▶LM GUIDE- HSR Types and Features
 

Standard heavey-load types

Type HSR-A

Type HSR-B


The flange of the LM block is provided with tapped holes to enable simple assembly, making it suitable for use in build-up systems.
Four-bolt type 		The LM blocks can be attached to a table from below. For use with a table in which a through hole cannot be drilled.
Four-bolt type

Type HSR-R

Type HSR-CA



The narrowed flange of the LM block is provided with tapped holes, making it convenient for use in build-up systems. Can be used to replace the former type NSR-TBA.
Four-bolt type

 

Type HSR-CB

 

 

Standard ultra-heavy-load types

Type HSR-LA

Type HSR-LB



While the cross-sectional dimensions are the same as for type HSR-A, the LM block is longer. The number of effective balls is greater than in type HSR-A.
Four-bolt type 		While the cross-sectional dimensions are the same as for type HSR-B, the LM block is longer. The number of effective balls is greater than in type HSR-B.
Four-bolt type

Type HSR-LR

Type HSR-HA

While the cross-sectional dimensions are the same as for type HSR-R, the LM block is longer. The number of effective balls is greater than in type HSR-R.
Four-bolt type

HSR-CA형과 동일 단면치수로서 LM블록 전장을 길게 하여 유효 볼수를 증가시킨 초중하중형이다

Type HSR-HB

 

HSR-CB형과 동일 단면치수로서 LM블록 전장을 길게 하여 유효 볼수를 증가시킨 초중하중형 이다.

Miniature four-way equal-load type Heavy-duty four-way equal-load

Type HSR 8/10/12R

Type HSR 100/120/150  HA/HB/HR

This series features the smallest LM Guide models.
As the LM block is slim, it must be fastened in place
using the tapped holes provided on the top surface.		 Can be used for large machine tools and even buildings

 


 

Construction of Model NRS

 

         Balls roll in four rows of a precisely-ground raceway on an LM rail and an LM block.
      The end plate attached to the LM block causes the trains of balls to circulate.
      As the balls are held in place by the retainer plate, they do not fall off if the LM block is removed from the rail
      (except for types HSR 8, 10, and 12).
      The four trains of balls are arranged so that the contact angle is 45°, allowing each train of balls
      to bear an equal rated load in all four directions: radial, reverse-radial, and the two lateral directions.
      This type can therefore be used in any installation direction.
      Moreover, HSR enables the application of a well-balanced preload, making it possible to increase rigidity
      in the four directions while maintaining a low friction coefficient. The low-profile design and
      use of high-rigidity LM blocks provide stable, highly accurate linear motion.
