THK AFC Grease – Anti-Fretting Grease for Precision Sliders

THK AFC Grease for Anti-Fretting Protection

THK AFC Grease is developed for lubrication points exposed to micro-vibrations, small oscillating movements, and fretting corrosion. It combines high-grade synthetic base oil with a urea-based thickener and special additives to help protect contact surfaces and maintain lubrication performance.

As an Anti-Fretting grease, THK AFC is particularly relevant to precision motion components where repeated minor movements can cause surface wear, reddish-brown debris, or corrosion. Its wide operating temperature range also makes it suitable for applications that experience changing ambient or operating temperatures.

Key Features and Benefits

• Fretting resistance: Helps reduce wear and corrosion associated with small repeated movements.

• Wide temperature range: Designed for service from -54°C to +177°C, according to THK representative data.

• Synthetic base oil: Supports stable lubrication across a broad temperature range.

• Oxidation stability: Helps maintain grease performance and may reduce relubrication frequency under suitable operating conditions.

• Micro-vibration protection: Suitable for evaluating in mechanisms exposed to vibration or small oscillations.

Technical Specifications

Typical Applications

THK AFC Grease may be considered for suitable lubrication points in:

• Linear motion guides and precision sliders

• Machinery exposed to micro-vibration

• Precision positioning mechanisms

• Equipment where fretting corrosion is a concern

• Industrial motion systems operating across a wide temperature range

For buyers seeking Specialized grease for sliders, the choice should be based on the slider design, load, movement pattern, temperature, and manufacturer's lubrication requirements. THK AFC Grease is intended for fretting resistance; it should not be assumed to be interchangeable with every standard slider grease.
