Caster wheels with a stem are a great way to get the mobility you want from your equipment. You can choose between threaded, top plate, grip ring, or expandable rubber stems. Each of these types can have different uses, but each one is useful for a specific application. For example, threaded stem casters are best for a tight space. Top plate casters are better for a wider area. Grip ring stems have a small friction ring to keep the stem in place. Read more : https://www.castercity.com/stem-casters-by-stem-type/
Did the Chinese invent wheels?
Threaded stems can be purchased in 1/16” increments. These casters can be installed and removed without much trouble. They can be mounted via bolts or cross drilled mounting holes.
Threaded stem casters are also easy to clean and replace, and the stem is lubricated. However, threaded stem casters can become clogged with loose debris. Consequently, the caster might not move as smoothly as you’d like. This is particularly common in applications where a large amount of movement is needed.
The most common caster, in terms of both functionality and design, is the thermoplastic rubber wheel. Compared to steel, these wheels offer slightly lower weight capacity, but they roll smoothly and are great for absorbing shock. In addition, they are durable and resistant to chemicals.
Another type of caster, the top plate model, is a popular choice because of its swivel capabilities. It is typically a rectangular, square, or rectangular-square shaped caster. A top plate is a sturdy piece of metal that is usually screwed or welded in.
