Hebei Hankai hydraulic motor oil seal

The design of high-pressure rotary shaft seals typically includes a flexible sealing lip that makes contact with the rotating shaft, combined with a robust outer component that holds the seal in position. The materials used in these seals must be durable and resistant to wear, heat, and chemicals. Common materials include elastomers like nitrile rubber, fluorocarbon rubber, and special composites designed for high-performance situations.

Moreover, wiper seals help in the effective expulsion of any debris that might have accumulated on the rod during operation. This is particularly important in environments where dirt and pollutants are prevalent. By clearing away particles before they can enter the cylinder, wiper seals extend the overall lifespan of the hydraulic system, reducing maintenance costs and downtime.

Titanium dioxide is a naturally-occurring mineral found in the earth’s crust. Because of its white color, opaqueness, and ability to refract light, the ingredient is often used as a pigment, brightener, and opacifier, which is an ingredient that makes a formulation more opaque. Titanium dioxide is also a UV filter and so is an effective active ingredient in sunscreens. It’s often used in cosmetic loose and pressed powders, especially “mineral powder” cosmetics, in addition to other cosmetics, lotions, toothpaste, and soap.

As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.
