  NUTU-NUT
CONSTRUCTION AND FUNCTION
 
Figure1

The FUJILOK U-NUT is
comprises of a nut and stainless steel function ring spring.
The friction ring is attached to
the top face of the nut
by crimping.
 
Figure2

A stress P is produced by the spring effect of the stainless steel friction ring coming into contact with the screw thread as shown in the illustration. The P and its reaction force P' press strongly against the screw threads to produce a frictional torque(prevailing torque)above The prevailing prevents the turning of the screw,generation an excellent locking effect.

  FINE U-NUTFINE U-NUT
CONSTRUCTION AND FUNCTION
 
Figure The FINE U-NUT is a one piece item where the locking function is performed by a spring peened into the top of the nut. In use the spring bears on the flank of the shaft thread with force .P generating reaction force P'in the screw threads with a resulting high friction torque (prevailing torque). The nut therefore remains locked in position.
   
FEATURE
LABOUR SAVING
MACHINING OF A SHAFT KEYWAY IS ELIMINATED.		 SHAFT BALANCING
LACK OF KEYWAY AND DESIGN OF NUT ENSURES SHAFT IS PERFECTLY BALANCED.
SIMPLIFIES ASSEMBLY
NO TAB WASHER IS REQUIRED REDUCING COSTS AND REMOVING POSSIBILITY OF THE TAB WASHER BEING INCORRECTLY INSTALLED.		 WEIGHT SAVING
THINNER WALL HOLLOW SHAFT CAN BE USED COMPARED TO THOSE WHERE A KEYWAY IS REQUIRED THEREBY SAVING WEIGHT.
WORKABILITY
NO SKILL OR TECHNIQUE IS REQUIRED FOR ASSEMBLY.		 REUSABLE
THE FINE U-NUT CAN BE RE-USEABLE.
FUNCTIONALITY
FINE ADJUSTMENTS ARE EASILY ACHIEVED TO OBTAIN OPTIMUM BEARING ASSEMBLY. 		ECONOMICAL EFFICIENCY
INVISIBLE COSTS ARE REDUCED AND TOTAL COST REDUCTION IS ACHIEVED.

  NUTTWIN FU-NUT
CONSTRUCTION AND FUNCTION  

Figure
 

The TWIN FU-NUT has two friction rings and a spacer which are secured to the upper surface of the nut, as shown above.
The two friction rings are arranged so that stress P generated by the spring action and the reaction P' act symmetrically about the shaft centre. This arrangement ensures an even contact force F around the contact face.
