MOLYKOTE 3451 Chemical Resistant Bearing Grease: A Reliable Lubrication Solution for Harsh Chemical Environments

Why Choose MOLYKOTE® 3451 Bearing Grease?

Industrial equipment operating around chemicals, fuels, cleaning agents, or solvents often experiences premature lubricant degradation. Conventional lithium or synthetic greases may lose their lubricating properties when exposed to aggressive media, leading to increased wear and unexpected downtime.

MOLYKOTE® 3451 Chemical Resistant Bearing Grease is engineered to overcome these challenges. Formulated with a fluorosilicone base oil and PTFE thickener, it provides stable lubrication across a broad operating temperature range while maintaining excellent resistance to water, fuels, acids, and many industrial chemicals.

Key Features

• Outstanding resistance to chemicals, fuels, and industrial solvents
• Excellent oxidation and water washout resistance
• Wide operating temperature range from -40°C to +232°C
• High load-carrying capability for demanding bearing applications
• Compatible with many engineering plastics, elastomers, and sealing materials
• Long service life, helping reduce relubrication intervals
• Suitable for high-speed sealed bearings requiring long-term lubrication
