34.70mm(1.366142"), Metal Bearing Steel Ball For Ball Bearing, G28
Introduction
Surface Qualities
Surface Roughness: Surface roughness consists of all those irregularities which form surface relief and which are conventionally defined within the area where deviations of form and waviness are eliminated.
Waviness: The more widely spaced circumferential component of surface texture.
Hardness
Our modern heat treating facilities, complete with controlled atmosphere and temperature, this enables us to maintain the Rockwell hardness within the standard range during any production process and reach any specific hardness specified by the customer. AISI E52100 Chrome Steel Balls are made with a through hardness of HRC 60 to 67, depending on requirements.
Application field
Gcr15 bearing steel balls are widely used in high-speed and low-noise bearings, bicycles, motorcycles, automobiles, slide rails, general-purpose balls, luggage, and electronic industries, and can also be used to grind other media.
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.
