Castors and wheels are now everywhere on the vehicles, planes, machines, trains, equipment, various machinery, and if you look down, then you will find them on the office chairs too. These are the components that people have never spent much time thinking about. Because of this versatility, these applications have become an important part of our every day life.
Well, these applications are considered as one of the most important development that have ever made. The castors are simply wheels and these applications are used generally in the metal housing, for easing the attachment for the machinery and equipment as well. If anyone decides not to use the castor housing wheels, then the wheels need to be attached via an axel and that will be fixed directionally.
In this context, an example can be given of a cart. You can imagine a cart having the wheels on an axel, in such situation, the movement will be restricted on a particular direction that can be on the forward or backward. If anyone tries to move the cart on the different direction, then they have to take a very wide turning circle.
The swiveling castor generally helps in such situation by enabling the wheel to move in a 360 degree direction without being restricted to any fixed direction. The invention of this swiveling industrial castors was simple, but the revolution it has brought within the industry is remarkable. The castor housing is essentially a mini axel and is housed within a metal casing.
The metal casing has a ball bearing head and that has either a square top plate for the fixing or has a bolt hole fixing. There are total four bolt holes on the top plate fixing castors attached on the underside of the trolley or on the machinery which is supposed to be moved. These applications are known to be one of the most common type of castors and these allow the loads to spread evenly.
On the other hand, bolt hole castors have a single bolt fixing and this is able to carry less weight comparatively. All of these castors can be fixed along with a locking mechanism that helps to make braked industrial castors. However, there are also some castors available that are known fixed castors and these applications are used for the industries who look for uni directional service.
It is true that there are too many choices to make for the professionals with these industrial castors. On the comparison scale, there are two which are extremes. If you get four swiveling castors fixed on the shopping trolleys, then this will surely make the trolleys uncontrollable as that will be moving in all directions and eventually will be very hard to manage.
Fortunately, there are variety of castors and those depend upon the specifications of service you have and want them to be fixed accordingly. Castors are available in a wide array of size and design and you are free to choose the one you are in need of.
