The adapter ring allows you to mount the saw blade to your miter saw. Standard twelve-inch saw blades have one-inch arbor holes in them. Most miter saw arbors are 5/8 of an inch, so the blade's arbor hole is too large to fit firmly onto the arbor shaft. The adapter ring fits into the blade hole and onto the arbor shaft, allowing you to use standard twelve-inch blades. The adapter blade can wear, causing the blade to wobble or vibrate.
