MGN7 Miniature Linear Guide Bearing with Carriage Block

Product Overview

In the world of miniature precision machinery, every millimeter of space matters. The MGN7 miniature linear guide bearing is engineered to deliver exceptional rigidity, accuracy, and smooth linear motion within an ultra-compact 7mm rail width envelope. Belonging to the industry-standard MGN series of narrow-type miniature linear guideways, the MGN7 is the definitive choice for applications where space is severely constrained but motion quality cannot be compromised.

Key Features:

• Ultra-Compact
  The MGN7 is one of the smallest profile linear guides available, with a rail width of just 7mm and a total block height of 8mm. This makes it ideal for miniature equipment, handheld devices, and multi-axis systems where every millimeter of space is critical.

• High Rigidity from Four-Point Contact
  The gothic arch geometry provides exceptional rigidity in all load directions, enabling the MGN7 to maintain precision positioning even under complex, multi-directional loading. This is essential for CNC machining, 3D printing, and inspection equipment where deflection directly affects output quality.

• Smooth, Low-Friction Motion
  The precision-ground raceways and recirculating ball design deliver smooth, near-frictionless linear travel with minimal vibration and noise. The MGN7 operates quietly and consistently, even at high traverse speeds.

• Corrosion-Resistant 440C Stainless Steel Option
  For food processing, semiconductor, medical, and cleanroom applications, the MGN7 is available in 440C stainless steel with hardness of 56–62 HRC. This material resists rust and oxidation without compromising load capacity or wear resistance.
