Locking nut LRE series

steelthreadedprecision

• LRE nuts are used wherever a strong radial clamping is required. • Featuring 2 symetrically opposed clamping springs at 180°, these nuts have two advantages when compared to the LR nuts: - Improved balance allowing higher rotation speeds - Twice as much unlocking torque for the same size. • The radial strength activated by turning the 2 Hc grub screws is exercised onto the threaded clamping spring. • The contact surface perpendicular to the threa- ded side allows the adjusting and securing of all types of bearings as well as other mechanical elements requiring very precise tolerances. 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 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 - 2 twinned screws for increased unlocking torque - Other sizes - Other materials
