Lubricating Oil Japan Original THK AFJ GREASE Machine Tool Guide Screw Maintenance Grease 16KG / barrel
AFJ grease adopts refined mineral oil as the base oil, and with the use of urea-based thickeners and special additives, is a wide range of speeds from low to high speeds have excellent lubricity of the grease.
Characteristics:
(1) Wide speed range
Stable lubricity can be realized in a wide range of speeds from low to high.
(2) Abrasion resistance
Excellent film formation even at low speeds reduces wear.
(3) Vibration resistance
Reduces wear caused by mechanical vibration at high speeds.

In order to fully utilize the function of the linear motion system, please lubricate it according to the conditions of use. If the system is used without lubrication, the rolling parts may wear out faster, resulting in a shorter service life.
Lubricants have the following effects.
(1) Reduces friction between moving parts, thus preventing burns and reducing wear.
(2) Forms a film of oil on the rolling surface to reduce the stress on the surface and extends rolling fatigue life.
(3) Covers metal surfaces with a film of oil to prevent rusting.
In addition, even if the linear motion system is equipped with a sealing gasket, its internal lubricant will gradually leak outward during movement, so the grease must be replenished at appropriate intervals according to the conditions of use.
Linear motion systems mainly use grease or sliding surface oil as their lubricant. The requirements to be met by the lubricant generally include the following.
(1) Higher resistance to extreme pressure
(2) can reduce friction
(3) Improved wear resistance
(4) Excellent thermal stability
(5) Excellent rust protection
(6) Excellent fluidity
(7) The consistency of the grease does not change significantly even after repeated mixing.
