THK track rollers are specialised components designed for linear motion applications. They are known for their high precision, reliability, and ability to handle heavy loads and high speeds. They are engineered to minimise friction and designed for a straightforward easy installation. They are available in various sizes, shapes, and mounting configurations to meet different applications needs.
Roller Followers:
Structure: Compact bearings featuring a high-rigidity shaft with built-in needle bearings. They are ideal for guiding cam mechanisms and linear motion.
Models:
NAST: Separable type combining a thick-wall outer ring, inner ring, and needle rollers with a precision cage.
RNAST: Similar to NAST but without an inner ring.
NART: Non-separable type with a spherical outer ring, suitable for applications requiring high rigidity.
Features: Available in standard types, types without inner rings, and types with side plates. Some models come with seals to prevent contamination
Applications: Widely used in cam mechanisms of automatic machines, conveyors, and various industrial equipment
Flat Rollers (LM Rollers):
Structure: Compact linear guides with high load performance, featuring a mallet-type roller capable of infinite circular motion.
Models:
FT (Flat Surface Type): Single row of rollers designed for flat surfaces.
FTW (V Groove Type): Multiple rows of rollers arranged at 90° angles, suitable for V-shaped tracks.
Features: Provide high positioning accuracy, repeatability, and rigidity.
Applications: Ideal for machines requiring precise linear motion and high load capacity.
