34.90mm(1.374016"), Metal Bearing Steel Ball For Ball Bearing, G28
Introduction
Our company offer AISI 52100 chrome steel balls which are used in the ball and roller bearing industry and for a variety of automobile applications. These chrome steel balls have excellent surface quality. They offer superior wear resistance, high hardness and high load bearing capacity as a result of through-hardening.
1. These high precision ball bearings are hot forged from bar stock. Great for applications where there will be extreme rotation.
2. Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.
3. Ball hardness is controlled within the 60-63 HRC range as measured on parallel flat surfaces. The steel balls come lightly lubricated to keep their perfect polish.
4. Durable, compressive, wear-resistant, strong toughness, durable and longer service life.
5. Precision manufacturing, standard workshop, large-scale production, automated equipment testing to ensure quality.
6. Bearing balls are used in automotive applications, for semi-precision bearings, and in commercial applications such as casters, locks, and drawer slides.
7. Other applications for steel bearing balls include bicycles, casters, drawer slides, door locks.
Chrome steel ball knowledge
Chrome steel balls play a very critical role as an important accessory in the bearing. Therefore, the use effect of the bearing is closely related to the service life and the accuracy of the bearing steel ball. and the size of the hardness is related to the crushed load value of steel balls.
Crushed load is an important performance indicator of the bearing steel ball. Semi-finished steel balls and finished steel balls in the quenched fire treatment state need to detect crushing loads, such as do not meet the standard, and the entire batch of products may be scrapped. Today, we analyze the factors affecting the insufficient pressure of the chrome steel ball.
1. Quench overheating 2. Quenching crack 3. Material crack 4, shrinkage 5. Slage inclusion; 6, microporous pore; 7, Insufficient tempering; 8, excessive stress.
If you are avoided the above 8 points the quality of the bearing can be greatly improved.
