Title: Shenzhen HIWIN Interchangeable Guide Rails Linear Guide MGN15 MGW15 Wide Guide Rails

MGN features a compact and lightweight design, making it particularly suitable for use in miniaturized equipment. The slider and rail materials are available in stainless steel and alloy steel. Stainless steel linear guides, including sliders, rails, and other metal components such as steel balls and retainers, are 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, enabling single-axis use. The Gothic arch four-point contact design can withstand loads from various directions and offers 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 Guides:


1. High Positioning Accuracy
When using linear guides for linear motion, due to their rolling friction mechanism, the friction coefficient is reduced to 1/50 of that of sliding guides, and the difference between dynamic and static friction becomes very small. As a result, there is no slipping during table movement, enabling micron-level positioning accuracy.

2. Minimal Wear, Long-Term Precision Maintenance
Traditional sliding guides inevitably suffer from poor motion accuracy due to oil backlash and insufficient lubrication during movement, leading to wear on the contact surfaces of the motion track and severely affecting precision. In contrast, rolling guides experience very little wear, allowing the machine to maintain precision over extended periods.

3. Suitable for High-Speed Motion and Significant Reduction in Required Drive Power
Due to the very low friction during linear guide movement, only minimal power is needed to drive the table, especially in applications involving frequent reciprocating motion, which can significantly reduce the machine's power consumption. Additionally, the low heat generation from friction makes it suitable for high-speed operation.

4. Capable of Simultaneously Withstanding Loads from All Directions
Thanks to the unique constrained structure design of linear guides, they can simultaneously withstand loads from upward, downward, left, and right directions. Unlike sliding guides, which have limited capacity for lateral loads in the parallel contact surface direction and can easily lead to poor machine motion accuracy.

5. Easy Assembly and Interchangeability
During assembly, simply mill or grind the mounting surface of the guide 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 during processing. Traditional sliding guides require scraping of the motion track, which is labor-intensive and time-consuming. If machine accuracy deteriorates, scraping must be repeated. Linear guides are interchangeable, allowing individual replacement of sliders, rails, or even the entire linear guide set, enabling the machine to regain high-precision guidance.

6. Simple Lubrication Structure
If sliding guides are inadequately lubricated, direct metal-to-metal contact can cause wear on the table. Ensuring sufficient lubrication for sliding guides is challenging and requires drilling holes in appropriate locations on the table for oil supply. Linear guides, however, come with oil nozzles pre-installed on the sliders, allowing direct greasing with a grease gun or connection to an oil supply line via dedicated oil pipe fittings for automatic lubrication using an oil feeder.
