1. rolos cilíndricos estão disponíveis em muitos projetos, série de dimensão e tamanhos. A maioria é rolamentos de linha única com uma gaiola. Rolamentos duplos e carreiras de complemento total (sem gaiola) completam a variedade padrão para engenharia geral. Rolamentos com gaiola podem acomodar cargas radiais pesadas e operar em altas velocidades. Complemento rolamentos são adequados para cargas radiais muito pesadas em velocidades moderadas.
2. a única linha de rolamentos de rolos cilíndricos podem acomodar cargas radiais pesadas e altas velocidades. São fabricados em vários modelos diferentes, a principal diferença é que na configuração de flanges. Os mais populares são os projetos do NU, N, NJ e NUP.
3. aplicações:
Motor elétrico, transmissão automotiva, industrial, duas carreiras de rolos cilíndricos rolamentos são muito utilizados para os eixos de máquinas-ferramentas
