As far as I can see from the contents of your consultation,
・Vacuum environment (absolute pressure: approx. 1.0 kPa)
・Temperature of the guide section: approx. 100°C
・Operating environment with ceramic powder dispersal
We understand that the trouble is caused by extremely harsh conditions for lubricants, such as the following.
We are sorry to hear that the urea grease and molybdenum dry film lubricant used in the past showed lubrication deterioration due to the effects of powder and heat.
■Recommended Products and Usage
Under the above conditions, we suggest the following combination method among our high-performance lubricants.
〇Bell Hammer GOLD Spray + Metal Grease
Apply Bellhammer GOLD Spray lightly
⇒ Forms a lubricating film on the metal surface, and is effective for initial blending and wear suppression at the time of dry start.
It forms a lubricating film on the metal surface to prevent initial blending and wear during a dry start.
Apply an appropriate amount of metal grease on top of the spray.
⇒ Excellent extreme pressure and heat resistance ensures long-lasting lubrication performance.
This two-step application process can be expected to have the following effects compared to the use of conventional grease alone
The following effects can be expected compared to the use of conventional grease alone:
Long-lasting lubrication performance
Prevention of scattering and deterioration in powdery environments
Prevention of wear of sliding metal parts and improvement of operational stability
In fact, this product has a proven track record of use under high temperature, high load, and dusty environments, and has been highly evaluated under extreme conditions in circuit vehicles, heavy maintenance equipment, tuning vehicles, and other applications.

■Precautions for use
The structure of the product is said to be prone to accumulation of ceramic powder, so we recommend periodic cleaning of the product.
Our products are designed to have low volatile outgassing (volatile components) in a vacuum environment, and are used safely in many industrial equipment.
