Key Features&Advantages
1.Ultra-High Rigidity:
The V2-series design maximizes contact rigidity,reducing deformation under multi-axis loads.Engineers observe 18%less vibration in CNC milling applications.
2.Advanced Sealing(A-Type):
Triple-lip seals block dust,chips,and coolants.Users report 40%longer service life in metalworking plants versus standard seals.
3.Optimized Rolling Geometry(G2):
Precision-ground raceways distribute load evenly across all balls.This cuts wear rates by 22%in 24/7 semiconductor handlers.
Critical Applications
CNC Machining Centers:Handles Z-axis thrust forces up to 35kN.
Automated Optical Inspection(AOI):Maintains±3μm precision over 10M cycles.
Medical Device Assembly:FDA-compliant materials resist sterilization chemicals.
Installation&Maintenance
Mounting Instructions:
Clean mounting surfaces with isopropyl alcohol(IPA).
Align rails using SCHNEEBERGER’s GRIND-GAGE tool(max.0.01mm/m tolerance).
Torque mounting screws to 12 Nm in crisscross sequence.
Maintenance Tips:
Relubricate every 1,000 operating hours with ISO VG 32 grease.
Inspect seals quarterly for debris ingress.
Avoid alkaline cleaners to prevent seal degradation.
Safety Precautions:
▶️Never exceed static load capacity(35.0 kN).
▶️Use ESD-safe handling in electronics manufacturing.
▶️Isolate from high-frequency welding equipment.
10 Top Google FAQs
Q1:What lubrication suits BMW W 25-A-G2-V2 in food processing?
Use NSF H1-certified greases like Kluber Isoflex NBU 15.Apply sparingly to prevent dripping onto products.Clean rails weekly with food-grade solvents to avoid bacterial
growth.Never mix synthetic and mineral lubricants.
Q2:Can I retrofit older SCHNEEBERGER rails with G2 carriages?
Only if rail width and generation match precisely.G2 carriages require V-series rails for geometry compatibility.Verify batch codes via SCHNEEBERGER’s Retrofit Validation Tool
online.Expect 15%accuracy gains.
Q3:How to diagnose abnormal noise in BMW W 25-A-G2-V2 systems?
High-pitched whines indicate lubrication failure.Grinding suggests contamination ingress.Use a stethoscope to isolate noisy carriages.Replace damaged seals immediately.
Always check rail parallelism first.
Q4:What environmental seals work for wood dust exposure?
A-type seals withstand fine particulates down to 5μm.Combine with SCHNEEBERGER’s DMF-25 adhesive strip for gaps.Monthly compressed air purging(max.0.5 MPa)extends
life by 60%.
Q5:Is water cooling compatible with this linear guide?
Yes,with optional CW-25 coolant jackets.Maintain water purity at ISO 4406 15/13/10.Avoid chlorinated coolants–they corrode ball tracks.Monitor for galvanic corrosion near
aluminum frames.
Q6:What alignment tools ensure peak accuracy?
Use laser interferometers for critical setups.SCHNEEBERGER’s ALIGN-PRO software calculates compensation values.For field work,their OPTI-GAGE kit achieves 0.005mm/m
alignment.
Q7:How does preload affect BMW W 25-A-G2-V2 performance?
P2 preload(medium)balances rigidity and heat generation.Increase to P3 for ultra-high stiffness in grinding machines.Never exceed P4–it accelerates wear exponentially.
Q8:Can I submerge these guides in cutting fluid?
Only with S1 stainless-steel upgrade.Standard models tolerate splashes but not immersion.Specify IP68 seals for sump applications.Check fluid compatibility with
SCHNEEBERGER’s ChemResist database.
Q9:What causes premature waviness wear patterns?
Improper mounting surface flatness(>0.02mm/m)is the primary culprit.Second cause:excessive preload during installation.Always use strain-controlled torque wrenches.
Q10:How to calculate remaining service life?
Input dynamic load,speed,and contamination level into SCHNEEBERGER’s LifeCalc software.In cleanrooms,expect 100,000 km travel.Harsh environments reduce life by 40–60%.
Monitor vibration trends monthly.
