Original Grease AFF Grease
AFF grease uses high-grade synthetic oil as its base and a lithium-based grease as its consistency enhancer, while also featuring special additives. This gives it excellent anti-fretting and low dustgenerating performance. It also features a level of stable rolling resistance not found in other conventional vacuum and low dust-generating greases.
Features
Features
- Stable rolling resistance
Since the viscous resistance is low, the rolling resistance fluctuation is also low. Thus, superb conformity is achieved at low speeds. - Low dust generation
It generates very little dust, making it ideal for use under micro-stroke conditions. - Fretting resistance
Since AFF grease is more resistant to wear from micro-vibrations than other low dust-generating greases, it allows the greasing interval to be extended.
