Precision centering ring with O Ring
A Precision Centering Ring with O ring is a high-precision component used to ensure precision mechanical assembly and sealing. It is commonly used in optical equipment, instrumentation, vacuum systems, and other applications that require highly accurate alignment and sealing performance.
Structure and Working Principle
Precision center rings are usually made of metallic materials, such as stainless steel or aluminum alloy. It features precise size and shape control to ensure highly accurate alignment and centering capabilities. The surface of the center ring is precision machined and treated to provide a flatness and finish.
O-rings are usually made of an elastic material (such as rubber or silicone) and have a donut-shaped cross-section. It is installed into specific notches or grooves in the precision center ring.
