674-1H Rotary Oil Seal for Fan Drive Shaft

Description of  674-1H Rotary Oil Seal  for Fan Drive Shaft

The 674-1H rotary oil seal is a key sealing component specifically designed for the drive shaft of fans. Its main function is to effectively isolate lubricating oil from the external environment under high-speed rotation, preventing oil leakage and impurity ingress, thereby ensuring stable fan operation and extending service life. This oil seal is widely used in industrial ventilation systems, ventilation equipment, and related power transmission devices, especially in high-speed, high-temperature, and complex media environments, where it demonstrates excellent sealing performance and reliability.

The 674-1H rotary oil seal is typically made of materials with excellent mechanical strength, aging resistance, and a wide temperature adaptation range, maintaining stable physical properties in high-temperature oil or dry friction conditions. Some special models also use polytetrafluoroethylene (PTFE) composite materials, further enhancing wear and chemical resistance, making them suitable for working environments with corrosive media or extreme temperatures.
