THK AFJ Grease – Wide-Speed-Range Lubricating Grease
THK AFJ Grease for Precision Motion Systems
THK AFJ Grease is designed for applications where operating speeds vary from low to high. Its formulation supports consistent lubrication, helping protect moving components in linear motion guides, ball screws, and other compatible mechanical systems.
For industrial equipment requiring dependable motion performance, THK AFJ Grease combines wear resistance with lubrication characteristics suited to changing operating speeds. It is particularly relevant to machinery exposed to repeated movement and vibration.
Key Features and Benefits
Wide-speed-range lubrication: Supports consistent lubrication under both low-speed and high-speed operating conditions.
Wear resistance: Helps reduce wear through effective oil film formation, including during low-speed operation.
Vibration resistance: Helps reduce wear associated with machine vibration during high-speed operation.
Low rolling resistance: THK test data demonstrate reduced rolling resistance in specified LM guide and ball screw test conditions.
Urea-based formulation: Uses refined mineral oil as the base oil and a urea-based thickener, together with special additives.
These properties make THK AFJ Grease a specialized option for suitable precision motion applications where operating speed, vibration, and component wear are important considerations.

Applications
THK AFJ Grease may be considered for compatible applications such as:
Linear motion guides and rolling-element systems.
Ball screws and precision positioning mechanisms.
Industrial automation equipment with varying movement speeds.
Machine tools requiring reliable lubrication under repeated motion.
Mechanical systems exposed to vibration during operation.
ForCNC Machine Tool Lubrication, selecting the correct grease helps support smooth component movement and equipment reliability. However, the lubricant must match the specific guide, ball screw, or bearing requirements stated by the equipment manufacturer.
Why Choose THK AFJ Grease?
When selecting a Wide-speed-range grease, buyers should consider more than the nominal operating speed. Load, vibration, lubrication method, temperature, and component design all affect lubricant suitability.
THK AFJ Grease is designed to provide lubrication across a broad speed range while helping control wear. Its application-specific formulation makes it worth considering for compatible linear motion and precision machinery systems.
Before replacing an existing lubricant, check the original grease specification and verify compatibility. Do not assume that different THK grease models are interchangeable.
