Understanding the engineering behind reliable positioning and vibration control in precision linear motion systems
Integrated Lock & Slide System
- Dual-Function Carriage Design: The SGR lock module seamlessly integrates with the standard ball carriage, allowing free linear motion when released and instant rigid locking when engaged, without adding bulk to your assembly
- Synchronized Brake Mechanism: Mechanical clamping bars apply uniform pressure across the rail width when activated, distributing holding force evenly to prevent rail distortion while maintaining perfect alignment
- Vibration Dampening Structure: Bilateral support brackets absorb shock loads and resonance frequencies, reducing positioning drift by 85% compared to standard rails during high-acceleration movements
- Precision Ball Recirculation: Optimized ball groove geometry ensures smooth rolling contact during motion and stable load distribution during lock, preventing premature wear at contact points
Ideal Application Scenarios:
Perfect for automated assembly lines requiring position holding during pick-and-place cycles, compact precision inspection equipment demanding vibration-free measurement zones, small XYZ positioning platforms in laboratory automation, and medical diagnostic devices needing silent operation with zero drift

Speak with an EngineerWhy SGR Lock Outperforms Standard Guide Rails
Each feature directly addresses the pain points that compromise your equipment's performance, offering measurable improvements where it matters most
High-Strength Lock Eliminates Carriage Slippage
Reinforced clamping mechanism generates 1200N holding force per carriage, completely preventing unintended movement under external vibration or rapid deceleration, solving your loosening problems permanently
Bilateral Support Minimizes Vibration
Symmetrical mounting structure distributes dynamic loads across dual support points, reducing operational vibration amplitude by 75% and eliminating the rattling noise that disrupts precision work environments
Precision-Ground Rails Prevent Path Deviation
CNC grinding achieves straightness tolerance within 3μm per 300mm, maintaining perfect trajectory even at 2m/s speeds, ensuring your cutting tools and assembly heads hit their marks consistently
High-Wear Materials Extend Service Life
Chromium steel balls with ceramic coating resist pitting corrosion and surface fatigue, delivering 3x longer operational life than standard components and reducing replacement frequency from quarterly to yearly intervals
Multi-Model Customization Ensures Perfect Fit
Flexible configuration options covering 15-35mm widths with adjustable carriage spacing and custom rail lengths eliminate compatibility headaches, allowing drop-in replacement for virtually any automation platform

How to Select the Right Model for Your Application
Start by calculating your total moving mass and required positioning accuracy. For loads under 50kg with precision needs of ±0.01mm, SGR15L or SGR20L models provide optimal cost-performance. Medium loads between 50-150kg benefit from SGR25L's balanced capacity. Heavy-duty applications exceeding 150kg or requiring vibration resistance in harsh environments should specify SGR30L or SGR35L with reinforced lock modules. Consider stroke length carefully—we recommend rail length at least 200mm longer than maximum travel distance to accommodate mounting brackets and ensure full carriage support throughout the range. Our engineering team can verify your load calculations and recommend appropriate safety factors based on your duty cycle, acceleration profiles, and environmental conditions. Contact us with your CAD drawings or application parameters for a detailed selection analysis within 24 hours.
