Industrial jewels

Manufactured from the synthetic sapphire, ruby or natural agate or ceramics.

 

Cover stone polished on both sides

In assembly with a bored jewel it serves for pin seating of the gears in order to absorb axial pressures.

 

Cone bearing

In the bearing a steel shaft is turning ended with a radius smaller than the radius of the bearing cone apex. It is used in measuring instruments with a deflecting pointer (e. g. Voltmeter, ammeter).

 

Jewel with cylindrical hole

In the bearing the cylindrical steel axis of the instrument is turning. The bearing absorbs both radial and axial pressures. The bearing is also used in combination with the cover (support) jewel. In the bearing assembly the jewel provides for constant axial distance necessary for gearing engagement, e. g. in aircraft board instruments, etc.

 

Jewel with cylindrical hole without cups

In the bearing the cylindrical steel axis of the instruments is turning. The bearing absorbs both radial and axial pressures. The bearing is also used in combination with the cover (support) jewel. In the bearing assembly the jewel provides for constant axial distance necessary for gearing engagement, e. g. in aircraft board instruments, etc.

 

Jewel with olivated hole

In the bearing the cylindrical steel axis of the instrument is turning. The bearing absorbs both radial and axial pressures. The bearing is also used in combination with the cover (support) jewel. In the bearing assembly the jewel provides for constant axial distance necessary for gearing engagement, e. g. in aircraft board instruments, etc.

 

Jewel with double-sided olivated hole

In the bearing the cylindrical steel axis of the instrument is turning. The bearing absorbs both radial and axial pressures. The bearing is also used in combination with the cover (support) jewel. In the bearing assembly the jewel provides for constant axial distance necessary for gearing engagement, e. g. in aircraft board instruments, etc.

Cover stone

In assembly with a bored jewel it serves for pin seating of the gears in order to absorb axial pressures.

 

Cup bearing, polished

Between the two bearings the instrument axis is freely - turning. It is ended with a radius (steel ball) smaller than the radius of the spherical recess. It absorbs especially axial pressures.

 

Cup bearing, medium polished

Between the two bearings the instrument axis is freely - turning. It is ended with a radius (steel ball) smaller than the radius of the spherical recess. It absorbs especially axial pressures.

 

Cup bearing, finely polished (wood polished)

Between the two bearings the instrument axis is freely - turning. It is ended with a radius (steel ball) smaller than the radius of the spherical recess. It absorbs especially axial pressures. It is used as a footstep bearing of the electricity meters of all kinds.
