YDTech™ supplier of ceramics Si3N4 needle and cylindrical rollers! OEM of silicon nitride rollers, balls, bearings, rings, tube, blocks, shafts in china.
silicon nitride, mainly consisting of si3n4, has excellent thermal shock resistance and high-temperature strength. these properties make it ideal for use in rollers,balls,bearings, rings,tube,blocks,shafts bearings, tappet shims, buckets, high pressured pumps parts, turbocharge rotors, rocker arm tips, welding location pins, squeeze rollers for radiator tube manufacturing etc. for its superior mechanical reliability and wear resistance and corrosion resistance.
non-ferrous foundries: thermocouples sheaths, riser tubes, heater tubes, valve rods, valve seats, aluminium powder atomizer tubes, molten metal pumps parts, rotor for de-gassing shaft, launders due to high temperature capacity, excellent thermal shock, non-wetting propertiesstyluses rods.
applications of silicon nitride (si3n4) ceramics for oil and gas industries: sleeves, plungers, needles, compression rings, seals etc. are used for the harsh environment produces chemical, wear, corrosion and high temperature challenges that can be met through the use of dense silicon nitride
applications of silicon nitride (si3n4) ceramics for balls and bearings: fully dense various size balls , fully dense ceramic bearing, roller bearing, tapper roller bearings & plain bearings for 60% lighter weight, electrical- magnetic insulating, 70% higher speed, chemical resistance, high temperature etc. also hybrid bearing having ceramic balls rollers for high strength
