(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,
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,
electronic, electro technical, texile,medical applications
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.
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
DOUBLE CUP JEWEL
It is used in special
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
