Castrol Contractor’s Special is a lithium complex grease with extreme pressure additives containing 3% Molybdenum Disulfide. Castrol Contractor Special is formulated to offer high temperature and heavy-duty performance coupled with good pumpability for applications where a tough durable lubricating film is needed. Castrol Contractor ‘s Special delivers better productivity and less downtime where “boundary lubrication” exists while extending lubricant usage, longer equipment life, and reduced lubrication frequency.
Advantages
•Castrol Contractor’s Special delivers:
•Superior film strength and anti-wear package with a high load capability
•Excellent pumpability for automatic systems
•3% Molybdenum Disulfide to reduce friction.
•High dropping point
Castrol Contractor Special is suitable for heavily loaded equipment such as bulldozers, shovels, loaders & off-highway trucks. Applications include plain and anti-friction bearings, ball joints, king pins, hinge, and bucket pins, and heavy duty chassis lubrication.
