Is Hevi-Rail a better option than Profile Rail in moderate precision applications?
Engineers tasked with designing heavy-duty lift systems are often looking for bearing systems that are capable of muscling heavy loads (over 1,000 lbs) while still offering a practical dose of precision. Often, to fill this requirement, engineers are quick to choose a classic product like profile rail. This choice is fine, but a closer inspection of alternative products like Hevi-Rail cam roller technology reveals that there are more practical and even superior solutions available in the engineer’s toolbox.
In this article, we briefly explore several heavy-duty product options for a real-world, robotic cantilevered lift system involving Z-axis bearings. We then focus on strategies for architecting higher precision into our mightiest cam roller, Hevi-Rail. Once readers understand these simple tips to optimal precision, we can then compare Hevi-Rail's might in motion with profile rail in terms of cost, materials, assembly, maintenance, and robustness.
