This standard specifies the boundary dimensions of four structural types of combined needle roller bearings with thrust ball bearing (hereinafter referred to as combined bearings).
Type NKX 00 - the combined needle roller bearings with thrust ball bearing (see Figure 1);
Type NKX 00 Z - the combined needle roller bearings with thrust ball bearings equipped with casing (see Figure 2);
Type NKX 00+IR - the combined inner ring needle roller bearings with thrust ball bearing (see Figure 3);
Type NKX 00 Z+IR - the combined inner ring needle roller bearings with thrust ball bearings equipped with casing (see Figure 4).
