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

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 15mm to 35mm which reduces the castors 'swing' enabling it to better follow the 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, 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

Because of the lifting and lowering function of the Foot Master castor, like all Jacking Castors, it is important understand that each castor may be subjected to HALF THE TOTAL WEIGHT. Therefore, the recommended load capacity for each Foot Master Levelling Castor is half the castor's Static Load Capacity, that is, when the castors' levelling function is not being used. The load capacity of the Footmaster Castor when it is being moved and positioned is given by the Dynamic Load Capacity.
This 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 with added stability using the levelling and anti-vibration features.
