No acute effects of nano-sized TiO2 were observed in Danio rerio (zebrafish) embryos. Exposure of rainbow trout to TiO2 NPs triggered lipid peroxidation, influence on the respiratory tract, disturbance in the metabolism of Cu and Zn, induction of intestinal erosion and accumulation in kidney tissue. Linhua et al. exposed juvenile carp to 100 and 200 mg/ml of particles and TiO2 observed no mortality. However, the fish suffered from oxidative stress and pathological changes in gill and liver. In the infaunal species Arenicola marina, exposure to TiO2 NPs in sediment caused sub-lethal effects including decrease in casting rate and increase in cellular and DNA damage. Aggregated particles were visible in the lumen of the gut, but no uptake through the gut or the skin was observed.
With fewer components compared to other bearing types, they are relatively easy to install and maintain With fewer components compared to other bearing types, they are relatively easy to install and maintainwhat is a thrust ball bearing. However, it's important to note that they are not suitable for applications involving radial loads, as they would wear out quickly under such conditions. For these scenarios, radial ball bearings or roller bearings would be more appropriate.
The bearings have a self-aligning feature that compensates for misalignment, reducing wear and tear The bearings have a self-aligning feature that compensates for misalignment, reducing wear and tearbearing nu 316. They also have a sealed design that prevents contaminants from entering the bearing and extending its life. As a result, maintenance costs are reduced, and downtime is minimized.

- Ball Bearing: Ball bearings, including deep groove ball bearings, utilize spherical balls as rolling elements that move between inner and outer raceways. They are primarily designed to support radial loads, with some designs capable of handling limited axial loads. Ball bearings are commonly used in applications where smooth and efficient rotation is required, such as in electric motors, pumps, and gearboxes.
