From the market, you can find so many styles of casters, but in general, all styles of casters can be categorized into two types:
This style of casters can move in any direction, which makes the equipment on them moves very easy to anywhere, even if the load is very heavy. Swivel casters are very popular to use for desks, tables, beds, and so on.
Different from the swivel casters, the rigid casters can not change their direction when moving. Rigid casters are very durable, they only move in a straight line is a partial reason. Compare with the swivel casters, based on the same load, people usually think they can work longer.
Casters Classification By Braking Ability
Braking ability is an important factor of a caster. For different designs of the casters, we can find different braking ways as below:
Brakes that press against the side of the wheel
Brakes that press against the tread of the wheel
Brakes that push against the floor (called floor brakes)
for the Swivel caster, there are two parts of the braking, one is to stop the wheel, and one is to stop it from rotating. People usually call the caster a total lock brake caster if the user is able to lock both the swivel abilities of the castor and the wheel movement.
Casters Classification By Weight of Load
Light-duty casters: about 20Kg – 100Kg.
Used in light equipment such as computers or laundry equipment.
Medium duty casters: about 80Kg – 150Kg.
