Tapered roller bearings carry combined loads with high axial capacity in one direction and are mounted in opposed pairs or as matched sets (DF, DB, TDO, TDI). Metric designations follow ISO 355: series 302 (30205 = bore 25 mm), 303 (heavier), 313 (steep angle for high axial load), 320 (light), 322/323 (wide), 329/330/331/332 (low section). Inch bearings are ordered as cone (inner ring with rollers) and cup (outer ring) numbers, e.g. LM 29748/710 or EE 243190/243250, where the two numbers must be paired as listed in the manufacturer tables. Q, J2/Q and CL7C suffixes denote SKF geometry and quality classes. The finder lists the catalogue by bore with one column per series; inch bearings are grouped in their own column.
Set the axial clearance or preload on assembly — tapered bearings are adjustable and the correct setting depends on the application. Cone and cup of different manufacturers should not be mixed within one bearing unless the ISO interchange is confirmed. For wheel and gearbox applications quote the full cone/cup pair.
