Locking nut LF series

steelthreadedprecision

• LF nuts are used wherever a strong radialclamping is not possible. • The axial strength activated by turning the front Hc grub screw is applied onto the threaded clamping spring through 90° wedges. • The resulting radial strength applies onto the clamping 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 securing 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 run-out of the nuts and rings, all threading and contact face machining operations are performed in one setting. • Grub screw: Hc type set-screw with cone 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
