  • Product Details

Generic off-the-shelf seals often degrade quickly under hydraulic pressure and shaft friction, triggering fluid leakage and rising routine service expenses. This 572-0340 oil seal adopts asymmetrical lip structure and optimized anti-extrusion design. It isolates internal hydraulic fluid from external dust and grit, supports flexible bulk stocking for suppliers, and maintains long-term tight sealing reliability for construction machinery drive systems.
