Stainless Steel Ball AISI440C 5.556mm G10
The Stainless Steel Ball AISI440C 5.556mm G10 bearing is a Stainless steel ball with an inner diameter of 5.556 mm , an outer diameter of 5.556 mm, a width of 5.556 mm. It typically uses G10/G25/G50/G100/G1000 grade precision tolerances and heat treatment type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Feature: Good wearing, excellent surface quality, and high hardness.
AISI 440C STAINLESS STEEL BALLS
Size: 0.5mm-50.8mm
Grade: G5 to G1000
Martensitic stainless steel balls, they are characterized by remarkable hardness, wear resistance, surface finishing, narrow dimensional tolerances. For that reason this type of steel is frequently used in precision devices. Balls are provided in the passivated state.
