For heavy duty bearings
January 1st 2006

Shell Lubricants has developed a polyurea grease that is said to offer excellent performance in heavy industry bearings and to provide operators with reduced maintenance levels, blockage-free centralised lubrication system operation, improved bearing life and increased uptime.

The polyurea formulation of Shell Stamina 0511 has a high resistance to extreme temperatures, enabling those in heavy industry to improve bearing cleanliness and reduce costs associated with grease deposits.

The product will not separate or harden in high temperatures, reducing the risk of bearing damage caused by grease losing its lubrication properties during oxidation, and equipment failure resulting from grease deposits clogging the bearings.

A steel manufacturer has reported estimated cost savings of 300 000 US dollars since switching from a calcium complex grease to Shell Stamina 0511. The grease has enabled the operator to reduce grease consumption by 11mt/month and eliminated system blockages and deposits in the continuous casting equipment bearings.
