Shaft seals serve as barriers between rotating shafts and stationary components. They are integral in containing lubricants and preventing external contaminants from entering the machinery. In high-temperature environments, the challenges are amplified. High temperature shaft seals must resist thermal degradation, maintain their sealing properties, and endure the harsh conditions often present in such settings.

Applications of Hydraulic Shaft Seals

Dust proof seals come in various forms, tailored to meet specific requirements across different applications

Regular maintenance and inspection of oil seals are essential to prolonging their lifespan and preventing unexpected failures. Signs of a failing oil seal include leaks, increased friction, and unusual noises coming from the machinery. If any of these symptoms are present, it is important to replace the seal promptly to avoid damage to the equipment.

Both P25TiO₂NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.
