THK NART Roller Follower

The THK NART Roller Follower is a non-separable roller follower designed for smooth and reliable rotary motion. Its inner ring is fixed to the side plates, forming a rigid bearing unit for cam mechanisms and other applications.

The NART Series is available with a cage or full-roller design. The caged type is suitable for high-speed rotation, while the full-roller type is suited to lower-speed rotation and heavier loads. The outer ring is available in a spherical configuration to help reduce the effects of uneven loading.

THK NART Roller Followers are available with 5 to 50 mm inner diameters. Depending on the roller configuration, basic dynamic load ratings range from 2.84 to 84.4 kN, while basic static load ratings range from 1.18 to 200 kN.
