Description
Brand - NADELLA
Item Number - LF 19 NADELLA
Category - Adjusting Nut (LF Series)
Principal Dimensions & Load Ratings (Metric):
Thread (A) - 60 x 2
Dimension (D) Ø - 80 mm
Dimension (B) Ø - 73 mm
Dimension (C) - 20 mm
Dimension (b x h) - 7 x 3
Dimension (F) Ø - 72 mm
Dimension (d) Ø - 4.2 mm
Grub Screw (Hc) - 2 x M5
Unlocking Torque - 130 Nm
Maximum Axial Load - 263800 N
Weight - 0.33 kg
Other salient points to be noted:
• LF nuts are designed for situations where direct radial clamping is not feasible
• By tightening the front-facing Hc grub screw, axial force is transmitted through 90° wedges to the threaded clamping spring
• This action generates radial force on the spring, producing strong clamping pressure on the thread for secure locking
• The flat surface perpendicular to the threaded end supports accurate alignment and firm locking of bearings and other precision mechanical components
• In addition to notches, front-side holes enable easy installation 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
• Values obtained with Hc grub screws: M 5 screw - clamping torque: 5 Nm
