Description
Brand - NADELLA
Item Number - LF 6 NADELLA
Category - Adjusting Nut (LF Series)
Principal Dimensions & Load Ratings (Metric):
Thread (A) - 20 x 1
Dimension (D) Ø - 37 mm
Dimension (B) Ø - 32 mm
Dimension (C) - 15 mm
Dimension (b x h) - 4 x 2
Dimension (F) Ø - 29 mm
Dimension (d) Ø - 3.2 mm
Grub Screw (Hc) - 2 x M4
Unlocking Torque - 10 Nm
Maximum Axial Load - 61800 N
Weight - 0.08 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 4 screw - clamping torque: 2.5 Nm
