Anti-Backlash Nut Block For ACME Lead Screw TR8x2/TR8x4/TR8x8


SKU: ABNUTBLOCK-TR8*8/4/2 Category: Tags: , , , ,


The Anti-Backlash Nut Block is a great choice for many projects requiring lead screw linear motion.

The pitch and diameter are a perfect combination of high torque and speed. This screw is suitable for most machine designs and has quickly become a standard for builders and makers.

It serves more than one purpose in that it can be mounted to the bottom of a 3mm plate using M5 nylon insert nuts and 15mm M5 screws or can also be mounted directly to V-Slot utilising two channels with 15mm M5 low profile screws and two tee nuts.  These mounting choices allow for a variety of modular machine applications.  You can mount this block along any length of V-Slot to create your linear motion.

To use the the Anti-Backlash Nut Block – Turn the set screw just enough to take out any play in the Nut Block. Then screw the lock nut on the top of the set screw to lock the set screw in place.
