Swivel Castors
Swivel castors provide 360-degree movement for trolleys, workbenches, transport platforms, machinery and material handling equipment. Keystone supplies a wide range of options, including top plate and bolt-hole fixings, bra...ked models, stainless steel designs and heavy-duty wheels for industrial, commercial and specialist applications.How Swivel Castors Work
The swivel head contains ball bearings that allow the castor to rotate smoothly. Swivel castors may use either a single ball race or a double ball race. Double ball race swivel castors are often used for medium duty and heavy duty applications because they provide good steerability, compact construction and reliable performance under static and moving loads.
Swivel Castor Fixing Types
The fixing determines how the castor attaches to your equipment. Common swivel castor fixing types include: Top plate fixing – usually square, rectangular or triangular and bolted directly to the equipment. Single bolt-hole fixing – fitted using a central bolt or stem connection. When choosing a plate-fixing swivel castor, check the plate size, bolt-hole diameter and fixing centres to make sure it matches your equipment.
Braked Swivel Castors
Swivel castors can be supplied with brake options to improve safety and control. Depending on the castor, the brake may lock the wheel, the swivel head or both. For options with integrated brakes, view our braked castors.
Swivel Castor Components
The diagram below shows the main parts of a swivel castor, including the fixing, swivel head, yoke and wheel. Swivel castor components diagram showing fixing, swivel head, yoke and wheel
Swivel Castor Offset
The swivel castor offset is the distance between the swivel axis and the centre of the wheel. This offset allows the castor to trail behind the swivel point and turn in the direction of movement. The offset and wheel diameter determine the swivel radius: Swivel radius = offset + wheel diameter ÷ 2 This measurement shows how much space the castor needs to rotate fully around the vertical axis. In general, a larger offset improves running performance and steering, but may reduce the castor’s load capacity.
Choosing the Right Swivel Castor
Use the filters on this page to compare swivel castors by wheel diameter, load capacity, fixing type, brake option, wheel material and bearing type. If you are unsure which castor is suitable for your application, contact Keystone for technical advice. Read More

Read More plate and stainless casting frame, M12 x 18mm Threaded Stem Fitting. 280kg Static and 140kg Dynamic Load Capacity with Machine Cast Nylon Wheel and Vibration Damping Rubber Pad. Nylon Handwheel height adjustment Operation. This footmaster castor has an overall height of 82mm when the wheel is engaged with a total lift of 15mm using the rubber footpad. The version of the Footmaster Levelling castor has a double ball bearing with hardened stainless steel bearings in the swivel head. The KSGDN Footmaster castor has completely corrosion-resistant components applied. The Footmaster levelling castor is a multi-functional swivel castor that provides mobility, levelling and anti-vibration functions. This allows users to move and position large equipment into place. Because of the lifting and lowering function of the Footmaster castor, like regular Jacking Castors, it is important understand that each castor may be subjected to HALF THE TOTAL WEIGHT. Therefore, the recommended load for each Footmaster Castor is half the castor's Static Load Capacity of when the castor is stationary and the foot-pads are lowered. This load capacity of the Footmaster Castor when being moved and positioned is given by the Dynamic Load Capacity. -
