Bearing heat treatment includes: normalizing, annealing, quenching and tempering, cold treatment, tempering, quenching, and accessory tempering;
The precision turntable bearings produced by DZE Bearing generally undergo quenching and tempering, tempering stabilization, surface quenching and other heat treatment processes to improve the internal structure; the quenching and tempering hardness is generally HB229-269; the surface quenching hardness is generally HRC56-62°;
Generally suitable for precision turntable bearings, external gear turntable bearings, internal gear turntable bearings, etc.;
DZE Bearing bearing steel heat treatment includes: annealing and quenching, the hardness of bearing steel after quenching is HRC60-65°; generally suitable for RU series cross roller bearings, XSU series cross roller bearings, RB series cross roller bearings, and YRT three-row combined turntable bearings.
