Automotive—Squeak and Rattle

Miller-Stephenson has worked extensively with automakers and suppliers to reduce noise, vibration, and harshness (NVH) levels in many vehicles, ranging from luxury cars to light trucks. As a result, Krytox high-performance oils and greases are used by numerous automakers in many automotive applications to reduce squeaks, rattle, and “itch”—a squeak that can develop when rubber or plastic mates against glass or paint. Some of these commercial applications are metal-on-plastic squeak, leather on leather itch, window lace, convertible top seals, front and sliding door seals, steering column gaskets, and weather stripping. Krytox is an excellent lubricant, even in barely detectable quantities. It is easy to apply, either by spraying or brushing. Because it has low vapor pressure and surface energy, and is insoluble in all common solvents, Krytox lubricant stays where you put it. It has also been used in conveyors and other critical equipment in manufacturing facilities.

Automotive—Mechanical Systems

Design/OEM As operating conditions become increasingly hotter, components run faster, standard lubricants begin to fail prematurely, and warranty costs rise, Krytox lubricants can be counted on to handle the challenge. Krytox oils and greases are more than lubricants—they are design components. Krytox lubricants have a superior aesthetic quality and appeal. When a lubricant increases the quality of an automotive component, it becomes as much an essential design element as a gear or a motor. For over 50 years, Krytox lubricants have provided state of-the-art performance for mechanical systems. Krytox technology can provide optimum equipment performance and low life cycle cost through:

  • Prevention of wear and noise from vibration: Krytox lubricants and coatings can minimize the shock and stress in moving parts that create heat, wear, and noise. They stand up to high temperatures and harsh environments, and reduce the chances of component failure.
  • Longer lasting lubrication: For many applications, the typical service life will exceed 10 years or 100,000 miles.

The public demands automobiles that are efficient and reliable. Automakers are striving towards extended warranties, expecting cars and trucks that will not require service visits before 100,000 miles or re-lubrication of sealed bearings and U-joints before 150,000 miles. As consumer and automaker expectations rise, Krytox high performance synthetic lubricants can provide:

  • A wide temperature range
  • Effectiveness: Krytox lubricants keep performing in the toughest conditions: rain, snow, ice, dust, and grit. • Resistance: Krytox lubricants can withstand the fuel, coolant, brake fluid, and washer solvent of the harsh under hood environment. They are resistant to evaporation or changes in characteristics over the many years of an automobile’s serviceable life.
  • Compatibility: Krytox lubricants have no effect on paint and no compatibility issues with other automotive materials or surfaces they may contact. Formula One™3 and NASCAR teams use Krytox lubricants for suspension and steering components, drive train components, and engine auxiliary parts. Use Krytox lubricants to help extend the service life of a variety of car and truck parts:
  • Under hood: fan clutch bearings, emission air pumps, spark plug boots, clutch release bearings, anti lock brake systems, windshield wiper motors, belt pulleys, oil pressure sensors, alternator bearings, and sintered bearings in motors
  • Chassis: wheel bearings, CV/universal joints

• Interior: weather stripping, sunroof seals, window lift mechanism, leather seats, consoles and trim, flocked and unflocked window seals and channels, door handles, switches, air vents, controls, and airbag covers

Krytox lubricants even help improve performance in the auto manufacturing environment, providing lubrication for paint oven conveyor trolleys.

Power Generation

Krytox lubricants provide optimum performance for mechanical systems, such as turbine auxiliary systems, gearboxes, dampers, valves, gaskets, high voltage and circuit breakers, seals, and other components.

Krytox lubricant technology can provide the best available equipment performance and lowest available life cycle cost through:

  • Longer lasting lubrication: reduction of the amount of lubricant needed by 10 times or greater, therefore decreasing costs and frequency of re-lubrication. Krytox can extend lubrication intervals from weekly to annually or even longer in some equipment.
  • Reduced wear and tear on component parts, reducing the chances of component failure.
  • Improving steam turbine performance of the cam shaft bearing and fulcrum pins, despite constant exposure to extremely high temperatures. Krytox XHT-BDZ improves the reliability for steam turbine governor control valves.

Pulp and Paper

Choose the lubricant that can move pulp and paper productivity to new levels.

In the extreme conditions of pulp mill and paper machine equipment, the selection of lubricants can affect production equipment up time and life cycle costs. Krytox lubricants provide endurance through heat, stay in place in the presence of steam or water, and do not react with the chemicals used in production processes. Consider these critical factors:

  • Frequency of lubrication: With some lubricants, pulp and paper mill equipment requires frequent re-lubrication, which can impact production and be costly over time.
  • Extreme production environments: High temperatures and harsh chemicals can cause lubricant breakdown, compromising performance and leading to additional maintenance effort.
  • Safety and environmental concerns: Some lubricants contain volatile organic chemical or chlorinated materials, which can be hazardous to the environment and plant employees. Frequent re-lubrication increases employee exposure to dangerous, high-temperature areas.

As in power generation and other industries, Krytox lubricants provide optimum performance for mechanical systems, such as turbine auxiliary systems, gearboxes, dampers, valves, gaskets, seals, and other components.

Krytox technology can help provide the best available equipment performance and lowest available life cycle cost through:

  • Longer lasting lubrication: Reduction of the amount of lubricant needed by 10 times or greater, therefore, decreasing costs and frequency of re-lubrication. Krytox can extend lubrication intervals from weekly to annually—and much longer in some equipment, such as soot blower carriages.
  • Reduced wear and tear: Krytox lubricants can decrease wear on bearings, gears, and stand up to the extreme temperatures of 107–399 °C (225–750 °F) and harsh chemicals that can significantly reduce maintenance efforts and the chance of component failure.
