FAQ

A spiral retaining ring like the SP 130 is coiled from flat wire and has no protruding lugs or ears. This provides 360-degree contact with the groove, a more uniform load distribution, and often allows for a more compact and aesthetically pleasing design compared to traditional snap rings which have lugs for installation pliers.

The Seeger SP 130 is typically manufactured from high-quality carbon spring steel (such as SAE 1060-1090). This material is chosen for its excellent spring properties, allowing the ring to be compressed for installation and then expand back to its original shape to seat securely in the groove, providing high thrust load capacity.

While it's possible to install spiral rings by hand by winding them into the groove, it is not recommended, especially for larger sizes like 130mm. Specialized installation tools are available that compress the ring and guide it into the housing groove safely and without causing damage or overstressing the ring. For removal, the ring can be unwound from the groove using a small flat-bladed tool at the removal notch.
