Swivel Castors
Swivel Castors and wheels can swivel 360 degrees about the vertical axis (see figure below). They consist of a housing and a caster wheel. The housing itself is made up of a plate fitting, swivel bearings and a yoke. The Yoke is often referred to as the castor's frame (see figure below).The plate fitting determines how the... castor is going to be attached to the equipment. It is usually either a single bolt hole fitting or a plate fixing which is generally square, rectangular or triangular. Plate fittings are usually bolted to equipment so knowing your required bolt hole centres is important. The Swivel Head consists of a ball race and a number of ball bearings that roll within it. Swivel Castors can either have a single ball race or a double ball race. They perform the same function. The double ball race was developed for medium and heavy applications. This is because they are compact, perform well under static and dynamic loads and provide excellent steerability.
Swivel castors can be fitting with locks which lock (brake) wither the wheel or the swivel head or both. See Brake Castors.
Swivel Castor Components
Swivel Castor Offset
The Swivel Castor's offset it the distance from the swivel axis to the centre of the wheel (where it is secured to the castor frame). It is the reason a swivel castor will go in the direction you want it to go regardless its starting direction. The offset and castor wheel's diameter make up the swivel radius where the swivel radius = Offset + (Wheel Diameter / 2).
This is the radius of circle described but the outer dimension of the wheel swivelling around the vertical axis. Basically, this is important because it tells you how much room is needed for the swivel caster to swivel. Furthermore, the general rule is the bigger the offset the better the castor's running performance but the lower the weight it can carry. Read More

Read More75mm Automated Guided Vehicle (AGV) Castor has a shock absorption 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 112mm x 112mm and has 4 bolt holes that are spaced 92mm x 92mm, each with a 9mm hole diameterThis 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. - In Stock

Load Capacity = 250kgNylon is a high quality, low maintenance, impact resistant wheel that has a high load capacity. The nylon material is extremely resistant to salts, greases, acids and alkalis and will not mark or damage concrete floors. This makes Nylon probably the most popular castor wheel material.The roller bearing in the hub (central part of the wheel) consists of steel rollers within an impact resistant plastic cage. These rollers rotate between the axle tube and the wheel hub which reduces the rolling resistance making it easy to move even under heavy loads. Roller bearings are rugged, robust and largely maintenance-free.
