How to distinguish the quality of solid steel balls

- Apr 26, 2019-

Most of the solid steel ball is used in conjunction with the bearing, and its quality directly affects the quality and service life of the bearing. The quality of the solid steel ball can be judged from the aspects of the material, the casting process and the specific shape of the metallographic structure.


The material of the solid steel ball usually has several types such as stainless steel, cast iron, and alloy steel. Different materials have different densities, and the quality of the cast steel balls is different. The casting method of solid steel balls is often used for rolling and forging. Different casting methods have different quality of steel balls. The specific shape of the metallographic structure includes martensite, austenite, bainite, ferrite, etc., which also directly affects the quality of the solid steel ball.


In normal use, in order to ensure its quality and prolong its service life, solid steel balls should not be stacked in the open air, because the steel balls will be affected by the natural environment. Solid steel balls can be affected by changes in ambient temperature; placing a solid steel ball outside can cause serious damage to the steel ball. Therefore, users are reminded to use the correct method for storage when storing. It is forbidden to stack in the open air to avoid unnecessary economic losses and affect the normal production of
