Products Description
TTO rotating V-shaped sealing rings are double-acting rotary seals, usually made of elastomeric materials such as PTFE or NBR, with a unique V-shaped cross-section. This design enables it to effectively prevent liquids, dust, and other contaminants from entering the space between the rotating shaft and the housing while maintaining the integrity of the lubricant.
Performance Features
High wear resistance and low friction: TTO rotating V-shaped sealing rings have excellent wear resistance and low friction characteristics, which enables them to reduce heat generation and extend seal life when operating under high speed and high-pressure conditions.
Bidirectional sealing ability: This V-shaped sealing ring can work under positive or negative pressure conditions to provide a reliable sealing effect.
Anti-pollution ability: Due to its unique design, it can effectively prevent external contaminants from entering the sealing area while preventing internal lubricant leakage.
Structure and working principle
- Structure: TTO V-rings consist of an elastic rubber(NBR,PTFE) body and a conical sealing lip, without metal or fiber reinforcement.
- Working principle: The seal is installed on the shaft through its elastic interference fit and rotates with the shaft. The conical sealing lip fits tightly with the contact surface perpendicular to the axial direction to play a sealing role.
