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

For the compression performance, please see the image for the curve by clicking on the thumbnail image above. To use this curve, please calculate the weight being carried by this castor and divide that by the one less than the number of castors on your equipment, So if you have a trolley using 4 of these castors and the total weight being carried is 500kg, then the compression of the rubber pad is the reading given on the y axis at 167kg (500kg / 3 = 167kg) which is between 11 and 12mm.

This allows users to move and position large equipment into place with added stability using the levelling feature.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 levelled is given by the Dynamic Load Capacity. - In Stock
