How to install threaded stem casters
Aug 05 , 2020
Threaded stem casters, as the name implies, are casters with threaded stem. The installation method is to connect the screw to the required object by rotating the screw to fix it to the object. Due to the limitation of force, threaded stem are usually used in light duty casters, medium duty casters and other furniture, non-heavy duty industrial appliances, medical equipments, etc.
Generally speaking, the larger the wheel size, the larger the threaded stem diameter, because the load-bearing capacity becomes larger. The length of the threaded stem is determined for the specific use situation. Threaded stem casters are usually also swivel/universal casters, and the wheels themselves can rotate 360degrees under unlimited conditions. Therefore, you cannot hold the caster to install it firmly.
To solve this problem, people invented a threaded stem with a nut. Therefore, you will find that there is usually a nut at the bottom of the threaded stem, which is completely integrated with the threaded stem, unless the threaded stem breaks, avoiding the embarrassment of slipping.
When installing threaded stem casters, we usually use a thin wrench to turn the nut counterclockwise until it can no longer be turned. The threaded stem is tightly combined with the installed object. Of course, some designs themselves are bolt-hole casters, and screw a screw directly from under the hole, which also needs to be tightened by a wrench. There are also designs where the bolt-hole has a locking position, and the screw does not have a nut, but it has a clip. By combining with the hole locking position, it can be fixed by rotating the entire caster.
Compared with top plate casters, threaded stem casters are more convenient to install, only need to screw a nut. However, there are disadvantages, the installation firmness will be smaller than the top plate casters, and the force capacity is also slightly weaker.
Threaded stem casters are mostly reflected in such application scenarios as furniture casters, medical casters, platform trolleys, and shopping carts.
