial transport equipment where performance cannot be compromised.
