  Flat Roller FT Type

  THK

  [Features]
  ·The flat roller is made by press-molding a steel plate into an M shape to increase rigidity and reduce weight.
  ·The rollers are held in cage pockets and have a structure that prevents them from falling off.
  ·In addition, since the cage with rollers with a roller diameter of 5 mm or more has a roller support, smooth motion can be obtained without damaging the raceway surface even if the hardness of the raceway surface is low.
  ·These flat rollers are sandwiched between the two rolling surfaces, so as the table moves, they move in the same direction by 1/2 of the table's travel distance.
  · [Large load capacity]Since the rollers are installed with a small pitch, the allowable load is large, and depending on the conditions, it can be used even on the rolling surfaces of castings that have not been quench-hardened. Also, the deflection stiffness of the table is almost the same as that of the sliding surface.
  · [Standardized combination accuracy for 90° V face and plane]It is standardized so that it can be mounted on the most common 90° V-flat sliding surface of the table and saddle narrow guide system of various machines, so it can be used without major design changes.
  · [Lowest friction among roller-type linear motion systems]Since the rollers are held in alignment by a lightweight and rigid cage, there is no mutual friction between the rollers and the skew of the rollers is suppressed. As a result, the coefficient of friction is as small as µ = 0.001 to 0.0025, and stick-slip, which is a problem on sliding surfaces, does not occur.
  · [One-touch cage connection]When incorporating into a large machine, the flat roller can be easily connected on the bed, making assembly easy no matter how long it is.
  ·The rollers are single-rowed and are mainly used on flat surfaces.
  [Applications]
  ·Flat rollers are ideal for large machine tools such as planers, plano millers, and roll grinders, as well as where high precision is required, such as surface grinders, cylindrical grinders, and optical measuring instruments.

  LM Roller LRA Model, LRA-Z Model

  THK

  [Features]
  · The LM roller incorporates a punch roller in the track rail outer circumference which has been precisely machined for rigidity to perform endless circulation secured by the retainer.
  · A central guide is integrated in the central load bearing region of the track base, and the unique structure constantly corrects the skew of the roller, for a smooth motion.
  · Used in the XYZ guide components, precision press ram guides, press mold exchange apparatus, various heavy load conveying devices, etc. of various NC machine tools.

  Precision Linear Pack ER Type

  THK

  Reduced design and assembly costs, long-term stability, lightweight · Compact · Excellent responsiveness at high speeds.
  
  [Features]
  · The ER model is a slide unit that is grind finished after heat treatment with precision molded stainless steel plates
  · The ball rolling motion and sliding structure between the outer rail and the inner V groove where the ball moves in the internal case in this extremely thin and lightweight unit to perform infinite linear motion.
  · Widely used for magnetic disk devices, electronic devices, semiconductor manufacturing devices, medical devices, measuring devices, plotter devices, and copying machines, etc.
  · [Reduced design and assembly costs] Design cost and assembly times can be reduced, and highly accurate linear guidance can be achieved compared to conventional miniature ball bearings used for precision instruments.
  · [Long term stability] Stable performance is obtained for long time periods with the ball circulation type slide unit due to the extremely small coefficient of friction.
  · [Lightweight, compact, high speed response] The outer and inner are composed of minimum thickness stainless steel plates.
  · The light weight allows lower moment of inertia and demonstrates excellent high speed responsiveness

  LM roller LRB/LRB-Z type

  THK

  The LM Roller has a pin-shaped roller built into the outer circumference of a precision-ground rigid raceway base, which is held by a retainer and performs infinite circulating motion.
  [Features]
  ·The LRB type does not require grooving on the mounting surface, reducing the number of processing steps. Mounting brackets SMB type and SE type can be used and fixed with bolts.
  ·The LRB-Z type uses a resin retainer to reduce weight, and the mounting method is the same as the LRB type. In addition, since a seal mounting groove is provided, a special rubber seal with excellent wear resistance and high dust resistance can be easily mounted. Furthermore, high-speed travel of 1 m/s is possible.
