11.906mm(0.46874"), G10, G16, G20, High Quality Chrome Steel Ball for bearing, GCr15
Introduction
Application Fields
Gcr15 bearing steel balls are widely used in high-speed and low-noise bearings, bicycles, motorcycles, automobiles, slide rails, universal balls, luggage, electronic industries, and can also be used to grind other media.
Characteristic
Magnetic, ferritic steel, oil packaging, hardness can reach HRC60-66, the material has good wear resistance, the precision can reach 1/10th of a millimeter after cold processing into steel balls, and the surface is mirror-like. The color is chrome, but it cannot be welded. Extra strong corrosion resistance, not easy to slip, high hardness, strong wear resistance, low roughness, and will not wear the ball seat.
Good overall performance, high and uniform hardness after quenching and tempering, high wear resistance and contact fatigue strength, good hot workability, contains more alloying elements, and the price is relatively cheap.

Little knowledge of bearing steel ball
Bearing balls, as an important part of the bearing, play a very critical role. Therefore, the use effect and service life of the bearing are closely related to the accuracy and hardness of the bearing steel ball. The hardness is related to the crushing load value of the steel ball.
Crushing load is an important performance index of bearing steel balls. Semi-finished steel balls and finished steel balls in the quenched and tempered state need to be tested for crushing load. If the standard is not met, the entire batch of products may be scrapped.
Today, let’s analyze the factors that affect the insufficient crushing load of bearing steel balls:
1. Quenching overheating; 2. Quenching cracks; 3. Material cracks; 4. Shrinkage holes; 5. Slag inclusion; 6. Microscopic pores; 7. Insufficient tempering; 8. Excessive stress.
If the bearing quality is avoided in the above several items Can be greatly improved.
