2.G2 Ball Recirculation Design
Precision-ground raceways reduce friction by 18%vs.previous generations.Lowers energy consumption in continuous operation.
3.V2 Structural Reinforcement
20%higher moment rigidity prevents deflection in multi-axis robotic arms.Critical for wafer handling automation.
Industrial Applications
Semiconductor Wet Benches:Resists etchants like HF and KOH.
Pharmaceutical Mixing Tanks:Compliant with FDA 21 CFR§211.65.
Marine Robotics:Endures saltwater immersion in offshore ROVs.
Installation&Maintenance
Mounting Procedure:
Degrease surfaces with pH-neutral cleaners(avoid acetone).
Align rails using SCHNEEBERGER’s LASER-ALIGN kit(±0.005mm/m).
Torque M6 screws to 14 Nm in diagonal sequence.
Maintenance Protocol:
Relubricate quarterly with Kluber FPGH 34-802 grease(NSF H1).
Inspect seal integrity after chemical exposure cycles.
Replace carriage blocks every 500,000 cycles in high-contamination zones.
Critical Warnings:
NEVER use chlorine-based cleaners–degrades plating.
Isolate from galvanic couples(e.g.,aluminum mounts).
Limit lateral impacts to<15%of static load capacity.
10 Top Google FAQs
Q1:How does BMW W 25-C-G2-V2 compare to stainless steel guides?
It offers 30%higher load capacity than SS equivalents at 60%cost savings.Zinc-nickel plating provides equal corrosion resistance without weight penalties.Maintenance intervals
extend by 2x in chemical environments.
Q2:What cleaners safely remove hardened photoresist from rails?
Use EKC 830 photoresist remover at<60°C.Rinse immediately with deionized water.Avoid mechanical scraping–it damages seals.Always wear VOC respirators during cleaning.
Q3:Can I use these guides in Class II Div 1 hazardous areas?
Only with ATEX-certified end seals(order code ES-ATX25).Ground rails to<10Ωresistance.Static-dissipative grease like Molykote PG-65 is mandatory.
Q4:What causes electrolytic corrosion between rail and mounting surface?
Dissimilar metals generate galvanic currents.Use SCHNEEBERGER’s VG-25 insulating strips between rail/steel.Apply anti-seize compound(Loctite 8060)on bolts.
Q5:How to verify plating thickness after installation?
Use handheld XRF analyzers like Olympus Vanta.Minimum 22μm on raceways required.Re-plate if readings drop below 15μm in chemical zones.
Q6:Are these compatible with magnetic encoder systems?
Yes,with non-ferrous versions(suffix-NM).Maintain 1.5mm clearance from magnets.Avoid magnetic scales near MRI equipment.
Q7:What lubrication interval suits high-pressure washdown areas?
Relubricate every 200 operating hours.Grease purge fittings(option PF-25)prevent water ingress.Post-wash re-lubrication is mandatory.
Q8:How to restore accuracy after impact damage?
Replace carriages immediately–irreparable deformation occurs above 20%overload.Check rail flatness with optical parallels.Never hammer components.
Q9:Can I shorten SCHNEEBERGER rails on-site?
Only with diamond-coated saws and SCHNEEBERGER’s CUT-GUIDE kit.Deburr edges to Ra 0.8μm.Re-plate cut ends within 24 hours.
Q10:What’s the lifespan in chlorine gas environments?
Expect 18-24 months at 5ppm concentration.Use supplemental PTFE shields(SH-CL25).Monitor plating monthly–pitting indicates failure.
