Tr8*8 Leadscrew Anti-backlash Nut
Order No.: ABN-TR88
This is a Pitch 2mm, 4 Starts ABN.
Equation: 8mm Lead= 2mm Pitch*4 Starts.
So it is only compatiable with a Tr8*8 Leadscrew, the first 8 of Tr8 means it is for 8mm diameter Leadscrew and the second 8 means the Lead. 8mm Lead means when drive by a stepper driver in Full Step mode, it moves 8mm per revolution.

When combined with our Tr8*8 Leadscrew Anti-backlash Nut our line of threaded shaft stepper motors provide a level of control and stability that belt systems just can not match. True, you do pay more for these motor systems but when being .01 millimeters out means total failure it is worth the price.
New design of anti-backlash nut POM Tr8*2, Tr8*4, Tr8*8, Tr8*12, Tr8*20 are available.
