TECNICHAL JEWELS...

 (industrial jewels , jewelled bearings , watch jewels , bearings, orifices)

 

Products made in  synthetic sapphire, synthetic ruby, natural agate, ceramic  witch have remarkable characteristics :

extreme hardness, wear resistance, corrosion resistance, high temperature suitability, thermal stability, electrical insulation,

high surface smoothness.

The high degree of finishing and precision are too much important to guarantee the best mechanical and wear performances.                                                                                                                                                                                                                                                                      Fields of application:
Gauges, measuring instruments, water meters, watches, mechanical, machines,
electronic, electro technical, texile,medical applications .  

 

        CUP  JEWEL  

This bearings is suitable to absorb axial pressures. the spherical recess has a constant radius and a high surface  smoothness. In the spherical recess the shaft of the instrument turning and it is freely. The bearing radius is bigger than the shaft radius. The cup jewel is generally used with a semi spherical pivot and for vertical shaft applications. .                                                    

        CUP JEWEL DOUBLE

The characteristics of this jewel are the same of the cup jewel. The double cup recess allows to assemble  with automatic system, without need to orient the jewel.

                                          

        CUP JEWEL WITH HOLE

This jewel is suitable to absorb radial pressures. The shaft of the instrument turning in the bearing.

        FLAT JEWEL

 

This jewel is suitable to absorb axial pressures.  

Generally it is used as thrust bearing in combination with a cup jewel with hole (ring jewel). The flat or both flats are highly polished.

        DOUBLE CUP JEWEL

   It is used in special applications.

  

        VEE  JEWEL

In the conical recess the shaft of the instrument turning and it is freely. Vee jewel (as cup bearing) work best with minimum contact between the pivot (shaft end) and the jewel. In the vertical applications the optimum radius of a V-bearing is about three times the pivot radius. The Vee jewel can be used horizontally too.

        VEE JEWEL WITH HOLE

(orifice jewels or nozzles) It is used in several applications :
 High pressure
Water-jet ,Flow meters, ink jet printing ,  control unit (gas, liquid), nozzles for abrasive solutions.
