How to Choose the Right Sealey Castor Wheels
Choose castors by load, wheel diameter, mounting style and the way the equipment needs to move — then confirm the dimensions before ordering.
Load + mounting + movement
Those three checks narrow the choice quickly and help avoid a castor that fits the load but not the equipment.
Calculate the working load
Consider the weight of the equipment plus its maximum contents, then allow a sensible safety margin.
Choose the wheel diameter
Larger wheels generally roll more easily over small surface irregularities, but available height and clearance matter.
Match the mounting
Confirm whether you need a bolt-hole or plate mounting and check all relevant fixing dimensions.
Choose movement & braking
Use fixed castors for directional stability, swivel castors for manoeuvrability and locking versions where restraint is required.
The four decisions that matter most
A castor wheel has to carry the load, physically fit the equipment, provide the required manoeuvrability and work on the intended floor. Matching only the wheel diameter is not enough.
Information to check before ordering
- Total equipment weight when fully loaded
- Number of castors sharing the load
- Wheel diameter and overall height
- Bolt-hole or plate mounting dimensions
- Fixed, swivel or total-lock requirement
- Floor surface and operating environment
Avoid the expensive shortcut
Similar-looking products are not automatically interchangeable. Use the product reference and application information together rather than selecting from appearance alone.
Choose by the job, not just the product name
These broad groups explain the main differences to think about before you jump into the product directory.
Swivel castors
Allow the equipment to change direction easily and are commonly used where manoeuvrability is the priority.
Fixed castors
Track in a straight direction and can be combined with swivel castors to give controlled steering.
Total-lock castors
Locking designs can restrain wheel rotation and/or swivel movement depending on the product. Check the exact locking function before ordering.

Quick answers before you choose
How do I work out the load per castor?
Start with the maximum loaded weight and divide it across the castors expected to carry the load, then include a suitable safety allowance for uneven floors and dynamic loads.
Bolt-hole or plate mount?
Match the mounting already used on the equipment and confirm the dimensions. They are not automatically interchangeable.
Are larger castor wheels always better?
Not always. They can improve rolling performance, but overall height, mounting space, load rating and equipment geometry must also be suitable.
