This listing includes two MGN7H miniature linear rail guide blocks. They are designed for precise, smooth linear motion in compact equipment and are compatible with MGNseries rails in sizes 7 to 15 mm, including MGN7C, MGN7H, MGN9C, MGN9H, MGN12C, MGN12H, MGN15C, and MGN15H. Key benefits Precise, repeatable motion with smooth travel and low friction for reliable positioning in tight spaces. Compact 7 mm block size supports small footprint machines without sacrificing rigidity. Robust metal housing with precision ground bearing surfaces to withstand repeated use in demanding applications. Easy installation with standard mounting patterns for quick integration into existing designs. Supplied as a pair, suitable for dualaxis or parallelaxis configurations and consistent alignment. Key attributes Model: MGN7H block (2 pieces included) Package: 2 pieces (2PCS MGN7H Block) Rail compatibility: compatible with MGN7C/H, MGN9C/H, MGN12C/H, MGN15C/H rails Size class: 7 mm miniature rail family Material: metal housing with precision bearing surfaces designed for durability Functionality: enables smooth, lowfriction linear motion for compact applications Mounting: standard mounting holes suitable for common rail systems Finish and tolerance: precisionfinished components suitable for accurate alignment Applications and use cases Small CNC machines and engraving devices requiring accurate axis motion in a limited space 3D printers or DIY CNC builds for reliable X or Y axis guidance Automation fixtures, inspection stages, or lightduty pickandplace or assembly setups needing precise linear travel Notes on installation and care Ensure proper alignment between the block and corresponding MGNseries rail to maximize performance. Use appropriate mounting hardware and torque to the recommended values for secure seating. Lubricate per the rail and block manufacturer recommendations to maintain smooth operation and extend service life. Periodic inspection of mounting integrity and movement smoothness will help preserve repeatable positioning. This twopiece MGN7H block set provides a compact, durable solution for precise linear motion, compatible with a wide range of MGNseries rails, and suitable for multiple compact automation and manufacturing applications.
