How to Finish Hevi-Rail Linear Guides

February 05, 2016 - Rockford, IL  -  Posted by PBC News


PBC Linear®’s Hevi-Rail®, a product in the Cam Roller Technology (CRT) family, is a common solution for industrial strength-handing applications with high load capacities. The natural state of the rail may—prior to any surface treatment—exhibit mill scale build-up and surface rust. If this natural state falls outside of the application requirements, there are treatments which can prevent this:

  • Order rails pre-sandblasted and/or pre-oiled to prevent surface rust and mill scale build-up
  • Purchase rails ready to finish, making it easier to apply a clear zinc plating or paint to the raceways


  • When finishing, it is important to tape off the raceways beforehand to avoid changes in performance
  • For Hevi-Rail with surface rust or mill scale build-up that already exists, sandblasting is the best way to prepare the rails for finishing

To learn more about how to finish Hevi-Rail linear guides, contact an application engineer at or watch the video, Top 5 Design Tips for Hevi-Rail, here.
