Description
Castrol Alpha BMB 220 is a premium mineral-based industrial gear lubricant designed to meet the DIN 51517-3 specification and qualify as a CLPF type gear oil in accordance with DIN 51502 requirements. Its formulation includes matched solid lubricant additives (MoS₂) that stay suspended in the oil to enhance boundary lubrication and improve performance under high load and shock-load conditions, making it suitable for heavy-duty industrial drives, enclosed gearboxes, and slow-speed high-stress gear systems.
The presence of the solid lubricant not only boosts load capacity but also contributes to good ageing stability, high thermal loading capacity, and strong corrosion protection, while maintaining compatibility with non-ferrous metals and common seal materials.
This 20 L canister size is convenient for workshop refills, maintenance servicing, and machinery with moderate oil reservoir capacities, helping ensure reliable lubrication and extended equipment life with fewer oil change intervals.
Key Features
-
CLPF classification with solid lubricant (MoS₂) for exceptional load and wear protection.
-
ISO VG 220 viscosity — suitable for heavy industrial gear applications.
-
High thermal loading capacity and good ageing stability.
-
Corrosion resistance and neutral behavior with seals and non-ferrous metals.
-
Mineral-oil base with added EP/AW/FSS performance.
Typical Uses
Used in industrial enclosed gearboxes, reducers, and heavy-load drives where enhanced boundary lubrication and shock-load protection are critical — such as material handling systems, mining machinery, processing plant gear units, and other demanding mechanical transmissions.
