Learn how to manually install a Lispring external spiral retaining ring onto a shaft groove with ease.
Installation Steps:
• Positioning: Align the leading end of the spiral retaining ring over the top edge of the shaft.
• Spiral Installation: Gradually wind and press the ring downward around the shaft diameter until it guides smoothly into the mounting groove.
• Groove Engagement: Make sure the entire retaining ring is fully seated in the groove, providing a secure 360-degree fit around the shaft.
Designed for smooth manual assembly, Lispring external spiral retaining rings offer quick installation and reliable axial retention for shaft applications.
This installation method is suitable for a wide range of mechanical assemblies where secure positioning and convenient installation are required.

This 3D animation demonstrates the tool-assisted installation of a Lispring external spiral retaining ring on a shaft.

A guide tool is positioned at the shaft end, and the ring is placed over the guide. A pusher sleeve then moves axially to push the ring into the shaft groove. Cutaway views illustrate the tool arrangement and show how the ring seats in the groove.

The demonstration provides a visual reference for engineers and assembly teams evaluating shaft assembly methods and installation tooling. Tooling dimensions should match the selected retaining ring, shaft and groove specifications.

This video shows the proper method for measuring the outside diameter of a single turn wave spring. A caliper is used to find the largest diameter point and obtain an accurate measurement. This method applies to both gap type and overlap type wave springs designed for clearance fit applications.

Wave Spring Features: Premium Materials: Crafted from stainless steel, carbon steel, or exotic alloys like Inconel, tailored for temperature resistance, corrosion resistance, and load demands. Precision Forming: CNC machines shape flat wires into accurate wave patterns, ensuring tight tolerances and consistency. Enhanced Properties: Heat-treated for strength, elasticity, and fatigue resistance, with surface finishes like passivation or black oxide for durability. Retaining Ring Features: Robust Construction: Made from carbon steel, stainless steel, or specialized alloys to withstand heavy axial loads and harsh environments. Advanced Processes: Laser cutting or stamping ensures precise shapes, while edge treatments guarantee smooth surfaces for component safety. Enhanced Durability: Heat-treated for optimal strength and flexibility, with corrosion-resistant coatings like zinc plating or passivation.

This video demonstrates how to determine the free height of a multi-turn wave spring. Begin by lowering a flat measuring surface onto the spring and continue until the surface is in contact with all of the upper waves. At this point, the spring is at its free height.

The video also shows how further compression brings the wave spring to its specified work height, where it generates the required axial load. Understanding free height and work height is important for proper spring selection, assembly, and performance verification.
