In 2026, domestic substitution of high-end specialty lubricants has become a hot trend in manufacturing. Industries such as metallurgy, marine, food processing, and construction machinery rely heavily on imported calcium sulfonate greases like NAUTICA for equipment exposed to water immersion, salt spray, high temperatures, and heavy loads — facing pain points including high procurement costs, long lead times, grease washout, and bearing corrosion and coking.
BX-455/G (C5)-WY Calcium Sulfonate Waterproof & Anti-Noise Grease from BaoXing matches imported products in performance, requires zero equipment modification for direct replacement, and delivers equal performance at a controllable cost — a preferred domestic solution for extreme-condition lubrication.
1. Two Real-World Challenges of Imported Calcium Sulfonate Grease Under Extreme Conditions
In hot-rolling mills, marine applications, food washing lines, and outdoor construction machinery, equipment typically faces a combination of seawater immersion, high-pressure washing, acid-alkali salt spray, and high-temperature heavy-load impact.
Conventional greases fall short in such environments: they wash out quickly under water exposure, leading to frequent bearing corrosion failures; under high temperatures they separate oil and carbonize rapidly, demanding frequent re-lubrication that drives up labor and consumable costs.
Many companies turn to imported NAUTICA calcium sulfonate grease to solve these problems, but this brings two new pressures:
High procurement costs that won't come down. Imported specialty greases carry premium prices, and at scale, maintenance material costs steadily eat into company profits.
Unreliable supply. Overseas ordering cycles are long, and supply chain disruptions create stock-out risks that directly threaten continuous production — at odds with the industry's push for cost reduction, efficiency gains, and supply chain self-sufficiency.
Against the backdrop of accelerating domestic substitution of high-end lubricant materials, more and more factories are looking for a domestically produced calcium sulfonate grease that matches imported specifications, drops in directly, and delivers stable supply. That's exactly why BaoXing developed BX-455/G (C5)-WY — formulated to benchmark imported NAUTICA calcium sulfonate grease, with no need to modify any equipment components for direct replacement.
2. Five Hard-Core Performance Advantages for Wet, Heavy-Duty Conditions
BX-455/G (C5)-WY uses a new-generation calcium sulfonate complex soap base combined with refined base oil and multiple functional additives. Key tested indicators benchmark against imported equivalents, with five core strengths that address real on-site pain points:
✅ Superior water washout resistance and long-term rust protection. Water washout loss ≤ 2.0%, with strong grease adhesion — it won't wash off under prolonged seawater immersion or repeated high-pressure rinsing, solving grease washout and metal corrosion on marine hinges and food washing equipment at the root. It also withstands continuous acid-alkali and salt spray exposure.
✅ Stable across a wide temperature range, no coking or carbonization at high heat. Operating temperature range -10°C to 200°C, with a dropping point up to 260°C and oil separation ≤ 5.0% (steel mesh test). Under continuous high-temperature operation of hot-rolling rolls and high-temperature conveyor rollers, it suppresses oil separation, coking, and carbonization — significantly extending lubrication intervals.
✅ High extreme-pressure and anti-wear performance, no grease throw-off under shock loads. Passes high-standard four-ball EP tests; resists grease throw-off under vibration and heavy-load impact. Also passes the copper strip corrosion test, protecting bearings and articulation points across high-load, continuously running equipment.
✅ Eco-friendly formulation, compatible with multiple seal materials. Compliant with EU ROHS and REACH standards. Excellent compatibility with rubber, silicone, PE, and PVC seals — it won't accelerate seal aging or corrosion, reducing seal replacement frequency and cutting maintenance costs.
✅ Excellent low-temperature pumpability — no clogged grease guns in winter. Similar viscosity ≤ 800 Pa·s at -10°C, with outstanding low-temperature flowability. For outdoor construction machinery and low-temperature workshops, grease guns work smoothly in winter with no preheating required.
3. Four Industry Applications, Ready to Replace Imported NAUTICA Grease
The core value of calcium sulfonate grease lies in handling environments where water, heat, salt spray, and heavy loads stack up together. BX-455/G (C5)-WY covers mainstream equipment across multiple industries:
???? Marine & Water EquipmentSuitable for ship steering gears, anchor chains, deck hinges, and offshore machinery — resisting wave washout and seawater salt spray corrosion. A direct replacement for imported marine calcium sulfonate grease.
???? Metallurgy: High-Temperature, Heavy-Duty LinesFor hot-rolling mill roll bearings, continuous casting ladle turntables, moulds, secondary cooling zone rollers, and tension levelers — standing up to heat, cooling water washout, and dust all at once, reducing downtime for re-lubrication.
???? Food & Pharmaceutical Washing LinesIdeal for juice extractors, mixing equipment, washers, and pump waterproof sealing points, with no harmful leaching. If the grease will directly contact food, contact our technical team for a custom food-grade version.
???? Outdoor Construction & Rail TransitFor railway switch bearings, construction vehicle chassis articulation points, and outdoor wind turbine bearings — resisting rain, salt spray, and day-night temperature swings for long-lasting corrosion protection.
4. BaoXing One-Stop Lubrication Support, Solving the Shortcomings of Imported Supply

???????? On-site engineer support: Free on-site condition surveys, hands-on guidance for grease changeover, and a complete customized equipment lubrication plan;
???? Significant cost savings: Domestic production removes the import markup; grease service life is 2–3 times longer than ordinary lithium-based grease, cutting both labor and material costs from frequent re-lubrication and helping manufacturers control operating expenses.
5. Frequently Asked Questions
Q1: Can BX-455/G (C5)-WY directly replace NAUTICA calcium sulfonate grease?A: Both are NLGI Grade 2 calcium sulfonate complex greases, with one-to-one correspondence in waterproofing, high-temperature resistance, rust protection, and EP performance. Application conditions overlap, and no equipment modification is needed — a direct swap.
Q2: Is this grease safe and compliant for food machinery?A: The product holds ROHS and REACH environmental certifications, is chemically stable with no harmful substance leaching, and is suitable for waterproof sealing points on food washing equipment. If the grease will directly contact food, our engineers can formulate a dedicated food-grade version.
