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

The brake on this castor is a Total Stop Brake which is also known as a Swivel and Wheel Brake. This means that when the brake is applied, not only is the wheel braked but the swivel action is also locked.
A Polyurethane tyre offers a low tractive resistance making it easier to get moving compared with softer rubber tread wheels. It is also a bit softer than hard tread wheels making the castor smoother and quieter running. Polyurethane is also non-marking and gentle on floors. Put this wheel into a strong bracket that has a double ball race in the swivel head and you have a castor that is a great choice for the wide range of industrial and domestic applications.

There is a hardened Taper Roller Bearing in he swivel head, which has a grease nipple, for smooth swivelling action and durability. The Top Plate is 145mm x 145mm and has 4 bolt holes that are spaced 120mm x 120mm, each with a 11mm hole diameter.The castor is able to tilt +/- 5o from its central axis according to the flatness of the floor. This ensures that this castor's wheels keep contact with the floor allowing smooth AGV movement and protection of the loaded cargo when changing directions (See illustration below)The wheels are more widely separated from each other than most Twin Wheel Castors. When changing direction, the two wheels spin in opposite directions to each other which reduces the castor offset. The smaller the offset the less chance that the AGV will deviate from its designated line.This castor frame has two wheels with a Polyurethane tyre (Shore A 95) on an Aluminium centre each containing ball bearings, 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

There is a hardened Taper Roller Bearing in he swivel head, which has a grease nipple, for smooth swivelling action and durability.The castor is unique because it has a self-aligned function enabled by two swivelling axes each with different swivelling radii so that the castor's offset can automatically alter when changing direction to optimise the castor's turning circle for the AGV. Specifically, the offset can range from 10mm to 30mm which reduces the castors 'swing' enabling it to better follow the 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 diameter,This castor frame has two wheels with a Polyurethane tyre (Shore A 95) on an Aluminium centre each containing ball bearings, The polyurethane wheel has excellent elasticity the minimises slipping that can happen when an AGV starts or stops.
