Product Description

About the Vertical Machine Slide

  1. The slides are manufactured from 6061-T6 aluminum and finished with a black anodized coating.
  2. Leadscrews are precision rolled from steel, and table screws are located under the table, out of the way of chips. Leadscrew backlash is adjustable.
  3. Dovetailed tables and saddles have adjustable gibs to eliminate play.
  4. Handwheels are graduated in .001″ increments on inch slides and in .01 mm increments on metric slides.

Mounting the Vertical Slide

Click on the image for a larger view

The Sherline 8″ vertical slide is mounted utilizing two 1/4-20 holes on the bottom of the base*. The holes are 2.0″ on centers. The base should be mounted so that the table overhangs the edge of the fixture. Travel is approximately 3″ (76.2 mm) or more, depending on how high your fixture is mounted above a parallel surface.

*NOTE: The base must be mounted to overhang what it is mounted on to achieve full travel. On a flat plate mount, the vertical travel will only be about 0.5″ to 1″.

Weight Capacity

Our slides’ weight capacity is about 10 lbs. depending on where the weight is located and how long the table is.

Duty Cycle

Under heavy constant use, the dovetail area of the slide will start to show some wear on the anodize after one year (2080 hours). They are still fully functional at this point, but the anodized coating will begin to wear thin. The dovetail and the screw will last longer if you keep them lubricated with light oil*.

The leadscrews have a rolled thread which is hardened a bit by the rolling process. The backlash nuts are brass. The nut is the softer material, and therefore it is the part that wears out. The backlash nut is adjustable, so it can compensate for the wear until the threads are gone. You should get the same duty cycle (2080 hours) from the backlash nut before it will need to be adjusted or replaced.

*NOTE: Do not use WD40 as a lubricant on these slides. WD40 will remove the anodized coating from these parts!

The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.


Always wear safety glasses when operating machine tools.
