.... Visual Examination of General Physical Features The ball bearings were both of the single-row, deep-groove type with split inner rings and a cage. The cage was made of aluminum bronze. The rings and balls were made of steel, equivalent to 52100 bearing steel. These bearings were mounted side by side...

... Abstract The first step in the hardening of steel is getting it hot enough to form austenite, from which martensite can form upon quenching. Not all steels have the same austenitization requirements, however. High-carbon wear-resistant steels, such as bearing and tool steels, require...

... for controlling the amount of carbon in the final as-quenched martensite. For example, while working with bearing steels, Averbach varied the temperature within the Ac 1 to Ac cm range to control the amount of undissolved carbide, thereby controlling the amount of carbon remaining in the austenite ( Ref 18...

...) are dangerously low for protection from brittle failures. For example, of all the steels used in an automobile, the maximum %C is only 0.4 in all parts except the springs, where %C is 0.6 (often 5160 in the leaf springs and 9260 in the coil springs), and the bearings, where %C is 1 (often 52100).

.... A point to bear in mind is that as the grain size increases, the impact transition temperature increases. The effect of grain size in relation to the impact strength of a plain-carbon steel in the normalized condition is shown in Fig. 5.11 . The same trends apply to case-hardening steels in the blank...

.... This is another idiosyncrasy of plastics. A rule of thumb for plastic plain bearings is 1% (0.010 in. clearance for every inch of shaft diameter). For a 1.000 in. diameter steel shaft, the inside diameter of a plastic plain bearing should be 1.010 in.. The explanation for this is that plastic wear debris...
