Full-Ball LM Guide Separate Type Model GSR-R
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.

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-R is based on model GSR, but has rack teeth on the LM rail. This facilitates the design and assembly of drive mechanisms.
* Model GSR-R cannot be used in single-axis applications.
Reduced Machining and Assembly Costs
The single-piece structure integrating the LM rail (linear guide) and rack (drive) reduces labor and time for machining the rack mounting surface and assembling and adjusting the guide system, thus to achieve significant cost reduction.
Easy Designing
The travel distance per turn of the pinion is specified by the integer value. This makes it easy to calculate the travel distance per pulse when the LM Guide is used in combination with a stepping motor or servomotor.
Space Saving
Since the rail has a rack, the machine size can be reduced.
Long Stroke
The end faces of the LM rail are machined for jointed use. To obtain a long stroke, simply joint LM rails of the standard length.
High Durability
The rack tooth has a width equal to the LM rail height, the rack uses high-grade steel with proven performance and the tooth surface are heat-treated, thereby to ensure high durability.
