Castor Uses

Castor applications can be divided into 2 main categories:

a) Castors for use on trucks, trolleys trailers etc, which are used as a means of transportation (ie. they are loaded with goods of some description and regularly moved from one place to another)

b) Castors fitted to a machine or other device to enable it to be delivered to the place where it is used or to enable it to be moved occasionally for very short distances

In the case of a) it is essential that castors should have the lowest tractive resistance and be able to swivel freely so that the trolley can be manoeuvred without too much effort. To achieve this, wheels should be at least 100mm in diameter and preferably 150mm diameter or more, regardless of the rated load capacity.

For category b) smaller castors may well be acceptable and are often used at their full rated capacity.
