High-precision bearing - Import export

Silicon Nitride Ceramic Balls are widely used on bearings with extreme performance requirements, such as: High-speed bearings, high precision bearings, vacuum bearing, high / low-temperature bearing, non-magnetic bearing, high precision ball screw; it is also used as valve ball, measuring ball for the chemical pump, heat pumps, metering pumps. Its excellent properties including: Good corrosion resistance withstands attacks from harsh chemicals and environments. High-Temperature Hardness is twice that of steel, Silicon nitride ceramic balls retain their strength and hardness up to 1800 degrees F.Lightweight, silicon nitride ceramic balls’ density is 3.20g/cm3 and weighs 45% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration, so greatly extending the service life. Superior Surface Finish is conducive to improving working speed and reach higher accuracy.

We offer planetary gearboxes with varied backlash degrees such as normal (only needs torque output), precision (max backlash 13 or 15 arcmins), high precision (max backlash 8 or 9 arcmins), and super-high precision (max backlash 4 or 5 arcmins).
