Description
Castrol Molub-Alloy™ OG 936 SF Heavy Open gear compounds (solvent free) NLGI 0
Castrol Molub-Alloy™ OG 936 SF Heavy (previously called Molub-Alloy 936 SF Heavy) is an open gear lubricant developed specifically for use on heavy duty equipment in mining and industrial service. Molub-Alloy OG 936 SF Heavy is compounded to give maximum protection to gears and slides on large draglines and shovels while minimising potential pollutants to the environment.
Application
This product is used extensively in mining, construction, onshore drilling operations and on offshore installations, facilitating effective lubrication and protection on:
- Rack and pinion jacking mechanisms
- Cantilever skidding systems
- Mooring winch open gearing and slides
- FPSO offloading systems
- Crane slew ring & pinion
- Exposed threads on penstock valves
- Heavy duty top dressing for the ultimate protection of wire ropes
Specifications / Approvals
- SD 4713 (CAT)
Advantages
- Formulated to address environmental concerns – it is free of solvents, lead, antimony and Barium
- Forms a tough durable film with a “cushioning” effect, even under extreme pressures and at very slow speeds
- The film resists erosion from rain or sleet, and resists peeling in dusty environments
- The film resists destruction by contaminating oils and greases migrating from nearby mechanisms
