Friendly Reminder:
Normally, there may be 1 or 2 missing balls on each side. The carriage block may get slightly stuck when it's full of balls because the balls on each side need some space to run properly.
If the guide rail feels a bit stiff, please apply some lubricant, and it will run smoothly.
The length mentioned on this page refers to the length of the rail, not the stroke of the slider.
The guide rail may have a tolerance of 0.025mm or -0.025mm, but this does not affect its normal use.
