Lispring 2-turn external spiral retaining rings are designed for shaft applications requiring reliable axial retention. Formed by coiling flat wire, the ring provides a 360° retaining surface without protruding ears, helping avoid interference with mating components. The coiling process produces no stamping scrap, while the design allows easy installation and removal.

Standard sizes are available from 6 mm to 400 mm, with custom sizes from 2 mm to 3000 mm. Available series include carbon steel and 304 stainless steel, with medium-duty and heavy-duty configurations to meet different application requirements.

These retaining rings are suitable for a wide range of applications, including automotive and new energy vehicles, aerospace, medical equipment, robotics, construction machinery, and other industrial assemblies requiring secure shaft retention.
