Kyodo Yushi GC Grease 350
Product Made in Japan
Manufacturer : Kyodo Yushi
Model: GC Grease 350
High performance grease for couplings which was developed focusing on resistances to wear and leakage especially. Using heat resistance urea thickener, special adhesive, EP agent and solid lubricant, GC Grease 350 excels in resistance to oil separation and adhesion. It offers superior lubrication effect under high surface pressure sliding lubrication conditions.
Characteristics of GC Grease 350
- 1.Extreme pressure property
- In high-load operation, it shows excellent resistance to seizure or wear.
- 2.Flow properties
- Recommended for sliding lubrication under a high surface pressure conditions for its excellent inflow performance onto lubrication surface.
- 3.Leakage resistance
- The separation between the thickener and the base oil is small in amount which prevents leakage from couplings.
- 4.Adhesive properties
- Containing highly adhesive thickener and special adhesive, the grease controls metal contact and spattering caused by centrifugal force.
Main applications and applicable components
- Joints such as gear couplings and spindle shafts of universal joints
Applying a general purpose grease frequently results in softening and leakage due to shearing or centrifugal force caused by rotation, and it could trigger off gear troubles including wear/seizure.
Use of GC Grease 350 reduces the grease amount in use, enabling the life of the machine to extend in addition to preventing environment from pollution caused by grease spattered.
Moreover, it could be applied to lubrication points which require grease to equip inflow performance, adhesion and extreme pressure property.

Adhesive properties
- GC Grease 350 boasts the rate of grease loss which is nearly 1/3 of that of high-viscosity gear oils on the market.
ASTM D 2596: Test on grease loss caused by centrifugal force
- Apply 25g of a grease evenly on a 200m diameter steel plate.
- Rotate a plate vertically placed on the test machine at a speed of 500 rpm for 10 min. Then, calculate grease loss rate.
Load carrying capacity
- GC Grease 350 has load carrying capacity higher than those of general purpose EP lithium greases.
High-Speed Four-Ball EP
