Class Precision Bearing Steel Ball Screw Steel Ball Ball Bearing Steel Ball 3.0mm/10 Grains-Bearing Steel Ball 3.5mm/10 Grains

Product gross weight: 1.0kgMechanical hardware: bearingsMaterial: Other①High-quality raw material road bearing steel, the main steel grade is Gcr15; high-carbon Ming bearing steel Gcr15 is the world's largest production of car-supporting steel, with a carbon content of about 1% Wc and a chromium content of about 1.5%, accounting for the world's bearings More than 80% of the total steel production.②High-precision rolling bearing steel balls require high dimensional accuracy of steel. This is because most of the bearing parts have to be pressure-formed to accurately meet the requirements of G5-G40 (the smaller the number, the higher the accuracy).③Long service life For bearing steel, surface defects include cracks, slag inclusions, burrs, oxide scales, etc., and internal defects include shrinkage holes, bubbles, white spots, severe porosity and segregation. These defects have a great impact on the processing, performance and life of the bearing. It is clearly stipulated in the bearing material standard that these defects are not allowed
