OKS 1140

OKS 1140 Extreme-Temperature Silicone Grease

Description

OKS 1140 is an exceptional extreme-temperature silicone grease designed specifically for slow-running machine elements operating under extremely high temperatures. Whether you’re dealing with kiln trolleys, bakery machines, drying tunnels, foundry equipment, or plastics processing machines, OKS 1140 ensures reliable lubrication and reduced wear even in the most demanding environments.

Performance of OKS 1140

• Durable: OKS 1140 thrives in corrosive and high-temperature conditions, providing long-lasting lubrication.
• Optimum Formula: Its temperature-stable silicone grease formula ensures effectiveness across a broad range of temperatures.
• Versatile Use: OKS 1140 is well-suited for grease lubricating points subject to extreme temperature loading.

Features of OKS 1140

1. High-Temperature Stability: OKS 1140 operates effectively at temperatures that challenge conventional greases.
2. Noise Reduction: It minimizes gear noise, enhancing overall system efficiency.
3. Shock Absorption: OKS 1140 protects against impulsive loads and shocks.

Benefits of OKS 1140

• Reduced Leakage: Compared to oil lubrication, OKS 1140 significantly reduces leakage loss.
• Wear Protection: It extends the lifespan of gears, bearings, rollers, and transport chains.
• Corrosion Resistance: OKS 1140 withstands corrosive environments.
• Adhesive Properties: The grease adheres well to surfaces, ensuring consistent lubrication.

Specifications

• Lower Operating Temperature: -20°C (≤ 1,400 hPa)
• Upper Operating Temperature: 290°C
• Consistency: NLGI grade 2 (DIN ISO 2137)
• Viscosity (at 40°C): 100 mm²/s (base oil)
• Four-Ball Test Rig Welding Load: 2,100 N

Applications

For optimal results:

• Clean lubricant points and surfaces carefully using OKS 2610 or OKS 2611 universal cleaner.
• Remove any corrosion protection agents before initial filling.
• Fill bearings to ensure all functional surfaces receive sufficient grease.
• Slow-moving bearings (DN-value < 50,000) should be filled completely, while normal-moving bearings should be filled to 1/3 of the free inner housing space.
• Follow the instructions provided by the bearing or machine manufacturer.
• Relubricate using a grease gun on the grease nipples or via an automatic lubrication system.
• Define relubrication intervals and amounts based on service conditions.
• If old grease cannot be removed, limit the amount to avoid over-lubrication.
• Consider a complete exchange of old grease for longer relubrication intervals.
• Mix only with appropriate lubricants.
• Bearings filled with silicone grease must not exceed 1/3rd of the bearing’s permitted load.
• Avoid applying silicone grease to sliding surfaces under the influence of pure oxygen.

Flash Point and Drop Point

• Flash Point: The flash point of OKS 1140 is approximately 250°C (482°F). This indicates the temperature at which the grease can ignite when exposed to an open flame.
• Drop Point: OKS 1140 does not have a drop point because it is a silicone-based grease.

Viscosity

The viscosity of OKS 1140 at 40°C is 100 mm²/s (base oil). This ensures smooth lubrication even under extreme temperature conditions.

Frequently Asked Questions (FAQs) about OKS 1140

1. Q: Can OKS 1140 be used in food processing equipment?
   • A: No, OKS 1140 is not recommended for food-contact applications. Please choose a food-grade lubricant for such environments.
2. Q: Is OKS 1140 suitable for use in high-temperature kiln trolleys?
   • A: Yes, OKS 1140 is specifically designed for slow-running machine elements operating under extremely high temperatures, making it ideal for kiln trolleys and similar applications.
3. Q: How often should I reapply OKS 1140 in extreme environments?
   • A: Reapply based on operating conditions and manufacturer recommendations. Regular inspections are essential.
