G. Beslux Plex Bar L-2 (along with its synthetic variant, G. Beslux Plex Bar L-2/S) is a premium, high-performance barium complex grease manufactured by Brugarolas, Spain. It is specifically engineered to lubricate high-speed precision bearings operating under harsh environmental conditions.
Key Specifications and Technical Characteristics
- Thickener Type: Barium complex soap, which provides outstanding mechanical stability and chemical resistance.
- NLGI Consistency: Grade 2 (medium stiffness, ideal for rolling element bearings).
- Speed Factor(N x Dm): up to 1 x 10^6, making it excellent for ultra-high-speed operations.
- Operating Temperature Range: -50C to +150C for the synthetic base variation.
- Drop Point: Minimum 220C
- Color: Cream / Ivory.
Key Benefits and Features
- Aggressive Environment Resistance: It offers superb resistance against water wash-out, hot water vapor, and both acidic and alkaline solutions.
- Structural Stability: Excellent adhesion to metal surfaces prevents the grease from being thrown off by high centrifugal forces or heavy vibrations.
- Extended Service Life: Exceptional aging and oxidation resistance drastically prolong relubrication intervals, lowering overall consumption.
- Wear Protection: It features high anti-wear and Extreme Pressure (EP) characteristics to protect precision surfaces under dynamic loads.
Primary Applications
- High-Speed Machine Tool Spindles: Protects internal elements of high-speed CNC and machining spindles.
- Electric Motor Bearings: Ideal for high-rpm industrial motors operating in humid or chemically aggressive environments.
- Textile and Precision Machinery: Used heavily in precision industries where low start-up torque and reliable high-speed operation are critical.
- Wet Ambiences: Perfect for components frequently exposed to cooling fluids, moisture, or chemical vapors.
Important Handling Cautions
- Avoid Mixing: Do not mix this grease with lubricants that use a different thickener type (e.g., lithium or polyurea), as it will degrade performance.
- Contamination Control: Keep grease containers tightly sealed to prevent environmental dust or moisture from contaminating the product.
