Pure PTFE spiral elastic back up ring

Spiral back up ring, also known as spiral elastic back up ring, is made by rolling flat metal wire, 

after heat treatment and surface treatment, it has good elasticity and toughness.

Spiral back up ring has the following characteristics:

No gaps-the shape is a continuous circle, fully contacting the assembly

The inner circle is smooth and complete, and does not interfere with the mating parts

No burrs on the inner and outer diameters, easy to disassemble

No corner waste is generated during the production process, saving materials

There is no need for molds, and the production cycle is short. By changing the thickness 

of the material and the number of turns, it can be easily made into light load, medium load and heavy 

load.
