View License Agreement Based on the know-how gained from many years of experience in the manufacturing and application of both through-hardened and case-hardened (carburized) tapered roller bearings, a tailor-made selection of material and heat treatment for each application can be offered. In most applications, endurance life or wear resistance, or both, are the decisive parameters. Through-hardened and case-hardened tapered roller bearings perform equally well in such applications, provided the requirements on hardness, microstructure, and surface integrity are fulfilled. If high-dimensional stability is required, through-hardening is advantageous particularly in the austempered modification. For applications requiring high-structural strength in particular with heavy shock loads, carburizing is preferable, if the ratio of case depth and the relevant cross-section is less than about 20%. In applications with extreme hoop stresses, austempering or case hardening are heat treatment methods to be considered. | ||
