Conclusion

The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.

Hydraulic cylinders operate on the principle of Pascal's Law, which states that pressure applied to a confined fluid is transmitted undiminished throughout the liquid. Engine hoists typically use these cylinders to lift engines and other heavy components by converting hydraulic pressure into linear motion. However, constant use can lead to issues such as leaks, reduced lifting power, and eventually, cylinder failure.

Turmeric has been used by humans for nearly four thousand years. For thousands of years, it has been used as a dye, as a cooking spice, and as a material used in medicine. Sanskrit texts of its use as a spice date back to ancient Indian times. The name Turmeric comes from the Latin Terra merita because its roots, when ground, are golden. The spice is made from the turmeric (Curcuma longa) plant in the ginger family. Turmeric is grown for its stems. The stem is dried and ground into a yellow powder with the bitter sweet taste we know and love.
