Mobiltemp SHC Series Product Data Sheet

Mobiltemp SHC SeriesSuper Premium Synthetic High Temperature Greases

Product Description

Mobiltemp SHC Series are super premium quality antiwear greases primarily intended for high temperature applications. They combine the unique features of synthetic base fluids with those of an organo-clay, non-soap thickener. The wax-free nature of the synthetic base fluid and its low traction coefficient (compared with mineral oils), provide excellent stability against oxidation at high temperatures as well as superior low temperature lubrication. They offer the potential for energy savings through reduced friction and lower torque, and reduced temperatures in the load zone of rolling element bearings. The clay thickener contributes excellent structural stability at very high temperatures and a high grease dropping point.

Mobiltemp SHC Series contain no lead, chlorine or nitrites.

Benefits

Mobiltemp SHC Series offer the following benefits:

m Reduced downtime and lower maintenance costs due to outstanding high and low temperature performance

m Extended service life with longer intervals between relubrication because of excellent resistance to oxidation

m Reduced energy consumption (low coefficient of traction)m Maintenance of grease structure at high temperaturesm Outstanding low temperature pumpabilitym Reduced volatility

Applications

Mobiltemp SHC 22 is recommended for ultra high speed rolling element bearings, particularly

machine tool spindle bearings, operating in the speed range up to one million DmN. Generally such high speed bearings require a firm grease with a low viscosity base fluid, having good antiwear properties for long bearing life. Mobiltemp SHC 22 is formulated with an ISO VG 22 base fluid and is a NLGI 3 Grade grease.

It is important that the initial grease pack is about one-third full to allow the grease to be pushed away from the ball/roller track during normal operation. If the bearing is too full, high temperatures may develop because of excessive churning of the grease.

Mobiltemp SHC 22 has a recommended operating temperature range of -50oC to 180oC (with appropriate relubrication intervals), making it particularly suitable for extreme temperature applications.

Mobiltemp SHC 100 is recommended for use in high speed bearings and thrust bearings where a wide temperature range is desired, and also in high temperature applications where extended service between relubrication intervals is required. It is particularly suitable for use in electric motor bearings where operating conditions demand reduced friction, low wear and long service life.

Mobiltemp SHC 100 has a recommended operating temperature range of -50oC to 200oC, with appropriate relubrication intervals.
