What are Bearing Steel Grades?

Bearing steel grades are high-carbon alloy steels that are specifically designed and manufactured for use in the production of bearings. These materials must have high hardness, wear resistance, and fatigue strength, as well as excellent dimensional stability and heat resistance to withstand the demanding conditions of bearing applications.

Some of the most common bearing steel grades include:
AISI 52100 (also known as 100Cr6 or SUJ2): This is a high carbon chromium bearing steel that is widely used in the manufacture of bearings, ball bearings, and roller bearings.

ASTM A295 Grade 52100: This is a specification for high-carbon bearing steel that is commonly used in the manufacture of anti-friction bearings.
DIN 17230 100Cr6: This is a German standard for high carbon chromium bearing steel.
JIS G4805 SUJ2: This is a Japanese industrial standard for high carbon chromium bearing steel.
ASTM A485 Grade 1: This is a specification for high hardenability anti-friction bearing steel that is commonly used in the manufacture of bearings.
ASTM A534 Grade 9310H: This is a specification for case-hardening bearing steel that is commonly used in the manufacture of high-stress bearings.
Overall, bearing steel grades are carefully designed and manufactured to meet the stringent requirements of bearing applications, and they are essential for ensuring reliable and long-lasting performance of various mechanical systems.

The bearing steel tubes are usually produced by the following steel grades:
100cr6, GCr15, 52100, JX4211, JX4749, PA11,PA12,
SKF3, SKF3-D, SKF3L, SKF3S, SUJ2, SUJ2S2, ZT-SUS2
G8Cr15, GCr15SiMn, GCr15SiMo, GCr18Mo.
Which are widely used to produce pipe bearings, tube bearings,pipe roller bearings,ball bearing tubes.
