Characteristics of Silicone Grease
Silicone grease products are made with a silicone fluid base oil blended with materials such as fillers, oiliness improvers and antioxidants. They have greater thermo-oxidative stability and moisture resistance than common mineral oil-based greases, and can be used in a wider range of temperatures. Furthermore, silicone greases are chemically inert, so they can be used on almost any equipment.
Lubrication in Low Temperature Applications
G30L G30M G30HThe Shin-Etsu G30 series provide superior lubrication particularly in low temperatures (-60°C to +180°C.)
Available in three consistencies (grease hardness): L is softest, followed by M and H.
Lubrication in High Temperature Applications
G40L G40M G40H G420The G40 series are ideal for lubrication of sealed bearings particularly in high temperature applications (-30°C to +200°C.) Available in three consistencies (grease hardness): L is softest, followed by M and H. G420 provides superior lubrication in the very high temperature range (-30°C to +250°C.) The G40 series of greases meets US military MIL-L15719A specifications.
Solvent-resistant Lubrication
FG720 FG721 FG722The FG720 series is a fluorosilicone grease containing flurosilicone fluid as the base oil and the fine powder of fluoro carbon resin. These greases have the characteristics of both silicone and fluorine compounds, so they offer outstanding resistance to heat, solvents and other chemicals. They provide excellent lubrication in high speed, high load conditions.
Non-mineral Oil Lubrication For Rubbers
G411G411 is a non-mineral oil grease for rubber automotive parts. It has excellent resistance to heat and cold. G411 has no adverse effects on synthetic rubber cups. It provides consistent lubrication and meets JIS K 2228 specification.
Plastic Lubrication
G501
G501 uses a special silicone fluid as the base oil. It is specially formulated for lubrication and noise reduction for blower bearings and plastic parts. With G501, there is a low incidence of stress cracks in polycarbonate (PC), polyacetal (POM), ABS and other plastics. It also provides better lubrication for steel-on-steel applications than conventional silicone greases.
Applications for G501
| Sliding parts in air conditioners, ventilation fans, room heaters, and washing machines for lubrication. | Gears in VTRs, fully automatic mechanism of servomotors for lubrication and noise elimination. |
| Plastic gears in printers, typewriters, and other OA machines for lubrication and noise elimination. | Gears in recreational goods such as toys for lubrication and maintenance |
Lubrication for Sliding Parts
G6500G6500 provides good lubricating performance and there is low incidence of stress cracks in plastic. Applying G6500 to sliding parts such as slide volume controls improves the feel and operation life. G6500 is recommended for use in locations with relatively low revolution speeds.
Adhesive Applications (Torque and Damper)
G330 G331 G332 G333 G334G340 G341 G342
G351 G352 G353
Shin-Etsu Silicone grease in the G330, G340 and G350 series provide high adhesion and exhibit little change in torque values resulting from temperature changes. In a range of equipment, these greases are applied to sliding and rotating parts, where their high adhesive strength provides a superior damping effect. The G330 series are low adhesion greases (torque 5-35), whereas the G350 series are high adhesion (torque 40-50.) The G340 series is especially formulated for consistent torque forces in low temperature range.
G631 G632 G633The G630 series were developed for the bearings of variable resistors. These materials impart very stable torque to bearings in resistors. They are also be used for damping.
Applications for G330, G340, G350 and G360 series
| Eject damper mechanisms in cassette decks | Bearing in rotary volume-control resistors and rotary switches |
| Sliding parts in optical instruments | Sliding parts in volume control resistors |
| Shock absorbers and air cylinders |
