Full-Ball LM Guide Separate Type Model GSR
Since this LM Guide model has a large self-adjustment capability, it is optimal for locations where it is difficult to secure mounting accuracy and for applications such as general industrial machines.
Size : 15,20,25,30,35

Features
Structure and Features

Balls roll in two rows of raceways precision-ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate. Since retainer plates hold the balls, they do not fall off.
As the top face of the LM block is inclined, a clearance is eliminated and an appropriate preload is applied simply by securing the LM block with mounting bolts.
Model GSR has a special contact structure using circular-arc grooves. This increases self-adjusting capability and makes GSR an optimal model for places associated with difficulty establishing high accuracy and for general industrial machinery.
* Model GSR cannot be used in single-axis applications.
Interchangeability
Both the LM block and LM rail are interchangeable and can be stored separately. Therefore, it is possible to store a long-size LM rail and cut it to a desired length before using it.
Compact
Since model GSR has a low center of gravity structure with a low overall height, the machine can be downsized.
Capable of Receiving a Load in any Direction
The ball contact angle is designed so that this model can receive a load in any direction. As a result, it can be used in places where a reverse radial load, lateral load or a moment in any direction is applied.
Example of Clearance Adjustment
By providing a shoulder maybe on the side face of each LM block and pressing either LM block with a bolt, a preload is applied and the rigidity is increased.
