Flex Coupling Grease for High-Speed Industrial Applications

High-Performance Synthetic Flexible Coupling Grease and High RPM Equipment

Petro-Canada Peerless XCG FLEX Coupling Grease is a specialized flex coupling grease formulated to meet the extreme demands of high-speed coupling systems. Designed for excellent mechanical stability and superior adhesion, this premium product protects rotating equipment in industrial settings where centrifugal forces, temperature fluctuations, and misalignment are common.

This synthetic-based grease resists sling-off at high RPMs and stays precisely where it’s needed, even in heavily loaded or vibrating coupling applications. As a result, it helps reduce wear, vibration, and noise—while also extending the service life of your coupling components.

Right from the start, this flex coupling grease delivers performance where other greases fall short. It maintains its consistency under shear and resists separation even in couplings operating at up to 3,600 RPM. Whether used in gear, grid, or chain couplings, Peerless XCG FLEX forms a resilient lubricating film that keeps metal surfaces protected against scoring and pitting.

Its superior resistance to oxidation and thermal degradation ensures long-lasting lubrication, even in high-temperature environments. At the same time, it protects against corrosion and resists water washout—making it a dependable option for both indoor and outdoor operations.

Additionally, this grease is designed to reduce coupling wear, minimize maintenance intervals, and support smoother operation across power transmission systems. It also performs exceptionally well in electric motors and other rotating equipment that relies on reliable, non-throwable lubrication.
