Moreover, specific demographics, such as athletes and older adults, often have unique nutritional requirements. Athletes may seek protein powders or amino acids to support muscle recovery and enhance performance, while older adults might turn to calcium and vitamin D supplements to promote bone health. The tailored nature of supplements makes them an appealing option for these groups, as they can directly address individual health needs.

One of the primary applications of chemical treatment systems is in wastewater treatment. Industrial facilities often generate wastewater laden with contaminants, including heavy metals, organic compounds, and pathogens. Chemical treatment can involve several processes, such as coagulation, flocculation, sedimentation, and disinfection. Coagulation is the process in which chemicals, like alum, are added to the wastewater to help particles clump together into larger aggregates, known as flocs. Once these flocs are formed, they can be removed from the water through sedimentation, where they settle to the bottom of a tank. This step is crucial for reducing suspended solids and turbidity in the water.

- Rotary shaft oil seals are typically installed on rotating shafts to provide a barrier against oil, grease, water, and other liquids. They are designed to withstand high pressures, temperatures, and speeds, making them suitable for a wide range of applications, including automotive, aerospace, marine, and manufacturing.
Runouts need to be minimized. The most common causes of the center of rotation movement are shaft whip and bearing wobble. The issue is even worse when there’s misalignment. Contrary to widespread assumption and practice, misalignment cannot be corrected or made up for by using flexible couplings.

ERIKS
ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
CS
An oil seal, also known as crankshaft retainer, is a small device, but essential to ensure the proper engine operation. It plays a key role in all moving parts of an engine, acting as a physical barrier. This mechanical seal fulfils the dual purpose of sealing a rotary shaft to maintain the necessary lubrication (avoiding leaks) and preventing other foreign matter from contaminating shafts and bearings in the rotary shaft equipment.
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.
