Title: Shenzhen Hiwin Interchangeable Guide Rails MGN12 MGW12 Wide Guide Rails Miniature Guide Rails

MGN features compact size and lightweight, making it particularly suitable for miniaturized equipment. The slider and rail materials are available in stainless steel and alloy steel. Stainless steel linear guide rails, including sliders, rails, and other metal components such as steel balls and retainers, are all made of stainless steel, offering rust-resistant properties. The Gothic arch four-point contact design allows it to withstand loads from all directions, providing high rigidity and precision. With a ball retainer design, it offers interchangeability within precision tolerances.

MGW (wide) features a widened rail design that significantly enhances moment load capacity and can be used as a single axis. The Gothic arch four-point contact design enables it to withstand loads from various directions with high rigidity. The slider is equipped with a micro retainer wire, ensuring that steel balls do not fall out even when the slider is removed. The rail, slider, and all metal components are made of stainless steel, providing corrosion resistance.

Advantages/Features of Linear Guide Rails:


1. High Positioning Accuracy
When using linear guide rails as linear guidance, the friction method is rolling friction, which not only reduces the friction coefficient to 1/50 of that of sliding guidance but also minimizes the difference between dynamic and static friction. Therefore, during table movement, there is no slipping, enabling micron-level positioning accuracy.

2. Minimal Wear, Maintaining Precision Over Time
Traditional sliding guidance inevitably suffers from poor motion accuracy due to oil backlash and insufficient lubrication during movement, leading to wear on the contact surface of the motion track and severely affecting precision. In contrast, rolling guidance experiences very little wear, allowing the machine to maintain precision over long periods.

3. Suitable for High-Speed Motion and Significantly Reduces Required Drive Power
Due to the very low friction during linear guide rail movement, only minimal power is needed to move the table. This is especially beneficial for tables with frequent reciprocating motion, as it significantly reduces power consumption. Additionally, the low heat generation from friction makes it suitable for high-speed operation.

4. Capable of Simultaneously Withstanding Loads in All Directions
Thanks to the unique constrained structure design of linear guide rails, they can simultaneously withstand loads in upward, downward, left, and right directions. Unlike sliding guidance, which has limited capacity for lateral loads in the parallel contact surface direction and can easily cause poor machine accuracy, linear guide rails excel in this aspect.

5. Easy Assembly and Interchangeability
During assembly, simply mill or grind the mounting surface of the rail on the table, and follow the recommended steps to fix the rail and slider to the machine with specified torque to achieve high precision. Traditional sliding guidance requires scraping of the motion track, which is time-consuming and labor-intensive. If machine accuracy deteriorates, scraping must be repeated. Linear guide rails are interchangeable, allowing replacement of sliders, rails, or even the entire linear guide assembly to restore high-precision guidance.

6. Simple Lubrication Structure
If sliding guidance is inadequately lubricated, direct metal-to-metal friction can wear out the table. Ensuring sufficient lubrication for sliding guidance is challenging and requires drilling holes in appropriate locations on the table for oil supply. Linear guide rails, however, come with oil nozzles on the sliders, allowing direct grease injection via a grease gun or connection to an oil supply line with specialized fittings for automatic lubrication.
