Sugatsune America’s multi-roller linear guide rail MLGX25-400S provides a compact, precision-engineered motion platform for automated machinery, robotics, medical equipment, analytical systems, food equipment, or kiosks. Like all available lengths, the 400 mm rail is made of 304-grade stainless steel and uniquely shaped to provide the pre-loaded MLGX25 carriage with a track that delivers smooth, consistent movement along its entire length. Each guide rail is 1” (25 mm) wide and is 3/8“ (9.7 mm) tall, with the MLGX25-400S being 15-¾” (400 mm) in length.
The MLGX system features a carriage designed with Sugatsune’s proprietary Dual-X design, which ensures consistent rail contact and smooth movement in multiple mounting orientations. Combined with this MLGX-25C roller carriage, the rail supports up to 120 N (27 lb.) of force and resists binding under rotational moments.
With consistent automation equipment hardware performance and a system life of over 100 km, it works well with motor-driven assemblies. Engineers comparing rail lengths and configurations can review the complete MLGX Multi-Roller Linear Guide series for additional system options.
MLGX Guide Block Integration and Mounting
The MLGX25-400S rail is designed for use with the MLGX-25C-8 Multi-Roller Linear Guide Block. To ensure smooth operation and zero play, the guide block features a factory preload and supports multi-block layouts on a single track.
Order rails and guide blocks separately. The system has also passed 500,000-cycle precision-performance testing. Installation requires M4 hexagon socket bolts with a head diameter of 7.6 mm or less and a head height of 2.2 mm or less. Mounting bolts must be sourced separately, as they are not included. The rail is RoHS 3 compliant.
Sugatsune provides downloadable 2D and 3D CAD files so engineers can verify mounting geometry, rail position, guide-block travel, and equipment clearances before fabrication.

FAQs
What load can the MLGX25-400S system accommodate?
This rail, along with the MLGX-25C-8 carriage, can support loads up to 120 N, or approximately 27 lb. Because of the carriage’s Dual-X design, you can apply this load horizontally or vertically. The roller geometry also compensates for changes in moment forces to ensure uninterrupted travel along the rail.
Is the MLGX-25C-8 guide block included with the 400 mm rail?
No. The MLGX25-400S rail and MLGX-25C-8 guide block are ordered separately. Please ensure you include the SKU MLGX-25C-8 for the carriage, and then choose the length of the rail to fit your application. Available lengths: 200 mm, 300 mm, 400 mm, 600 mm, 800 mm, 1,000 mm, and 1,200 mm.
Can the MLGX25-400S rails be used with other available carriages or guide blocks?
No, the MLGX25-400S rails are hexagonal and designed to accept the wheel designs of the MLGX25-C specifically.
