Request Technical ConsultationUnderstanding SGR Linear Guide Construction
Technical knowledge empowers better selection decisions. Learn how each component contributes to precision, load capacity, and longevity so you can specify the optimal configuration for your application.
Core Components Assembly
SGR Linear Guides consist of precision-ground hardened steel rails paired with moving blocks containing recirculating ball bearings. The rail provides the rigid reference surface while blocks enable frictionless motion through four-row ball circulation paths that distribute loads evenly across contact points. Sealing systems protect internal components from contaminants while retaining lubrication for extended service intervals.
Block Type Variations
Choose from standard flange blocks for general applications, compact low-profile designs for space-constrained installations, or extended wide-body blocks for maximum load capacity. Each type features different mounting hole patterns and height configurations to accommodate specific machine design requirements and assembly constraints.
- Standard Flange Type: Balanced load capacity and dimensions
- Low Profile Type: Reduced height for compact machinery
- Wide Body Type: Enhanced moment resistance and stability
Preload Configuration Methods
Preload eliminates internal clearance to achieve precise positioning without play. Light preload suits high-speed applications prioritizing smooth motion, medium preload balances rigidity and smoothness for general automation, while heavy preload provides maximum stiffness for applications demanding positioning accuracy under varying loads and moment forces.
- Z0 (Light): Minimal friction, ideal for high speeds
- ZA (Medium): Standard preload for general use
- ZB (Heavy): Maximum rigidity for precision positioning
Rail Material Standards
High-carbon chromium bearing steel (GCr15 or equivalent AISI 52100) undergoes vacuum heat treatment achieving 58-62 HRC surface hardness for exceptional wear resistance. Precision grinding produces surface finishes below 0.2μm Ra and straightness tolerances within 0.01mm per 300mm length, ensuring consistent motion quality and extended operational life exceeding industry benchmarks.
Load Direction Capabilities
Four-row ball arrangements handle complex multi-directional forces simultaneously. Radial load capacity manages weight perpendicular to motion direction, moment resistance counters tilting forces around block center, and lateral load capacity absorbs side forces during acceleration and deceleration. This multi-directional capability eliminates the need for complex support structures in dynamic applications.
- Vertical Load (C): Primary weight bearing capacity
- Moment Load (M): Resistance to rotational forces
- Lateral Load (C1): Side force absorption capability
Installation Configuration
Proper mounting fundamentals ensure rated performance. Rails require flat, clean surfaces within 0.02mm flatness tolerance across mounting length. Tighten mounting bolts to specified torque values in sequence from center outward to prevent rail distortion. Parallel rail installations demand alignment within 0.03mm over full stroke to avoid binding and premature wear that compromises precision and component life.

Request Engineering SupportHow to Select the Right SGR Model
Making informed selection decisions ensures optimal performance and longevity. Consider these four critical factors to match guide specifications with your application requirements and operating environment.
Speed Requirements
Operating velocity directly impacts guide selection and preload configuration. Higher speeds demand lighter preload to reduce friction heat generation while maintaining smooth motion quality.
- Low Speed (<0.5m/s): Medium or heavy preload for maximum rigidity
- Medium Speed (0.5-2m/s): Light to medium preload balances stiffness and smoothness
- High Speed (>2m/s): Light preload minimizes friction and heat generation
- Consider lubrication system for continuous high-speed operation
Load Capacity Analysis
Accurate load calculation prevents premature failure and ensures rated service life. Account for static weight, dynamic acceleration forces, and moment loads in all directions.
- Light Load (<30% capacity): Standard blocks provide adequate safety margin
- Medium Load (30-60% capacity): Consider dual blocks for improved stability
- Heavy Load (>60% capacity): Select larger rail size or wide-body blocks
- Apply 2-3x safety factor for shock loads and irregular duty cycles
Installation Space
Available mounting space constrains guide and block dimensions. Measure clearances carefully to ensure proper installation and maintenance access without machine redesign.
- Compact Space: Low-profile blocks reduce overall height requirements
- Standard Space: Flange blocks offer balanced dimensions and load capacity
- Unrestricted Space: Wide-body blocks maximize load and moment resistance
- Verify mounting hole patterns match existing machine structure
Operating Environment
Environmental conditions significantly affect guide performance and service life. Select appropriate sealing, materials, and protective features to match exposure conditions.
- Dusty Conditions: Enhanced seals and dust covers protect internal components
- High Temperature (>80°C): Special lubricants and material treatments required
- Corrosive Environment: Stainless steel construction and protective coatings
- Cleanroom Applications: Low-particle-emission designs with compatible lubricants
