Description
Brand - NADELLA
Item Number - LFE 27 NADELLA
Category - Adjusting Nut (LFE Series)
Principal Dimensions & Load Ratings (Metric):
Thread (A) - 100 x 2
Dimension (D) Ø - 125 mm
Dimension (B) Ø - 117 mm
Dimension (C) - 20 mm
Dimension (b x h) - 10 x 4
Dimension (F) Ø - 114 mm
Dimension (d) Ø - 5.2 mm
Grub Screw (Hc) - 4 x M6
Unlocking Torque - 650 Nm
Maximum Axial Load - 408100 N
Weight - 0.65 kg
Other salient points to be noted:
• LFE nuts are ideal for applications where radial clamping isn’t feasible, particularly for securing components within housings or deep cavities, and for installing bearings in such locations
• Equipped with two clamping springs placed opposite each other at 180°, they offer two main benefits over LF nuts: Improved balance for higher-speed rotation, Double the locking force in the same nut size
• When the two Hc grub screws are tightened, axial force is transmitted through 90° wedges to the threaded spring
• This action produces radial force, delivering strong clamping pressure along the thread for secure fixation
• A perpendicular contact surface to the threaded side allows precise alignment and secure clamping of bearings and other components requiring tight tolerances
• Along with notches, front-facing holes make it easy to position the nut using a spanner wrench
• Material: High elastic limit steel
• Peripheral notches: 4 x 90°
• 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
• Other versions are also available upon request: Fine-ground threads, Left-hand thread, Other sizes, Other materials
