3. 1. What is the Sleeve bearing?
Sleeve bearing is used to rotating shaft to rotate accurately and smoothly.
Reduce energy loss and heat caused friction.
So prevent damage to componets.

4. 2. Material ◎ Iron Easy to obtain. Price is cheap and easy to molding.
->Pure iron’s hardness is low.

5. 4. Casting When machine rotating, pour molten steel.
◎ Centrifugal casting
When machine rotating, pour molten steel.
Produce sleeve bearing and shaft.
◎ Gravity casting
Pour molten steel to mold.
Only use gravity.
Produce any kind of shape.

6. 3. Heat treatment ◎ Normalizing Increase hardness and toughness.
Remove remaining stress.

7. 5. Shot blast ◎ Shot blast Remove rust used to compressed air or
strong shock.

8. 6. Ultrasonic test By using ultrasonic, test the internal flaw.

9. 7. Deburring Using the high pressure water remove the chip,
fingerprint and impurities.

10. 7. Inspection
Dimension check.

11. 8. Packing/Delivery
