Moreover, heavy machinery, such as excavators and loaders, employs these oil seals to protect hydraulic systems and ensure efficient operation. Given the rigorous conditions these machines operate under, high-quality oil seals are imperative to prevent costly downtime and repairs.

Hydraulic ram pumps are versatile and can be used in various applications, including

Oil seals, also known as rotary shaft seals or lip seals, serve the primary function of sealing the rotating shafts in mechanical systems. They are typically made from elastomers, metals, or a combination of both, offering good resistance to various fluids, including oils, greases, and water. The 50x90x10 oil seal, with its dimensions indicating a 50mm inner diameter, 90mm outer diameter, and a width of 10mm, is designed to fit specific shaft sizes while providing optimal sealing performance.

Before beginning any maintenance work, ensure the system is depressurized and disconnected from any power sources. Wear appropriate personal protective equipment (PPE) to protect against high-pressure fluid and contaminants.

As mentioned above, these oxide NPs are harmful in part because both anatase and rutile forms are semiconductors and produce ROS. Particularly, P25 kind has band-gap energies estimated of 3.2 and 3.0 eV, equivalent to radiation wavelengths of approximately 388 and 414 nm, respectively. Irradiation at these wavelengths or below produces a separation of charge, resulting in a hole in the valence band and a free electron in the conduction band, due to the electron movement from the valence to conduction bands. These hole–electron pairs generate ROS when they interact with H₂O or O₂ [43,44]. It was described that they can cause an increase in ROS levels after exposure to UV-visible light [45]. The NBT assay in the studied samples showed that bare P25TiO₂NPs produce a large amount of ROS, which is drastically reduced by functionalization with vitamin B2 (Fig. 5). This vitamin, also known as riboflavin, was discovered in 1872 as a yellow fluorescent pigment, [46] but its function as an essential vitamin for humans was established more than sixty years later, and its antioxidant capacity was not studied until the end of the XX century [47,48]. This antioxidant role in cells is partially explained because the glutathione reductase enzyme (GR) requires it for good functionality. This enzyme is the one in charge of the conversion of oxidized glutathione to its reduced form which acts as a powerful inner antioxidant and can quench the ROS [49,50]. The cost of this action is that the glutathione is converted to the oxidized form and needs to be recovered by the GR. Consequently, the cells need more vitamin B2. Another glutathione action is the protection against hydroperoxide. This activity is also mediated by riboflavin. Therefore, local delivery of this vitamin seems to significantly help the cells in their fight to keep the oxidative balance, once they are exposed to high levels of ROS.
