# Design and Testing of a Measurement Device for High-Speed Bearing Evaluation
## 2 Materials and Methods  
Several existing studies point to the positive impact of using nanoparticles on high-speed bearings in terms of their performance. Significant results have been obtained by various researchers at different times. [PERSON] in 2015 discovered that adding nanoparticles to the lubricating oil leads to increased viscosity, improved friction coefficient, and better pressure distribution, subsequently increasing the load-bearing capacity of sliding bearings. These findings demonstrate the potential for a significant improvement in bearing performance when using nanoparticulate lubricants [21].  
[PERSON], in 2014, focused on the development of nanocomposites for self-lubricating bearings and achieved success by using solid lubricating nanoparticles to reduce friction. His work opened the path to utilizing modern materials and technologies to create self-maintaining bearings that reduce friction [22].  
[PERSON] in 2015 proposed a revolutionary approach to creating nano-bearings through physical adsorption by confining the oil to a solid surface. This innovative method demonstrated a significant load-bearing capacity in thin lubricating film layers, offering new possibilities for effective solutions in high-speed and low-friction applications [23].  
[PERSON] in 1995 engaged in simulations of various graphite bearing models and explored their frictional properties. His work emphasized the potential of molecular bearings in nanodevices and their ability to carry loads, which is crucial in microscopic technology [24].  
Overall, these studies provide evidence that the incorporation of nanoparticles into high-speed bearings can significantly enhance lubrication efficiency, reduce friction, and improve the properties of these bearings.  
To gain deeper and relevant insights into the impact of nanoparticle additives on the physical properties of rolling bearings, an experiment on a specific type of bearing--TX7206 D36--was conducted (Figure 1). We pressed two pieces of non-dismantlable bearings onto the shaft and these bearings are known for their ability to operate at high speeds, which is significant in various industries. One of the industries where these bearings are found is the textile industry, specifically in rotor spinning machines [25].  
Rolling bearings are a crucial component in textile machines, and their development is closely linked to finding the best ways to store and utilize the most critical components in textile machines. Their use, however, is not limited to just textile machines, as they find applications in instrument technology where the properties offered by these bearings are required. As seen in Figure 2, special double-row ball bearings designed for textile machinery are engineered and dimensioned to withstand the high rotational frequencies commonly found in the textile industry. They are known for their high dimensional precision and reliable operation. These characteristics ensure their significant utility of using rolling bearings in these applications.  
Performing experiments on these specific bearings can provide crucial insights into how nano-particle additives affect their performance and longevity. These findings can have significant implications for improving the efficiency and reliability of rolling bearings in industrial applications, where high speeds and precision are critical for achieving optimal results. Understanding how nano-particle additives influence the performance of such bearings can lead to advancements in their design and maintenance, potentially extending their lifespan and reducing maintenance costs, all of which are essential in industries relying on high-speed and high-precision machinery.
