JFK Locking rings

Precision axial locking and positioning

Compensation rings and Seeger retaining rings for all axial fastening requirements.

JFK rings are precision mechanical components for axial locking and positioning of bearings and other components on shafts and inside bores. The range is divided into two main families: compensation rings for play-free mounting of ball bearings, and Seeger retaining rings, also known as snap rings or circlips, for fast and secure axial locking. Both types are made of high-performance steel and are available in a wide range of sizes.
