NATR/NATV Yoke Type Track Rollers

The NATR/NATV series are high-performance supported roller bearings designed for heavy radial loads, slight axial loads, and angular misalignment. Featuring either a needle roller and cage assembly (NATR) or full complement needle rollers (NATV), they deliver high rigidity and load-bearing capacity. Constructed from GCr15 bearing steel with hardened raceways for superior wear resistance, these bearings are available with single or double contact seals (PP) to ensure reliable operation in dusty and harsh environments. Widely applied in cam drives, conveyor systems, and machine tool guides, they are ideal for automation equipment and mechanical transmission applications where reliability and longevity are critical.
