Jeweled bearing exhibit a rare combination of
design characteristics that make them the bearing of choice over
Jeweled bearings are unparalleled in achieving
extremely low break-away friction, long life, and the ability to
withstand harsh environments.
Sapphire and Glass Vees are highly recommended
in all low torque, low load, low speed or oscillating applications.
Ring Jewels, Sapphire, End Bearings, Rollers and
Balls all fill the need for higher loads and speed. Because Sapphire
is next to diamond in hardness, wear is negligible in normal usage.
It is not unusual to find a precision Jeweled time piece from the
turn of the century still keeping perfect time.
Sapphire is unaffected by acid or alkaline environments
even at elevated temperatures. It is therefore in high demand for
applications in Petrochemical, Process Control and Medical Instrumentation.
With melting temperatures over 2,000 degrees C,
Jeweled Bearings find their way into some very hot situations. In
applications where lubrication cannot be tolerated, perhaps because
dust or debris in the instrument could cause contaminate build-up,
Jeweled Bearings are a safe alternative.
Repeatability of tolerance, high surface finishes
and close concentricity are other favorable plus points.
