Castrol Alpha BMB 680, 20L

Castrol Alpha BMB 680 is a high-performance CLPF-class industrial gear oil containing finely dispersed molybdenum disulfide (MoS₂) solid lubricant. Its thermally and chemically stable MoS₂ suspension offers outstanding protection against shock loads and minimizes wear under severe operating conditions.

Application:

Designed for lubrication of slow-moving, heavily loaded industrial gear units and machinery exposed to shock loads and vibration – such as rotary kiln drives, ball mills and rolling mills. Provides excellent boundary lubrication even in case of temporary oil starvation, preventing damage due to metal-to-metal contact. Operates efficiently across a wide range of temperatures.

Features and benefits:

• High shock load resistance: protects gears and bearings under abrupt load changes.
• MoS₂ solid lubricant: ensures continued lubrication during start-up and mixed friction conditions.
• Thermal and oxidative stability: maintains performance during extended high-temperature operation.
• Excellent anti-corrosion properties: guards against rust formation even in humid environments.
• Compatible with seals and non-ferrous metals.

Specifications and standards:

• DIN 51517-3 (CLP)
• DIN 51502 (CLPF)
• FZG A/8.3/90 and A/16.6/140: >12 load stage
