Vickers Oils HYDROX BIO 100 sterntube oil

As an ISO VG 100, HYDROX BIO 100 is the viscosity grade generally recommended by bearing and seal suppliers for regular operation in the sterntube. The lubricant is an EAL (Environmentally Acceptable Lubricant), biodegradable, VGP-approved, and class-approved, and can also be used in certain stabilizer systems and CPP hubs. Applications • Regular lubrication of sterntubes • Certain stabilizer bearings • CPP hubs (controllable pitch propeller). Benefits • Verified lubrication even at high water content. • Protects bearings against corrosion. • Excellent wear protection. • Emulsifies ingress of seawater or freshwater into a stable emulsion, reducing the risk of free water and maintaining lubrication. • Compatible with commonly used metals. • Biodegradable (>60% in 28-day OECD 301B and OECD 306 tests) and assessed as non-toxic in the marine environment. • Approved by leading OEM manufacturers: KEMEL, SKF Marine, Wärtsilä, and others. Technical Specifications Typical viscosity (cSt @40°C): 100 Viscosity index (VI): 187 Density (kg/l @15°C): 0.93 Pour point (°C): < −24 (IP15) Anti-corrosion, SKF Water Emcor: Approved Emulsifiable: Yes VGP-approved: Yes Base oil: Synthetic esters Environmental profile and approvals • Environmentally Adapted Lubricant (EAL) in accordance with the ecological definitions and requirements of the US EPA 2013 Vessel General Permit (VGP). • Tested by classification societies, stability, lubricity, and corrosion protection verified by Lloyd’s Register (both pure oil and emulsion, including 20% water contamination). • SKF Water Emcor test: Approved. • Ecotoxicity: Fish LC50 > 1000 mg/l, Daphnia EC50 >1000 mg/l, Algae EC50 >1000 mg/l. • Shelf life: 3 years in original, unopened Vickers containers when stored away from direct sunlight. • Approved for up to 5 years of service when used with OEM elastomers recommended for EAL. • Formulated for a 5-year service life under normal operating conditions (follow oil condition monitoring). • ISO VG 100 viscosity grade is generally recommended by bearing and seal suppliers for regular operation in the sterntube.
