Pack content

Ball Bearing 688Z 8x16x5 - for ACME rod

These bearings can be used with 8mm ACME rod and the Threaded Rod Plate.

  • 688Z Ball Bearing
  • RPM rating 5000-6000
  • 8mm Bore
  • 16mm OD
  • 5mm Width

Nut Block for 8mm Metric Acme Lead Screw

This 8mm Acme Nut Block is a great choice for many projects requiring lead screw linear motion. It serves more than one purpose in that it can be mounted to the bottom of a 3mm plate utilizing M5 nylon insert nuts and 15mm M5 screws or can also be mounted directly to V-Slot utilizing two channels with 15mm M5 low profile screws and two tee nuts.  These mounting choices allow for a host of modular machine applications.  You can mount this block along any length of V-Slot to create your linear motion.


One revolution moves 8mm

Use in conjuntion with the 8mm Metric Lead Screw

8mm Metric Acme Lead Screw.

Select Length

These trapezoidal (metric) lead screws pitch and diameter are a perfect combination of high torque and speed. This screw fits the bill for most machine designs and has become a standard on OpenBuilds.

Equipped a high pitch which provides a quick 8mm translation for every single revolution on the screw.

40mm is added to the length by standard. This is to allow the ACME rod to fit a standard length rail and have some extra mm sticking out and reach a pulley, coupler or other drive components.

It's a great power transmition choice for your build!

  • Tr8*8-2p (4 starts)
  • Lead Screw Diameter ∅ 8 (mm)
  • Pitch 2 (mm)
  • Lead 8 (mm)
  • Stainless Steel
  • Actual Length: 250: 290mm; 500: 540mm; 750: 790mm; 1000: 1040mm; 1500: 1540mm

Please note: Long screws can wobble - but properly mounted with bearings at both ends and one or preferably two ACME nuts on the gantry plates this should not be any problem.

An example steps settings for your control software would be 200 steps per millimeter if you are running the common 1.8 degree steppers and your stepper driver is set to 1/8 step mode.

To calculate different step scenarios for your control software have a look at these handy steps calculators: Here and here

Common setup example


 NOTE: Because this lead has 4 starts with 2mm pitch between each this means the pitch will be 8. So 8 is what you would use for the pitch setting in the steps calculators..

Eccentric Spacer. Length 1/4"

Eccentric Spacers are the perfect solution for creating a pre-load from the V-Wheels to the V-Slot™ rail.


They are added to one side of a set of wheels on a gantry plate.

The eccentrics give an aprox 0.79mm adjustment range allow for a very strong and secure connection between the V rail and wheel.

The Eccentric Spacers comes with a divot on the outside which allows you to know at all times where the smallest part of the cam hole is.

  • Stainless Steel
  • 10mm can size
  • 1/4" can height
  • Rim fits into a 7.12mm hole
  • 5mm Bore

Quantity (1)

Adjustments are made with a 10mm wrench

Lock Collar - 8mm

Shaft Collar, Set Screw Type.  Great for use on ACME threaded rod or smooth shaft. 
8mm Size - Inside Dia 8mm, Outside Dia 14mm, Width 7mm, Steel with Black Oxide Finish
Set screw included (1)

Spacer Block

This is the V-Slot Spacer Block.  It was specially designed to be used in conjunction with the V-Slot Gantry Plate.  

It allows you to raise the V-Slot Gantry Plate up away from the rail 12mm so that you can run transmission components such as a belt drive or threaded rod underneath the V-Slot Gantry Plate. 

  • M5 tapped holes to allow mounting to the V-Slot Gantry Plate.  
  • 3 holes that allow for mounting of full size OpenBuilds Wheels.
