The effect of heat treatment on the material of cross roller bearing

Crossed roller bearings are a kind of bearings that are used more mechanically, especially in industrial machines. Of course, when we use them, we need to have better performance of crossed roller bearings to ensure the performance of crossed roller bearings. For various properties, then we need to perform heat treatment on its processed materials, so why do we need heat treatment? Let’s take a look! 1. Surface residual stress The distribution of surface residual stress of bearing steel after quenching is largely affected by the cooling rate and quenching medium. For the materials used in crossed roller bearings, heating to 840 ℃…
