  Profile rail guideways / carriage dimensions selectable / material selectable / SR

  THK

  A type with a compact structure that has a low cross-section height and is resilient against loads in the radial direction. More advantageous than HSR when incurring loads in the radial direction (longevity, precision, rigidity, etc.).
  
  [Features]
  · Circulates the ball row using the end plate that is assembled in the LM block when the ball rotates the rotating side with four rows that have been precision ground into the LM block and LM rail.
  · The ball will not fall out even if the LM block is removed from the LM rail because it is held by a holding plate.
  · Has a low cross-section height, and the LM block has been designed with a high rigidity, which allows for highly precise and consistent linear motion.
  · A compact type with a low cross-sectional height, which is ideal for horizontal guide parts for ball contact structures that are strong against loads in the radial direction.
  · This is a self-aligning type that can easily absorb error in the level precision and the degree of parallelism for the two shafts, which is capable of highly precise and smooth movements.
  · The retainer part on each of the ball rows can obtain rolling motions with limited sound because of the balls being designed to smoothly circulate using the guiding part on the end plate.
  · It is possible to maintain precision of long periods of time, have excellent abrasion resistance and limited differential slipping even when there is a preload or uneven loads.
  · LM block, LM rail, and LM rail are all compatible with stainless steel.

  Profile rail guideways / wide rail / wide carriage / material selectable / SHW

  THK

  A structure with a wide rail width and low center of gravity. SHS It is advantageous when there are Mc moment requirements and is thin compared with.
  
  [Features]
  · A highly rigid LM guide that is capable of superior high speeds, maintenance-free over long periods of time, and having low noise due to the adoption of a ball retainer.
  · The SHW, which has a structure with a width LM rail width and a low center of gravity, is ideal for use in locations where there are space limitations, and when there are MC moment rigidity requirements.
  · Each of the rail rows has been arranged in an array at a 45° contact angle so that the rated load will be the same for all four directions (radial direction, reverse radial direction, horizontal direction) that act on the LM block, which allows it to be used in any position, and can be used for a wide range of application.
  · The self-aligning capability achieved from the unique circular arched-groove front face combination (DF set) makes it possible to absorb the mounting error even when there is a preload incurred, and it is also capable of obtaining a smooth linear motion at a high accuracy.
  · The ball retainers eliminate the mutual friction between the balls and holds the lubricant oil (agent) to achieve superior low-dust performance.

  Profile rail guideways / wide rail / wide carriage / material selectable / HRW

  THK

  A structure with a wide rail width and low center of gravity. HSR It is advantageous when there are Mc moment requirements and is thin compared with.
  
  [Features]
  · Circulates the ball row using the end plate that is assembled in the LM block when the ball rotates the rotating side with four rows that have been precision ground into the LM block and LM rail.
  · Compact heavy load: A high number of effective balls makes it possible to obtain high rigidity in all directions. Has a wide rail width and can adequately withstand moments with a single shaft.
  There is a high rigidity in the horizontal direction and there is no need to for reinforcement such as horizontal pressing due to large secondary moments being incurred on the rail cross-section.
  · The self-aligning capability achieved from the unique circular arched-groove front face combination (DF set) makes it possible to absorb the mounting error even when there is a preload incurred, and it is also capable of obtaining a smooth linear motion at a high accuracy.

  Profile rail guideways / carriage dimensions selectable / precision / material selectable / SSR

  THK

  Radial type that is strong against loads in the radial direction. More advantageous than SHS when incurring loads in the radial direction (longevity, precision, rigidity, etc.). A stainless steel type not featured with the SHS is also available.
  *When ordering multiple shaft types, input multiples of the number of required shafts as the order quantity.
  (Example) required shafts: 2(-II)⇒ Order quantity: "2, 4, 6..."
  Required shafts: 3 3(-III)⇒ Order quantity: "3, 6, 9..."

  All Ball LM Guide, World Standard, HSR-M1 Type for High Temperature

  THK

  High temperature specifications that can be used in maximum temperatures of 150°C, and the grease can also be used in high temperature environments. Has low rolling resistance fluctuation in response to changes in temperature and a dimension consistency treatment has been applied, which has provided excellent dimensional consistency.
  
  [Features]
  · Circulates the ball row using the end plate that is assembled in the LM block when the ball rotates the rotating side with four rows that have been precision ground into the LM block and LM rail.
  · Each of the rail rows has been positioned at a 45° contact angle so that the rated load will be the same for all four directions (radial direction, reverse radial direction, horizontal direction) that act on the LM block, which allows it to be used from any position.
  · The LM guide for use in high temperatures can be used in even higher temperatures of up to 150°C as a result of using a unique technology for the materials, heat treatment, and lubricant.
  · Can now be used in temperatures of up to 150°C by using stainless steel end rails and end rails that utilize rubber materials for use in high temperatures.
  · A dimensional consistency treatment has been applied to achieve excellent dimensional consistency after applying heat or cooling (may thermally expand under high temperatures).
  · The LM block, LM rail, and balls all use stainless steel with excellent corrosion resistance, which is ideal for use in clean rooms.
  · Uses a grease for use in high temperatures with limited rolling resistance fluctuations resulting from grease even when the temperature fluctuates from a normal temperature to a high temperature.
