Motion Constrained has been operating as a surplus automation dealer for a little over 20 years. Our goal is to source high quality linear motion products at an affordable cost so we can pass these savings on to you. We run an eBay power-seller store with 100% feedback and also offer products our own website so we can give our customers even better deals on hard to source linear motion products.

We are one of the few companies in the United States that offer quick turnaround times on in-stock linear guides custom cut to your specifications. We also include free regular ground shipping on all rail and linear guide orders within the contiguous US. We strive to never sacrifice performance or accuracy and will have your order made to your specifications within 2 business days on actively stocked products. What if we don’t have it in our warehouse? We can special order with extended lead times, see individual product listings for details.

We are proud to operate out of beautiful Colorado and encourage relationships with individuals and businesses in our area. We have a dedicated team of six employees to fulfill your automation needs from multiple warehouses in the northern front range area. We can offer custom length linear guides for most projects the very same day for local businesses. Please contact us for more information.
