功能

• The oil seal prevents water, chemicals, and gas, including lubricating oil, from leaking into the machine, while preventing dust and soil from entering the machine.
• The application depends on the sealing material.
• Synthetic rubber, which constitutes a seal lip, is baked and bonded to the metal ring, and the shaft is held appropriately by the "spring" incorporated to enable sealing of the moving part.
• Oil seal when the object to be sealed is on one side and there is minor dust on the other side.
