One of the key challenges in high-speed rotary shaft seals is managing heat generation. The friction caused by the seal's contact with the shaft can lead to significant heat build-up, potentially affecting the seal's integrity and lifespan. To combat this, advanced materials and designs, such as thermally conductive fillers, are employed to dissipate heat efficiently To combat this, advanced materials and designs, such as thermally conductive fillers, are employed to dissipate heat efficiently
