Frequently asked questions
Which shaft size does the LM16UUOP fit?
It fits 16 mm round shafts. Confirm your rod diameter before mounting, since a mismatched shaft will bind or fall out of tolerance.
Is the open type suitable for all axes?
The open design allows side fitting onto a rod or rail through its lengthwise slot. Use the closed-type bushing where side fitting is not needed and maximum rigidity is required.
