Rotary seals are designed for applications involving shaft rotation, such as hydraulic motors. They prevent leakage while allowing high-speed rotation. Materials like PTFE or filled compounds resist wear and heat. Lip-type rotary seals are common, balancing sealing and friction. High-pressure rotary seals use energizers for better performance. Proper installation prevents twisting, en... https://globalsealstech.com/hydraulic-seals/
