MOLYKOTE G-67 Grease 400 g adhesive mineral grease for gears, linear guides and heavily loaded parts
0
Description
MOLYKOTE G-67 Grease 400G is a highly adhesive mineral grease designed for operation under high loads. The product provides effective protection against fretting corrosion and wear, and thanks to its high adhesiveness it remains well on lubricated surfaces. It is a practical solution for gears, linear guides and other moving parts operating under heavy load.
Advantages and unique features
- Highly adhesive grease for high loads
- Good load-carrying capacity
- High level of wear protection
- Effective protection against fretting corrosion
- Adheres well to surfaces
- Suitable for gears and linear guides
- Low coefficient of friction on POM surfaces
- Can be supplied through central lubrication systems
Properties and applications
- For open and closed gear systems: the product is suitable for lubricating gear systems operating under heavy loads.
- For linear motion guides: it is suitable for linear motion systems requiring a durable lubricating film.
- For chains and springs: it can be used on parts exposed to load and friction in motion.
- For shaft-hub connections: it is suitable for lubricating mechanical connections requiring high grease adhesion.
- Protection against fretting corrosion: the product helps reduce wear and damage caused by micro-movements at contact surfaces.
- Compatibility with selected plastics and elastomers: the manufacturer recommends carrying out compatibility tests before use.
