     Crossed-roller bearings that use cylinder-shaped rollers are more accurate and rigid mechanical linear components. Also known as crossed-roller slides, in these mechanisms, cylindrical rollers are sandwiched between two parallel guides called the table and bed. Here, the rollers nest in V-grooved raceways ground out of the guides, and crisscross at 90° angles.

     The rollers make lines of contact that are broader than a ball bearing's point of contact. In addition, most rollers do not recirculate, so their motion is smoother than that of designs with recirculating balls. Deflection under load is reduced and rigidity increased; consistent (slip-free) contact between carriage and base also reduces wear.
