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 63-67 HRC | |||
Fine surface finish | Ball screws | |||||
Through-hardness and high loacapacity | Automotive (transmission, steering, anti-lock brakes) | 3.175mm-30mm 62-67 HRC | ||||
Used in demanding industrial applications | Valves Couplings Locks Slides Conveyers | 30.1625mm-104.775mm 61-67 HRC |
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 Inspection | 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. |
