Key Features&Advantages
Nanometer Precision
G2 preload minimizes deflection under load,critical for laser cutting and optical alignment.Four-row ball bearings reduce vibration by 40%compared to standard guides.
Zero Maintenance Design
V2 seals block contaminants like dust and coolants.Corrosion-resistant steel withstands harsh environments,including cleanrooms and chemical labs.
Space Optimization
Compact profile saves 30%installation space.Pre-drilled mounting holes enable tool-free assembly,cutting deployment time by 50%.
Industrial Applications
Semiconductor:Wafer handling robots(ISO Class 1 cleanrooms).
Medical:MRI component positioning and surgical robots.
Automation:3D printing beds and CNC tool changers.
Metrology:CMM arms requiring±1μm accuracy.
Installation Guidelines
Surface Prep
Ensure mounting surface flatness≤0.02 mm/m.Use SCHNEEBERGER reference rails(Art.No.100.25)for alignment.
Torque Settings
Tighten M6 bolts to 10 N·m in cross-sequence.Over-torqueing distorts rail geometry.
Lubrication
Pre-greased for life.For high-speed apps(>5 m/s),add Kluber Staburags NBU 12 every 10,000 km.
Critical Notes
⚠️Avoid Thermal Warping
Install away from heat sources>80°C.Thermal expansion coefficient:10.5μm/m·K.
⚠️Contaminant Protection
Use SKF/TTO housing wipers in dusty environments.Replace seals biannually in wet conditions.
Top 10 Google FAQs
Q1:What distinguishes G2 preload from other classes?
G2 preload delivers 8-10%axial rigidity increase over standard G1,eliminating micro-movement in high-torque applications.It balances friction and precision for CNC spindles.
Avoid G3 for high-speed uses due to heat buildup.
Q2:Can MR W 25-A-G2-V2 handle vacuum environments?
Yes,with optional vacuum-compatible grease(Krytox GPL 227).Outgassing rates below 10⁻⁶Torr·L/s.Tested in SEM chambers at 10⁻⁸mbar.Always specify"V2"suffix for
vacuum-ready seals.
Q3:How does V2 sealing outperform traditional wipers?
V2’s triple-lip design reduces particle ingress by 99.7%per ISO 16889.Integrated scrapers eject chips>50μm.Combine with Teflon-coated balls to prevent cold welding in
vacuums.
Q4:What maintenance intervals apply to medical applications?
Sterilize with gamma radiation(<50 kGy).Relubricate every 2 years or 15,000 km.Use FDA-grade lubricants(e.g.,Super Lube®51004).Never disassemble in sterile fields.
Q5:Is re-grinding possible after rail wear?
No.Hardened steel(60 HRC)prohibits regrinding.Replace carriages once backlash exceeds 5μm.Monitor via SCHNEEBERGER’s OptiCheck diagnostic tool.
Q6:What’s the maximum speed for micron-level accuracy?
Sustain 3 m/s with±0.005 mm accuracy.Beyond 5 m/s,use water cooling jackets(accessory#MR-COOL-25).Acceleration tolerance:50 m/s².
Q7:How to troubleshoot abnormal noise?
Inspect seal damage first(90%of cases).Check for:
Insufficient lubrication(add NBU 12).
Particle contamination(flush with isopropyl alcohol).
Misalignment(re-measure flatness).
Q8:Are aluminum rails compatible?
Only with SCHNEEBERGER’s MR-W-AL adapters.Thermal expansion mismatch requires temperature control±2°C.Anodizing mandatory for corrosion resistance.
Q9:Can I retrofit older MR series with V2 seals?
Yes.Order seal kit#MR-V2-UPG.Requires carriage disassembly and precision press tools.Not recommended for non-certified technicians.
Q10:What’s the lifespan under 24/7 operation?
Calculated L10 life:25,000 km at 5 kN load.Extend to 40,000 km with monthly NBU 12 replenishment.Monitor vibration spectra monthly for early wear detection.
