Product Description

1/4" =6.35mm Silicon Nitride Ceramic Ball for Bearing Si3N4 Grade G5 1. Product: Diameter Size : 1/4" = 6.35 mm ceramic ball Material: Silicon Nitride Ceramic Ball Si3N4 Grade:G5 (1). Chemical Characteristics Density: 3.23 g/cm3 Poisson’s Ratio: 0.26 Hardness(Hv): 1500 MPa Flexural Strength(@ R.T.): 720 MPa Flexural Strength (700ºC):450MPa Compressive Strength (@ R.T.):2300MPa Fracture Toughness, K Ic : 6.2 MPa•m 1/2 Thermal Conductivity (@ R.T.):25 W/m•k Electrical Resistivity (@ R.T.) :>1013Ω•mm2/m Max.Use temperature: 1050 °C (2). Advantage: Compared with steel ball, ceramic ball has following advantages: a. 59% lighter than steel ball, which means less centrifugal force and less wear on the groove during high speed and acceleration. b. 44% larger elastic modulus, which means less deformation under load c. Harder with Rockwellhardness as 78 d. Smaller friction coefficient e. Only 1/4 coefficient of thermal expansion of steel, can endure sharp fluctuation of temperature f. Superior s6urface finish can be achieved, Ra could be 4~6 nm g. Can endure high temperature with high hardness and strength up to 1050°C h. Never rust, and can roll without lubrication. i. More corrosion resistant than steel. j. Free of metal contamination. k. Non-magnetic l. Electric isolation m. No adhesive-wear with metal (3)Application: Si3N4 ball can be used in all bearings with special requirement: high speed bearing, high precision bearing; vacuum bearing; high/low temperature bearing, non-magnetic bearing, high precision ball screw; Si3N4 ball can also be used as valve ball and metering ball in chemical pump, high-temperature pump, metering pump. Si3N4 ball can also be used in linear slider for high temperature and corrosion resistance. 2.
