Tapered roller bearings muaj plaub yam sib koom ua ke: lub khob hliav qab (puab lub nplhaib), lub khob (ntiv nplhaib sab nraud), tapered rollers (cov ntsiab lus dov) thiab lub tawb (cov menyuam retainer). Metric series nruab nrab- thiab ntxhab-lub kaum sab xis tapered cov menyuam bearings siv lub kaum sab xis code "C" los yog "D" raws li nram qab no tus naj npawb, thaum tsis muaj code yog siv nrog ib txwm-lub kaum sab xis bearings. Nruab nrab-lub kaum sab xis tapered cov menyuam bearings feem ntau yog siv rau lub pinion shafts ntawm txawv gears nyob rau hauv tsheb.
