AI Technical Summary
Existing sealing structures rely solely on lip contact for sealing, which is insufficient to withstand harsh environments and results in poor dust protection.
It adopts a double-layer sealing structure, including a main sealing ring and a secondary sealing ring, combined with a dustproof frame and quick-release components. The main sealing ring blocks small particles, the secondary sealing ring blocks large particles, and the quick-release components enable quick installation and disassembly.
It effectively prevents dust and lubricating grease leakage in harsh environments, improves sealing performance, is suitable for various environments, and is easy to disassemble and clean quickly.
