Product Description

1/8" Inch 3.175MM SUS420 Stainless Steel Bearing Balls G25 For Surgical

 

High precision grade G25


Finest quality AISI 420 stainless steel


Manufactured in China

 

Product description

 

The finest quality 420 Stainless steel produced in accordance with the highest industry standards.

 

These high precision G25 ball bearings are hot forged from bar stock.

 

Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating

 

to assure uniform hardness and proper microstructure for each Stainless steel ball.

 

Throughout the manufacturing process, statistical process control assures tolerance accuracy,

 

fine surface finish and consistent high quality.

 

Stainless steel balls afford the advantage of maximum hardness combined with corrosion-resisting properties.

 

This hardness, together with precise geometry and fine surface finish, makes them especially useful for bearing

 

and Valve applications where severe environmental conditions may occur.
