Description
Castrol Molub‑Alloy OG 3710‑0/00 (also referred to as Castrol Molub‑Alloy 3710‑0/00 Mill Lubricant) is formulated specifically for open gear drives in mill environments such as ball mills, rod mills and tube mills found in industries including coal, cement, copper and phosphate processing. It incorporates a blend of synthetic and petroleum oils selected for thermal and chemical stability over a wide temperature range, together with a proprietary mix of Molub‑Alloy lubricating solids that deliver excellent anti‑wear and load‑carrying properties beyond those of conventional lubricants.
The formulation flows readily during film formation yet resists squeeze‑out, enabling it to cling tenaciously to gear teeth even when meshing vertically or under severe dust conditions typical in heavy‑duty mill operations. It is engineered to maintain lubrication integrity and protect exposed gear surfaces from wear, abrasion and shock loads in demanding industrial settings.
Key Features & Benefits
-
Heavy‑duty open gear lubrication: Formulated for mill drives and slow‑speed, highly loaded gear applications typical of mining, cement and processing equipment.
-
Excellent load carrying & anti‑wear performance: Proprietary Molub‑Alloy solid lubricants help reduce metal‑to‑metal wear under high pressure and shock load conditions.
-
Strong film retention & adhesion: Designed to resist squeeze‑out and packing in gear tooth roots, including vertical gear meshing.
-
Wide operating temperature range: Usable approximately from –30 °C up to +100 °C, adaptable based on application conditions.
-
Synthetic/mineral oil blend: Ensures better pumpability at lower temperatures and sufficient film thickness at low speeds and high loads.
-
Free from harmful constituents: Formulated without lead, antimony, barium, bitumen or chlorinated solvents to address environmental concerns.
