The Needle Flat Roller Cage is a limited linear motion guide consisting of high accuracy rollers and very precise cages with low cross sectional height. Since rollers are assembled in a cage with a small pitch distance, load ratings are large and rigidity is high. A single row model and a double row model with a 90° angle are standard and can be used to convert conventional plain guiding parts in machine tools into a rolling guide type, without a large-scale redesign of the bed. Since the high accuracy cage guides the rollers, the frictional resistance is very low without stick-slip, and stable linear motion is obtained.Cages made of synthetic resin are ideal for applications where low noise is required. The rollers are caged securely in a retainer, allowing for easy handling.
