Description

Needle Roller Pin Type and Function

SUJ2 JIS: High carbon chrome bearing steel, this product has a special steel full hard HRC58-61 bearing. The bearings adopt the Japanese SUJ2 and has improved the ability to handle the flat tip, and the mold is high than SKD - 61 (HRC52) 2-3 times all hardware.L.

Production Method

The quality of the bearing steel is very high. Because of its strict requirement, it is necessary to control the number of non-metallic substrates and carbide, the content, volume, size and distribution of sulfur, phosphorus, hydrogen and non-metallic intermediate and carbonates. The size and distribution of bearing steel has a significant impact on the life of the bearing steel. Bearing failure is often caused by expansion of microcracks that occur around large intermediate or carbides.

The main method for producing bearing steel is continuous casting. Refining + Electroslag Re-melting processing to improve the quality of electric furnace bearing steel,small amount of vacuum induction + vacuum self-consuming double vacuum or multiple + vacuum self-consuming process.
