Mobiltac™ 375 NC — Heavy-Duty Open Gear Lubricant for Marine & Mining
Mobiltac 375 NC is ExxonMobil's extra high performance, non-leaded, diluent-type open gear lubricant — engineered for the most demanding marine deck machinery, offshore equipment and high-temperature mining open gear applications. Available through Orbit Industrial as an authorised Mobil distributor.
The non-chlorinated volatile solvent carrier ensures fluidity during application even at low temperatures. Once applied, the diluent evaporates and the lubricant forms a flexible, adhesive, high-strength film that adheres strongly to gear teeth and machine elements — resisting throw-off and providing continuous boundary lubrication throughout the service life of the equipment.
Why Mobiltac NC Over Older Open Gear Technologies
Mobiltac NC represents a significant advance over earlier diluent-type open gear lubricants — providing improved environmental performance (non-leaded, non-chlorinated) alongside better protection under boundary lubrication conditions, better water washing resistance and easier cold-temperature application. It will not harden, chip or flake in cold weather, is self-healing and does not form hard-packed buildup in gear-tooth roots.
Features & Benefits
| Feature | Advantage & Benefit |
|---|---|
| Excellent protection under boundary lubrication conditions | Less equipment wear and breakdown — lower replacement, downtime and maintenance costs |
| Excellent low-temperature pumpability | Easy start-up at low ambient temperatures — avoids cost of preheating |
| Excellent resistance to water washing | Maintains superb protection in wet marine environments — less unanticipated downtime |
| Minimal throw-off and dripping | Less product waste — lower ongoing lubricant cost |
| No chipping or flaking at low temperatures | Maintains protective lubricating film throughout cold-weather operations |
| Easy clean-up with conventional solvents | Improved safety and reduced maintenance costs during servicing |
Product Data Sheet
Recommended Applications — Mobiltac 375 NC
Mobiltac 375 NC, containing a high-viscosity base oil (KV 5,000 cSt @ 40°C diluted), is recommended for the lubrication of highly loaded open gears operating at elevated temperatures — including ring gears on cement kilns, large gears on ore-processing mills, and marine deck machinery under heavy continuous load. Minimum operating temperature: -1°C. Maximum operating temperature: 121°C.
Marine & Offshore Applications
- Marine deck crane open gear systems
- Anchor handling and mooring winch gearing
- Offshore platform deck machinery — highly loaded ring and pinion gears
- Vessel cargo crane open gear systems
- FPSO and offshore support vessel deck equipment
- Marine propulsion auxiliary open gear drives
Mining & Industrial Applications
- Cement kiln ring gears — high temperature, heavy load
- Ore processing mill gears
- Mine and quarry draglines and shovels
- Racks and pinions, swing gears, booms and sticks
- Open gear drives in mining and mineral processing operations
