Product Description
MOLYKOTE® Longterm 2 Plus Extreme Pressure Bearing Grease is a black, mineral-oil-based, lithium-soap grease for highly loaded metal-to-metal components operating at slow to medium-fast speeds. The NLGI Grade 2 formulation contains solid lubricants and extreme-pressure additives that provide wear protection under mixed-friction conditions. It is designed for long-term lubrication of bearings, spline profiles, clutches, guides, slides, and power screw drives, including equipment exposed to moisture, fretting corrosion, or groove formation. The grease can be applied manually or through compatible central lubrication systems and has a normal service-temperature range of −25°C to 110°C.
Key features
- High load-carrying capacity: Provides a typical four-ball weld load of 3,800 N.
- Mixed-friction wear protection: Uses solid lubricants and extreme-pressure additives to protect loaded metal contacts.
- Long-term lubrication: Formulated for extended lubrication of suitable components and operating conditions.
- Good adhesion: Contains an adhesion improver to help retain the grease on lubricated surfaces.
- Corrosion and fretting protection: Suitable for components exposed to moisture or oscillating contact.
- Central-system application: Can be applied by brush, spatula, automatic lubrication device, or compatible central lubrication system.
Applications / Suitable for
- Rolling-element and plain bearings
- Spline profiles and clutches
- Slides, guides, tracks, bushings, and sleeves
- Power screw drives
- Motor vehicles, tractors, cranes, earth-moving machinery, conveyors, and forklift trucks
- Components exposed to moisture, fretting corrosion, or groove formation
