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 Moretor with 150m diameter wheels has shock absorbing function and a bracket made from strong Forged steel that is zinc plated. There is double thrust bearing in the swivel head to achieve a high load capacity and maintain castor performance and durability. The role of the spring in an AGV castor is different to that of a standard shock absorbing castor. In a standard shock absorbing castor, the spring absorbs shock and noise whereas, it's role in a AGV castor is primarily to keep the wheels in contact with the floor. When determining the overall height requirement of a shock absorbing AVG, it should be designed based on the spring cushion being fully compressed. The shock absorbing pad made from a special rubber compound absorbs minor shocks and vibrations to protect the AGV unit. There is a 10mm range of compression which helps prevent the castors from losing contact with the floor which may be caused by small floor imperfections. An AGV's castor leaving the floor when changing directions is often the cause of the AGV becoming unbalanced and coming to a stop by straying off its designated path. The Top Plate is 145mm x 145mm and has 4 bolt holes that are spaced 120mm x 120mm, each with a 11mm hole diameter This castor frame has two wheels with a Polyurethane tyre (Shore A 95) on an Aluminium centre each containing ball bearings, Having a twin wheel castor is great for reducing the effort required to swivel the castor and most efficient by reducing the amount of room the castor needs to turn the AGV Cart. The polyurethane wheel has excellent elasticity the minimises slipping that can happen when an AGV starts or stops. In addition, the elasticity also absorbs small shocks arising from small imperfections in the floor. The wheel itself is non marking and will not damage the floor. -
