THK NART-R Series Non-Separable Roller Follower

The THK NART-R Series Non-Separable Roller Follower is a compact bearing unit with the inner ring fixed to the side plates. Its spherical outer ring helps accommodate shaft misalignment and reduce biased loading.

The NART-R is available with caged rollers or full rollers. The caged type is suited to higher-speed rotation, while the full-roller type provides higher load capacity. Sealed versions are also available.

Inner diameters range from 5 to 50 mm. Basic dynamic load ratings range from 2.84 to 48.3 kN with a cage and 6.46 to 84.4 kN with full rollers, depending on the model.
