Locking nut LR series

steelthreadedmechanical clamping

• LR nuts are used wherever a strong radial clamping is required. • The radial strength activated by turning the Hc grub screw is applied onto the threaded spring. • The contact surface perpendicular to the threaded side allows the adjusting and locking 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 precison 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 locking torque - Other sizes - Other materials *Values obtained with Hc grub screws: M 6 screw - clamping torque 8 Nm M 8 screw - clamping torque 18 Nm M 10 screw - clamping torque 36 Nm
