The equipment on which the LM Guide is used is vibrating. Are there any measures for suppressing vibration?
A probable cause is insufficient rigidity of the LM Guide or other coupled parts. Verify the rigidity of each part. Improve the rigidity of the LM Guide by changing the preload model (light preload C1, medium preload C0). Decrease the imposed load by widening the block span and rail span or by opting for a higher model number. These are just some of the available measures.
