Hiwin is a well-known Taiwanese producer of linear motion components, and their MGN series is widely used. These linear rails are the go-to choice when precision, reliability, and accuracy matter. Let’s break down the details:
MGN9: This rail has a width of 9 mm. The carriages come in two lengths:
MGN12: With a width of 12 mm, the MGN12 rail is another popular choice. Its carriages are available in the following variants:
MGN15: The widest of the bunch, the MGN15 rail measures 15 mm across. Its carriages come in two lengths:
These miniature linear guides are essential for precise movement along all axes, ensuring that the carriage remains stable without tilting or rolling. They use recirculating balls for smooth motion and have tight tolerances to minimize play. While they were once prohibitively expensive, their prices have become more accessible in recent years.
Now, let’s compare these linear rails to other motion systems:
V-Wheels: V-wheels are common in 3D printers and budget laser cutters. They ride on V-shaped grooves of aluminum extrusions. While cost-effective, they require careful tightening and maintenance over time.
Smooth Rods: Smooth rods, often used with linear bearings, tend to have more play compared to linear rails. Their fit is looser, making them less suitable for heavy loads.
