Cov kabmob no yog tus cwj pwm los ntawm lawv cov duab cylindrical thiab cov menyuam yaus uas tau teem caij rau ntawm lub axis ntawm kev sib hloov.Cov chais yog coj los ntawm qhov chaw sib tw ntawm cov nplhaib sab hauv thiab sab nrauv, ua rau lawv tuaj yeem tiv taus ob qho tib si radial thiab axial loads.Nrog rau qhov tsim tshwj xeeb no, peb cov cylindrical roller bearings tuaj yeem ua tiav qhov nrawm thiab nrawm nrawm, ua rau lawv zoo tagnrho rau kev siv hauv cov khoom siv hnyav xws li cov cuab yeej siv tshuab, cov cuab yeej siv, thiab cov tshuab tsheb:
1. Ib kab cylindrical cov menyuam bearings: NU, NJ, NUP, N, NF thiab lwm yam.
2. Ob chav kab cylindrical cov menyuam bearings: NN, NNU, NNF, NNCL thiab lwm yam.
