HIWIN Rail - Full Length Piece 2000mm (Approx 78") with 2 Guide Blocks
$169.00
HIWIN Linear Rail - per inch (Cut to Order)

Introduction:

These rails conform to Hiwin specifications and are interchangeable with Hiwin manufactured rails.

Description:

For the very best quality and precision for DIY CNC, order HIWIN Spec Linear Guide rail. Ships from USA. Full length or cut to order. Comes with 2 guide blocks when ordered in whole 2000mm sections. Custom cut lengths do not include guide blocks (order separately) .

Note: Maximum single length for 1 piece of HIWIN rail is 2000mm or 78.74 inches.

The function of this rail is to provide a stable guide way that is extremely rigid and allows that axis of movement to maintain it's position across a linear space.

The guide way eliminates or minimizes any sideways or up/down motion and only allows to linear motion.

Generally, these HIWIN rails come as a designation of the width of the rail which in this case is 20mm. The mounting configuration is from the top. The top part of the rail is where the sharper points are located. Mount from the top screw going down. You can use a #8, #10, or M5 screw for mounting the rail.

The measurement from the edge to the first hole is 10mm, if you have the uncut version. The dimension between each hole is 60mm. The thickness of the rail is 17.5mm.

Ordering Info: add desired length in inches to cart (QTY 1 = 1") , if multiple lengths are needed, please contact us to let us know.

These HIWIN linear rails are an industry standard when it comes to high quality, low noise, and superior accuracy. Price listed is per inch.

Skate bearings Step 1 - Linear Slide Bearings
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. If you are looking for great linear slide bearings, see here. Through much of my research on homemade CNC machines, I found that the mechanism to provide linear sliding is simply the use of an angle ("L" shaped piece of metal), bolts or screws (5/16" at 3/4" in length), nuts (5/16") and standard skate bearings (I use ABEC7/608Z). The design is actually very efficient and clutter free. When I say clutter free, I mean that the exhaust of sawdust that the CNC will produce will not clog up these bearings. Collar bearings, or bushing bearings I believe will have the tendency to receive material within the bearing housing creating a binding effect. If you are wondering what a bearing bushing is, imagine a cylindrical tube with little balls housed on the inside surface of the tube. The skate bearing method is like creating a new kind of hybrid inline skates and those skates you used in the 80's with the four wheels (coming back into style, why?!?).
Step 5 - Y-Axis Bearing and Rail Support
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. We are finally to the y-axis. In this video you will see how I built the y-axis linear bearing support and the rail support. First the rail support is similar to the rail support for the z-axis, but wider. This width carries much of the load and the width determines the z-axis length of travel. If you want more z-axis travel, pick a wider y-axis rail support width. In this case, the width to which I'm referring is the short side of the piece. That is... if you made the z-axis travel longer than the length of the y-axis rail, then the width would be more than the length. Did I confuse you yet? I think I confused myself. Well...let's get on with the build.
Step 13: Gantry Y-Axis Rail Support
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. After this video, the gantry will be fully supported with the bottom support and the y-axis serving as the top support. Isn't it nice that all of these parts are intrinsically related. The y-axis rail support will provide two functions. It's primary function is to serve as the rail for the z-axis assembly. The secondary, but really important function is to help support the gantry tighten around the cutting surface x-axis rail support.
