Locking nut LFE series

steelthreadedprecision

• LFE nuts are used wherever radial clamping is not possible. They are therefore highly recommended for securing parts inside housings or deep chambers as well as for mounting bearings inside such places. • Featuring 2 symetrically opposed clamping springs at 180°, these nuts have two advantages when compared to LF nuts: - Increased balance allowing higher rotation speeds - Twice as much locking power for the same size • The axial strength activated by turning the 2 Hc grub screws is exercised onto the threaded spring through 90° wedges. • The resulting radial strength applies onto the threaded spring. The clamping pressure applied onto the threaded surface of the spring allows for a powerful locking. • The contact surface perpendicular to the threaded side allows the adjusting and clamping of all types of bearings as well as other mechanical elements requiring very precise tolerances. • In addition to the notches, the holes located on the front side allow an easy positioning of the nut by mean of a spanner wrench. SPECIFICATIONS • Material: High elastic limit steel • Peripheral notches: 4 x 90° • To ensure squareness and minimum runout of the nuts and rings, all threading and contact face machining operations are performed in one setting. • Grub screw: Hc type with dog-point tip 14.9 • Standard manufacturing: - 4H class precision threading - Right-hand thread - Fine-ground contact face - Marquing on the opposite side - Black oxide OPTIONS • Other versions are also available upon request: - Fine-ground threads - Left-hand thread - Other sizes - Other materials
