In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”
- Spherical Roller Bearings: Spherical roller bearings are designed to accommodate heavy radial and axial loads, as well as misalignment and shaft deflection. They are commonly used in applications where high load capacity and the ability to compensate for misalignment are essential, such as in heavy machinery, mining equipment, and industrial gearboxes.

- Spherical Roller Bearings: Spherical roller bearings are designed to support heavy radial loads, as well as moderate axial loads, and are capable of accommodating misalignment. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.
