Stem casters are used in a variety of applications. They are generally found in places that have limited space, such as hospitals, offices, and restaurants. These casters provide mobility for items that need to be moved, and they reduce the effort required to move these items. Having equipment mounted on casters can also help to prevent them from falling out of place.
How does caster affect alignment?
Various types of stem casters are available, and each one has its own features. For instance, there are threaded stem casters, and top plate model casters. The former has a threaded stem above the wheel housing, while the latter consists of a plate with four holes and a wheel. Which type you choose depends on your specific application and budget. However, both of these types offer superior mobility and are relatively easy to install. Source : https://www.castercity.com/stem-casters-by-stem-type/
Threaded stem casters work well in tight spaces. They allow for a lot of movement and are a great addition to any furniture. This type of caster is also easy to clean and replace.
Top plate model casters are a less expensive alternative to the threaded stem caster. But this type of caster isn’t as simple to replace, and it may not be suitable for all applications. Therefore, it’s best to consult with a professional before purchasing.
Grip ring stem casters are a good choice for smaller applications. They are designed to fit into tubing, so they compress to keep the caster in place. As they are pressed into the tubing, the brass ring on the stem expands to keep the caster in place.
