a Dual-Material Collaborative Design for This Specialty Seal Ring

Product Description

What is a sealing ring?

The sealing ring is wrapped around the edge of the protective lens and is located between the lens and the lens holder.

It prevents dust and slag generated by cutting from invading the lens surface, protects the inside of the lens holder and isolates external moisture and oil.

Dust and pollution prevention

Protects precision optical systems

 Shock absorption and buffering

It blocks metal dust, smoke and debris generated during the cutting process, avoids contamination of lenses and optical components, and significantly extends the life of the equipment.

Isolates corrosive media such as water vapor and oil, avoids damage to lens coating or optical path deviation, and maintains laser focusing accuracy

Some spring energy storage sealing rings (such as PTFE+stainless steel spring structure) can absorb equipment vibration and reduce the risk of optical component deviation caused by vibration
