TL;DR: Mobil Vactra 2 is an industrial ISO VG 68 way and slide lubricant compliant with DIN 51502 CGLP standards. It serves as a decisive machinery system top-up fluid for horizontal slideways operating under continuous factory production schedules within high-humidity Malaysian industrial processing environments.
Product Identity: Mobil Vactra 2
International Classification: DIN 51502 CGLP slideway lubricant
Fives Cincinnati Suitability Standard: Certified for specifications requiring P47 compliance
Kinematic Viscosity @ 40°C (ASTM D445): 68
ISO Viscosity Grade (VG): Grade 68
Flash Point, Cleveland Open Cup (ASTM D92): 228°C
Pour Point (ASTM D97): -18°C
Copper Strip Corrosion (ASTM D130): Rated 1B for 3 hours at 100°C
FZG Scuffing Load Capacity (ISO 14635-1): Reaches Fail Load Stage 13 under testing criteria A/8.3/90
Slideway Kinematics: Optimized specifically for horizontal slideways on small to medium-size machine tools using combinations of cast iron, steel, and non-metallic way materials.
Auxiliary System Integration: Engineered for dual-purpose operations as a moderate-duty hydraulic fluid and for circulating systems in large machinery loops.
Component Layouts: Formulated for the direct lubrication of ball screws, linear guides, headstocks, and translating screws.
Application Boundaries: Chemical composition is engineered exclusively for horizontal slideways and moderate duty; it faces structural drain-down risks on high-pressure vertical or inclined systems where a higher viscosity profile like an ISO VG 150 or 220 is required.
Stick-Slip Suppression: The performance-balanced additive system provides controlled frictional properties across diverse metal-on-metal and steel-on-polymer surfaces, eliminating stick-slip (the jerky, unpredictable motion caused by friction variances) and chatter to ensure structural machining accuracy.
Aqueous Coolant Separability: Engineered to maximize demulsibility (the chemical separation of oil from water), preventing cross-contamination with water-based metalworking fluids, which minimizes high pH coolant corrosion on precision sliding surfaces and extends fluid batch life.
Adhesive Molecular Film: Possesses localized adhesiveness (the property preventing lubricant from being wiped away by mechanical forces) to maintain a continuous hydrodynamic protective barrier on sliding components despite continuous tropical humidity.
Target Maintenance Profiles: Ideal for plant procurement managers seeking a 208L industrial drum supply or bulk distribution for precision machine tool alignment, workshops standardizing on P47 compliance, and factories running regular tool operations.
Exclusion Profiles: Not suitable for high-pressure vertical machine axes where high drain-down rates occur, nor heavy-duty machine tool gear drive mechanisms demanding high-viscosity configurations.
Logistical Security: Available as ready stock Selangor and Klang Valley distribution lines to eliminate supply chain disruptions for continuous factory production schedules.
Mechanical Isolation: Lock out the machine tool, stop all forced-feed lubricator pumps, and completely drain the old way lubricant from the pump manifolds, distribution lines, and metering valves.
Sump and Way Cleansing: Wipe down the horizontal ways, clear away tramp oil accumulation, and flush the internal circulation loops to remove degraded fluid residues or high-pH aqueous coolant contaminants.
Fluid Inspection: Verify the new fluid supply matches the specified ISO VG 68 grade and DIN 51502 CGLP physical parameters before open container decanting.
Fluid Charging: Introduce Mobil Vactra 2 into the central reservoir or forced-feed lubricator system up to the maximum engineering fill line.
Air Extraction and Bleeding: Cycle the machinery manually at slow travel speeds across the entire bed length while bleeding air from the furthest line splitters to eliminate system micro-cavitation.
Production Ramp-Up: Initiate the full circulation or flood application parameters, verifying uniform oil-film coverage across all steel, cast iron, or polymer way interfaces before resuming full automated machining load schedules.
Cross-Contamination with High-Viscosity Lines: Mixing Mobil Vactra 2 with ISO VG 150 or 220 fluids inside vertical axis lines reduces adhesion performance, triggering structural drain-down and slide stick-slip.
Inadequate Tramp Oil Skimming: Allowing highly contaminated, high-pH metalworking fluid to pool continuously over the slideways overwhelms the chemical separability additives, resulting in localized corrosion and reduced coolant batch lifespans.
Neglecting Low-Temperature Storage Controls: Storing bulk inventory in unventilated areas that drop below the -18°C pour point threshold causes structural wax crystallization, which will restrict flow through precision forced-feed lubricator orifices during cold startups.
Scheduled Waste Compliance: Disposed fluid must be handled strictly as scheduled waste under the Environmental Quality (Scheduled Wastes) Regulations 2005 enforced by the Department of Environment (DOE) Malaysia.
Storage and Containment: Industrial drums must be kept within bunded storage zones to mitigate environmental release into local stormwater networks during tropical downpours.
Personal Protection: Maintain standard industrial handling hygiene; avoid prolonged dermal exposure to prevent skin irritation, and access the Material Safety Data Sheet (MSDS) via official channels for full toxicological breakdowns.
Engineering Verification Data: Complete Technical Data Sheets (TDS) and Safety Data Sheets (SDS) are maintained under strict document control and are available for engineering review and procurement audit upon request.
Q: Can Mobil Vactra 2 be safely utilized as a primary hydraulic fluid in high-pressure manufacturing systems?
A: No. Mobil Vactra 2 is chemically engineered for slideway lubrication and moderate-duty hydraulic systems; high-pressure applications require dedicated anti-wear hydraulic fluids to prevent shear degradation.
Q: How does this formulation prevent the corrosive degradation of precision ways when exposed to high-pH aqueous coolants?
A: The fluid features optimized coolant separability properties that actively reject water-based metalworking fluids, isolating the machine way metals from high-pH chemical exposure.
Q: Is Mobil Vactra 2 qualified for use across alternative non-metallic or polymer way materials?
A: Yes, it is fully optimized for multiple way materials—including steel-on-steel, cast iron, and steel-on-polymer interfaces—to eliminate stick-slip without surface degradation.
