Industrial knobs are often categorized according to the material from which they are made. Aluminum knobs are made of aluminum, whereas plastic knobs are made of plastic. There are also industrial knobs made of phenol-based compounds, such as phenolic ball knobs.
Phenolic ball knobs are commonly used to adjust machinery. They have up-down, as well as right-left, directional movement. While other types of industrial knobs offer similar movement, though, phenolic ball knobs stand out with their unique composition. They are made of phenol resin with reinforcing fillers. Below are some of the top benefits of phenolic ball knobs.
Ergonomic
Phenolic ball knobs are ergonomic. They have a round shape that’s easy to grip. There are no jagged or sharp edges. Rather, phenolic ball knobs are entirely smooth. Whether you’re performing up-down or right-left directional movement, you can comfortably use a phenolic ball knob for long periods thanks to their naturally ergonomic design.
Heat Resistant
If you’re looking for an industrial knob that holds up well in hot environments, a phenolic ball knob is the way to go. They are very heat resistant. Most traditional thermoplastics will warp or melt when exposed to excessively hot temperatures. Phenolic, on the other hand, will maintain its physical characteristics. They will retain shape and strength even when ambient temperatures rise.
Lightweight
Phenolic ball knobs are lightweight. Phenolic weighs less than aluminum, brass, steel and other metals and alloys. Lighter controls reduce inertia while allowing for more precise feedback during adjustments.
Strong
Don’t let their lightweight properties fool you into thinking phenolic ball knobs are weak. Phenolic is a strong material that can withstand a great deal of external force and mechanical stress. Some phenolic compounds have a tensile strength of 10,000 pounds per square inch (PSI), whereas others have a tensile strength of 20,000 PSI. Regardless, phenolic ball knobs are strong and durable.
Chemical Resistant
Another benefit of phenolic ball knobs is chemical resistance. Unlike many other materials, phenolic can resist a variety of chemicals, including oil, coolant and solvents. Their chemical-resistant properties make phenolic ball knobs a popular choice for factories and workshops. Even when exposed to chemicals, they won’t swell, crack or otherwise degrade.
In Conclusion
Phenolic ball knobs offer a rare balance of comfort, durability and performance. Their ergonomic shape supports long periods of use without strain. Their ability to withstand heat, chemicals and mechanical stress makes them reliable in demanding industrial settings. Add in their lightweight design and long service life, and it becomes clear why phenolic ball knobs remain a trusted choice.
