1/8 inch 52100 high grinding chrome steel ball bearing steel balls

In Ball Bearings
 Grade 20, hardened chrome steel balls are applicable.
 Manufactured in high carbon high chrome steel, also called bearing steel (AISI-52100 / EN-31)
 Ball Diameter Tolerance: 0.000020 inch or 0.0005 mm or 0.50 microns.
 Basic Diameter Tolerance: ± 0.0001" or ± 0.0025 mm or ± 2.50 microns

In Bicycles

 Grade 200 or 500 are suitable.
 Manufactured in hardened high carbon high chrome steel (AISI-52100 / EN-31 / EN-9 / M.S.)
 Generally used diameter (in inches) are 1/8", 1/4", 3/16", 5/32"

As Agitators
In the plating bath for plating zinc and lead
In the plating baths, chrome steel balls of 1, 1.5 and 2 mm diameters are used. High tolerance is not required and hence, grade 1000 polished ball is generally suitable. At times, stainless balls of 304 steel are also used. 

In paint spray cans
Here balls of 3/8" or 10 mm diameters, G-1000 are used. The steel balls stir up the paint and mix it thoroughly.

 In personal care products like nail polish
Because of non-usage, the fluid coagulates and the bottle is shaken to homogenize the fluid and make it free flowing. The bottle contains a steel ball which is used as an agitator ball to help in achieving the above when the bottle is shaken. Because of the fluid, the steel balls can be prone to corrosion, hence AISI 316 stainless balls are preferred. 3 and 5 mm sizes (1/8" and 3/16" diameters) are generally used. Grade   -1000 is suitable for this application.

1.Raw Material

Each batch of raw material steel is inspected and classified according to different material (carbon, stainless, chrome), size and quantity, which marked with the Material Cert. The qualified steel comes to the quarantine area; the unqualified will be rejected with a record.

2. Wire Drawing

The steel is made into different sizes according to the needed requirements.

3. Heading

The raw material certified is worked on high-speed casting machines to cast into different size pieces.

4.Flashing

This step of the production process involves rolling the pieces between discs with concentric grooves to eliminate signs of casting and to increase the precision of the ball.

5. Heat Treatment

Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be achieved with the materials used.

6.Lapping  i (Grinding)

Successively several careful grinding processes using ceramic grinding wheels give greater dimensional precision and prepare the balls the next, final lapping process. 

7. lapping ii

 This procedure gives the ball a perfectly shiny, compact and defect-free surface, with very low surface roughness, much lower than that required under GB/308-2002

8. Selecting and Final Inspection

The sorting machines together with the manual

 detecting  and  modern testing processes, largely ensures the high quality of our products.
