|What is SUJ2?||Features||Applications||Hardness|
|SUJ2 is a high-carbon chromium bearing steel in conformity with JISG4805.|
Non-metal inclusions,which have a harmful effect on the durability of steel, are minimized by the vacuum degassing method.
|High load bearing||Bearings||0.8mm-3mm|
|Fine surface finish||Ball screws|
|Through-hardness and high loacapacity||Automotive (transmission, steering, anti-lock brakes)||3.175mm-30mm|
|Used in demanding|
|Manufacture process of steel balls|
|Step 1 Heading||Balls blanks are cold headed from rolls of wire.|
|Step 2 Flashing||Rolling balls between two hard alloy plates to removes the slight band|
and small protrusions.
|Step 3 Heat treat||Heating balls to a high temperature in furnace and quenching balls in a liquid bath.|
|Step 4 Rough grind||Rolling balls between the face of a fixed iron plate and a very hard fire-grit grinding wheel. Then rolled the hardened ground balls between two cast iron plates.|
|Step 5 Cleaning||The final production operation cleans the finished balls and adds a shiny luster.|
|Step 6 Final|
|Balls are gauged, visually inspected and subjected to other quality tests to insure|
every customer's specifications are achieved.
|Step 7 Packaging||The balls are packaged in accordance with customer specifications for shipping.|
