Our Precision Bearings are
used for precision devices such as HDD (Hard Disk Drives)
and Indicators for Analog Measuring Instruments in which long-term
reliability is needed.
The materials used are Hard Alloy, Ruby, Sapphire, Zirconia
and other ceramics. Ceramic Bearings are especially required
for Corrosion-Resistance, Pressure Tightness, Heat-Resistance
and Insulation Performance applied for Precision Electronic
Devices. The dimensions and tolerances of the Ceramic Bearings
have accuracy at submicron leve
