THK L100 Grease – Cleanroom Lubricating Grease for High Loads
THK L100 Grease for Cleanroom and High-Load Applications
THK L100 Grease is developed for applications requiring both low dust generation and reliable lubrication under high loads. Its formulation makes it a specialized Cleanroom Lubricating Grease for suitable linear motion systems and precision equipment operating in controlled environments.
Unlike conventional general-purpose lubricants, THK L100 Grease combines low-dust characteristics with enhanced extreme-pressure resistance, helping support stable lubrication under demanding mechanical conditions.
Key Features of THK L100 Grease
Low dust generation: Designed to reduce lubricant-related particle generation in suitable cleanroom applications.
High extreme-pressure performance: Offers approximately three times the extreme-pressure resistance of THK's previous low-dust-generating greases, according to the manufacturer's comparison.
Synthetic base oil: Uses high-grade synthetic oil with a lithium complex thickener.
Reliable load-bearing lubrication: Suitable for specified high-load linear motion applications.
Wide service temperature range: Manufacturer-listed operating temperature range of -40°C to +150°C.
As an EP High-Performance Grease, THK L100 Grease is intended for applications where load-carrying capability and low dust generation are both important selection factors.

Typical Applications
Depending on equipment requirements and manufacturer recommendations, THK L100 Grease may be considered for:
Linear motion guides and rolling-element systems.
Precision machinery operating in suitable clean environments.
Equipment requiring low-dust lubrication and high load-carrying performance.
Industrial motion systems where extreme-pressure resistance is an important requirement.
Before selecting this Cleanroom Lubricating Grease, verify the machine model, lubrication point, operating conditions, and applicable regional restrictions.
How to Choose the Right THK L100 Grease
When sourcing THK L100 Grease, confirm the exact product designation, packaging size, and compatibility with your equipment. Review the manufacturer's technical documentation before replacing an existing lubricant or mixing different grease formulations.
Important regional note: THK states that L100 Grease cannot be used in Europe. Buyers should confirm applicable restrictions and intended-market suitability before ordering.
