In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.

The concept of a swing extension spring draws parallels to the physics of springs in engineering. In a mechanical context, springs are designed to store potential energy, which is then converted into kinetic energy when released. This principle can be applied to athletic movements, where the body acts like a spring. By effectively utilizing the body's natural biomechanics, athletes can maximize their performance.
