Rolele de conducere sunt ansambluri nedemontabile, cu corpuri de rulare pe unul sau pe două rânduri şi cu inele exterioare deosebit de groase. Aceste lagăre preiau forţe radiale înalte, dar şi forţe axiale din ambele sensuri. Suprafaţa exterioară a inelelor exterioare este cilindrică sau bombată. Variantele cu suprafaţă bombată se folosesc dacă apar dezalinieri faţă de calea de rulare sau dacă trebuiesc evitate supratensiunile de muchie. Rolele de conducere se oferă în varianta cu inel interior cu orificiu, cu inel interior cu pivot, precum şi cu înveliş din plastic la inelul exterior.

Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.
