Product Features
Calgraph 2 is formulated with a powerful blend of anhydrous calcium and solid lubricants. Designed to conquer wear and tear in heavy-duty plain bearings and slides, Calgraph 2 acts as a rejuvenating shield, filling in worn surfaces and distributing loads uniformly to prevent further damage.
Key Benefits:
- Good mechanical stability: Ensures the grease maintains its consistency and structure over time, even under heavy loads and vibrations.
- Good water resistance: Protects against water washout and corrosion, making it ideal for use in wet or humid environments.
- Good local stress load distribution: Distributes pressure evenly across bearing surfaces, reducing wear and tear.
- Wide operating temperature range: Performs effectively in a variety of temperatures, without thinning out at high temperatures or becoming too stiff at low temperatures.
- Good oil separation: Minimizes oil separation from the thickener, ensuring consistent lubrication.
- Good sealing properties: Forms an effective barrier to prevent leaks and contamination.
Applications:
- Plain bearings: Calgraph 2 is specifically designed for use on plain bearings that have seen service but still have a long operational life remaining. The solid lubricants help to fill worn surfaces and distribute loads evenly, preventing further wear and extending bearing life.
Calgraph 2's properties make it suitable for a variety of other applications, including:
- Hydraulic rams and plungers
- Chains and guide ropes of lifts and hoists
- And other heavy-duty sliding mechanisms
