Ball bearings for aerospace applications encompass radial and angular-contact configurations manufactured to ABEC or ISO precision grades, utilising through-hardened 52100 chrome steel or 440C stainless steel races and rolling elements, with retainers in PEEK, phenolic, or aluminium alloy; they are produced via grinding, honing, and superfinishing processes to meet the dimensional and surface-finish tolerances demanded by flight-critical rotating assemblies.
