What is tolerance ring?

A tolerance ring is a type of mechanical component used to create a friction fit between two parts, often in assemblies where precise alignment and secure connection are required. It typically consists of a circular metal ring with a series of radially-oriented projections or lobes that deform when pressed into a counterpart, allowing for a snug fit while accommodating slight variations in dimensions. Tolerance rings are commonly used in applications such as automotive, electronics, and machinery, providing benefits like vibration damping and ease of assembly.
