Consult Our Application EngineersHow to Select the Right Mini Guide Rail
Professional guidance for optimal component selection
Load Requirement Analysis
Calculate total payload including workpiece, tooling, and dynamic forces. Consider radial, reverse radial, and moment loads. Apply appropriate safety factors (typically 1.5-3) based on operating conditions and duty cycle requirements.
Stroke & Speed Considerations
Determine maximum travel distance and required velocity. Account for acceleration/deceleration zones. Higher speeds demand adequate lubrication and may reduce lifespan. Consider rail length availability and support span requirements.
Preload & Accuracy Selection
Match preload grade to precision needs: Z0 for smooth operation, ZA for moderate precision, ZB for highest rigidity. Higher preload increases stiffness but also friction. Consider positioning resolution and repeatability requirements for your application.
Mounting Space Constraints
Measure available mounting surface dimensions and verify flatness requirements. Choose H-type for maximum rigidity or C-type for compact installations. Ensure adequate clearance for slider movement and maintenance access in your equipment design.

Professional maintenance strategies to maximize service life and performance
Mounting Surface Flatness
Install rails on precision-ground surfaces with flatness tolerance within 0.02mm per 100mm. Surface parallelism between rail mounting positions must not exceed 0.03mm. Poor surface preparation causes uneven load distribution, accelerated wear, and premature failure. Use surface plates or CNC machined bases for critical applications requiring maximum lifespan.
Lubrication Strategy
Apply lithium-based grease (NLGI Grade 2) every 100km of travel or monthly intervals. High-speed applications require synthetic oil lubrication systems with appropriate viscosity ratings. Clean environment operations can extend intervals to 200km. Contaminated environments need protective bellows and frequent relubrication. Proper lubrication reduces friction by 40% and extends L10 lifespan significantly.
Maximum Speed Limits
Respect maximum velocity specifications: MGN7/9 (2m/s), MGN12 (3m/s), MGN15 (4m/s). Exceeding limits causes ball skidding, increased temperature, and rapid raceway wear. High-speed applications demand enhanced lubrication and thermal management. Consider duty cycle and acceleration forces when calculating actual operating speeds for optimal lifespan performance.
Load Distribution Methods
Prevent eccentric loading by maintaining load center alignment with slider centerline. Off-center loads create moment forces that overload ball raceways asymmetrically. Use multiple sliders per rail for heavy or unbalanced loads. Install rails with appropriate spacing to minimize cantilever effects. Proper load distribution prevents premature wear patterns and extends service life by 2-3 times.
