Swivel castor wheels enable the movement of objects in any direction. Unlike fixed castors, swivel castors have a freedom of motion to move omnidirectional and can be used across a range of Industrial, Manufacturing and Commercial sectors. Made up of a wheel with a housing mounted on a bearing configuration under either a mounting plate or a column/tube, swivel castor wheels can be used in large and small-scale applications from carts and trolleys up to larger applications such as hospital beds.
Understanding the weight you want your castors to support is vital to your choice of castor. Choosing the correct castor type either Top plate, bolt hole or threaded stem depends on how you want to fix your castor to your application and how much weight each castor is expected to carry.
There are 3 different castor wheel ratings depending upon the strength, durability and manoeuvrability required for the load capacity. These are Light duty, supporting weights of up to 75 kg, Medium duty supporting weights of between 76 kg and 140 kg and heavy-duty supporting weights of over 141 kg.
Castors are available in different sizes and support different load capacities. The wheels are made from different materials such as steel, polypropylene and rubber and can be non-marking.
The measurement of a castor is really important and will be the difference between it working and not working. Measure the height and width of both the Top Plate and Bolt Hole Pattern, measuring from the centre of one hole to the other. Measure the wheel size over the centre when the wheel is lying flat.
