Easy to Mount accurately
The LM Guide is capable of self-adjustment so that it can reasonably absorb errors in the parallelism between the twp axes and any difference in levels between the top surfaces. This helps achieve highly accurate, light linear motion.
The end plates are designed to smoothly circulate each row of balls so that low-noise linear motion can be achieved.
Given preload or uneven loads, the balls will not produce any differential slip so that the balls roll and circulate smoothly. This gives the LM Guide excellent wear resistance so that accuracy can be maintained for a long period.
