    Naaldrollagers is laers met silindriese rollers wat klein in deursnee is relatief tot hul lengte. Die gewysigde rol-/loopbaanprofiel voorkom spanningspieke om die laer se lewensduur te verleng. Naaldrollagers is in baie verskillende ontwerpe, reekse en in 'n wye reeks groottes beskikbaar, wat hulle geskik maak vir 'n wye verskeidenheid bedryfstoestande en toepassings.
