Scroller roller wheels, specifically the Rolamite design, were invented in the mid-1960s and are purportedly used in applications such as airbags and nuclear weapon triggers. However, there is a significant lack of technical information available regarding their performance metrics, such as load capacities, speeds, and temperature tolerances, which are typically provided by bearing manufacturers. The discussion highlights skepticism about the claims made by manufacturers regarding the superiority of scroller roller wheels over traditional bearings, emphasizing the need for more detailed specifications to validate their use.
PREREQUISITESMechanical engineers, product designers, and anyone involved in the development or optimization of bearing systems will benefit from this discussion.
The Rolamite is now used in airbags and as the safety for the trigger in nuclear weapons.
It's not that I think they're being dishonest, but they are purposely not providing some information. Look at any bearing manufacturer. They will break down capacities based on materials, sizes, etc...These folks could do the same thing but they don't. I find that somewhat surprising.SkepticJ said:I do wonder if the reason for that isn't that they're being dishonest/overhyping it, but because they could be made of any number of materials, which would highly effect what loads, speeds and temperatures they could handle.
