The SCHNEEBERGER BMW W 35-A-G2-V2 linear guide features a 35mm rail width with industrial-grade A-type sealing for extreme contamination environments.Engineered for
mining,steel mills,and wood processing,it delivers 55.6kN static load capacity and±0.002mm repeatability using G2 precision geometry and V2 rigidity enhancements.Operators
frequently search for high-load dust-proof rails,mining equipment guides,and replacement carriages.

Key Features&Advantages
1.Heavy-Duty Sealing(A-Type)
Triple-lip seals and integrated scrapers block wood chips,metal shavings,and silica dust.Field tests show 3x longer life than standard seals in quarry conveyors.
2.V2 High-Rigidity Design
Reinforced end caps and thicker rail walls increase moment capacity by 25%.Critical for vibrating screens handling 50-ton/hour loads.
3.G2 Friction Reduction
Asymmetric ball grooves cut drag force by 18%at 2m/s speeds.Reduces energy costs in automated lumber handling systems.
Industrial Applications
Mining Crushers:Withstands rock dust at 10g/m³concentrations
Steel Rolling Mills:Endures scale accumulation and 800°C radiant heat
Wood CNC Routers:Immune to resin buildup and chip infiltration
Installation&Maintenance
Mounting Procedure:
Degrease surfaces with alkaline cleaners(pH 9-11).
Align rails within±0.015mm/m using SCHNEEBERGER’s DUST-ALIGN jig.
Torque M10 bolts to 32 Nm in cross pattern.
Maintenance Protocol:
Apply Kluberplex BEM 41-132 grease every 500 hours
Clean wipers monthly with soft brushes
Replace scrapers after 250km travel
Critical Warnings:
Never expose to water jets(seals aren’t waterproof)
Limit impact shocks to<10%of static load
Ground equipment near welding stations
Q1:How does this handle explosive dust environments?
Combine with SCHNEEBERGER’s ATEX kit(order code EX-35A).Use conductive grease to prevent static discharge.Maintain surface resistance below 10<sup>6</sup>
ohms.Never install near ignition sources.
Q2:What lubrication works in high-sawdust woodworking?
Choose tacky EP2 grease like Mobilith SHC 460.Its fibrous structure traps particles.Apply via zerk fittings every 200 operating hours.Avoid low-viscosity oils-they attract dust.
Q3:Can I use these on vibrating screens with 5g acceleration?
Yes,when mounted with SCHNEEBERGER’s VS-35 dampers.Limit stroke to±3mm at 25Hz.Secure cables with strain relief clamps.Check bolt torque weekly.
Q4:How to clean resin-clogged carriages?
Soak in methyl ethyl ketone(MEK)for 20 minutes.Scrape gently with brass tools.Rinse with compressed air at 0.3MPa max.Replace seals if hardened.
Q5:What causes premature wiper detachment?
Excessive side loads above 15kN shear adhesive.Install lateral guides on long strokes.Check frame rigidity-deflection>0.1mm/m strains seals.
Q6:Are these compatible with magnetic encoders?
Only non-magnetic versions(suffix-NM).Keep scales 2mm from rail surfaces.Shielding required near VFD cables above 10A current.
Q7:How to retrofit older conveyors without frame machining?
Use SCHNEEBERGER’s ADAPT-35 shim system.Compensates for±1.5mm misalignment.Always recalibrate encoder references post-installation.
Q8:What’s the temperature limit near foundry equipment?
Install thermal shields for ambient above 80°C.Localized radiant heat must stay below 120°C.Use infrared thermometers for spot checks.
Q9:Can I submerge these in coolant sumps?
Not recommended.A-seals aren’t liquid-tight.For sump applications,specify IP67-rated W 35-S-G2-V2 models with submersible seals.
Q10:How to calculate service life under 30-ton loads?
Use SCHNEEBERGER’s LifeCalc Pro with contamination factor 5.Expect 40,000 hours at 0.5m/s.Monitor vibration-replace at 7mm/s RMS.
