Garter Springs

Garter springs are coiled steel springs that are connected at each end to create a circular shape — basically an extension spring with the ends connected to form a circle. 

产品特性
They are a type of extension spring with ends connected to make a garter belt that will exert force from its inner diameter.  A compression garter spring exerts outward radial forces, while extension garter springs exert inward radial forces.  These springs are supplied and assembled with the ends already interlocked.
应用
The primary application is to maintain lip seal pressure on a shaft and include:
• Oil seals
• Shaft seals
• Small drive belts
• Belt-driven motors
• Electrical connectors
