THK-AFA Grease THK ORIGINAL GREASE
AFA Grease is a high-grade grease that possesses a long service life, excellent water resistance, and low sliding resistance through the use of high-grade synthetic oil as the base oil and a ureabased consistency enhancer.
[Features]
1. Low sliding resistance
As the kinematic viscosity of the base oil is low, it is ideal for long-stroke, high-speed LM Guide operations.
2. Water resistance
It is less vulnerable to moisture penetration than other types of grease because of its high water resistance.
