CLAMPING SYSTEM APPLICATIONS

CLAMPING SYSTEM APPLICATIONS SPRING NUTS The new generation of spring nuts consists of six different models, each of which uses the same clamping technology with a spring. MOUNTING THE NUTS AND RINGS • The mounting occurs by driving the spring nuts and rings clockwise with standard spanner wrench (Din 1810) adapting onto the peripheral notches (b x h) of the nuts. • The mounting can also easily be achieved thanks to the pin-key holes on the front-side of the nuts with the adequate key. • Once in the correct position on the shaft/spindle the blocking can be simply secured by turning the Hc...

The threaded spring nuts and rings are used whenever precision mechanisms require a precision clamping as well as a powerful and safe locking: APPLICATIONS DETAILS • Power transmission and motion technology • Textile machinery • Adjusting and clamping all types of bearings • Printing industry • Mount/release of ball bearings • Elimination of back lash • Special machinery • Securing mechanical safety devices • Automotive industry • Templating spring-mounted measuring systems • Engine/turbine manufacturing • Safety nuts for use in high-temperature applications • Onshore and offshore industry...

• LR nuts are used wherever a strong radial clamping is required. SPECIFICATIONS • Material: High elastic limit steel 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...

• LRE nuts are used wherever a strong radial clamping is required. Radial clamping 2 springs Unlocking Torque • 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 threaded side allows the adjusting and securing of all types of bearings as well as other mechanical...

• LF nuts are used wherever a strong radial clamping is not possible. • The contact surface perpendicular to the threaded side allows the adjusting and securing of all types of bearings as well as other mechanical elements requiring very precise tolerances. Type 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 set-screw with cone tip 14.9 • Standard manufacturing: - 4H class precision...

CHARACTERISTICS • LFE nuts are used wherever radial clamping is not possible. They are therefore highly recommended for securing parts inside housings or deep chambers as well as for mounting bearings inside such places. Axial clamping 2 Springs • Featuring 2 symetrically opposed clamping springs at 180°, these nuts have two advantages when compared to LF nuts: - Increased balance allowing higher rotation speeds - Twice as much locking power for the same size • The axial strength activated by turning the 2 Hc grub screws is exercised onto the threaded spring through 90° wedges. • The...
