General small bearings can use GCr9, GCr15, and medium-sized bearingsSpherical Plain BearingGCr15 and GCr15SiMn are used, with large bearings using GCr15SiMn, and even larger bearings using carburized bearing steel due to hardenability issues. Generally, it undergoes the following heat treatments: 1. Chromium bearing steel: spheroidization annealing, quenching, and low-temperature tempering. The heat treatment process for other chromium bearing steels is generally the same as GCr15, except for differences in specific process parameters. HK should be a perforated single-sided sealed needle roller bearing, and the stamped outer ring is open at one end during processing (some companies have mature technology and can achieve the required accuracy by directly stamping, while others need to add grinding processing technology to ensure the final processing accuracy). But when the final needle installation is completed, the open end will be rolled up, and the final shape is similar to the short cylindrical bearings of NU and NJ types, which have blocking edges at both ends. So during final assembly, the positioning of the shaft shoulder is not on top of the needle roller, but on the outer side of the edge immediately after the machining surface. Moreover, the shoulder step is generally not a horizontal plane, but a sloping surface that gradually rises from the center to the edge (the step surface in the sectional view is V-shaped, with one side forming an angle of about 15 ° with the horizontal plane)Spherical Plain BearingThe contact part is rounded, which means that the actual contact part with the bearing is the rounded part outside the shoulder step of the shaft.
