It is optimal as a cam mechanism and guide roller for linear motion!
The roller follower is a compact and highly rigid bearing that incorporates needle rollers inside and is used as a cam mechanism or guide roller for linear motion. The outer ring is designed to rotate while directly contacting the mating surface, allowing it to be thick-walled and capable of withstanding impact loads. For more details, please contact us.

basic information
**Features** The outer ring is equipped with precision cage needle rollers, which prevent skewing, provide excellent rotational performance, and can withstand high-speed rotation. The roller followers come in two types: separable and non-separable. The outer diameter of the outer ring is available in spherical and cylindrical shapes, with the spherical outer ring able to absorb misalignment of the shaft center during installation and help alleviate uneven loading. **Product Lineup** ○ NAST Type (Separable) → This is a separable type that combines a thick-walled outer ring, an inner ring, and precision cage needle rollers. ○ NAST-ZZ Type (Separable, with Side Plates) → This separable type combines side plates on both sides of the inner ring of the NAST type to form a labyrinth seal. ○ RNAST Type (Separable, No Inner Ring) → This is a type of NAST without an inner ring. ○ NART-R Type (Non-Separable) → This is a non-separable type with side plates fixed to the inner ring. The outer ring's outer diameter is processed with a spherical shape to alleviate uneven loading. ○ NURT Type (Multi-Row Cylindrical Roller) → This incorporates cylindrical rollers in multiple rows, allowing for high radial load capacity. ● For more details, please contact us or refer to the catalog.
