Bearings for Emergency Rotary Beacon Lights

Bearings for Emergency Rotary Beacon Lights

bearing in rotary beacon lightPlastic radial or 4 point contact ball bearing assemblies are used in Rotary Beacon light applications. They are designed to be maintenance free and operate without lubrication allowing them to be non-contaminating to electronics while surviving the application challenges of humidity, rain, snow, and hot or cold climates. Plastic race bearings improved the performance and capabilities over the conventional steel bearings while providing a substantial cost savings.

Critical Design features: Acetal POM plastic races fitted with 316 stainless balls. Features a single or double row or 4 point contact True Race Technology™ ball groove construction for optimum load, stiffness, and moment loading capability.

  • Low friction: A plastic race bearing will naturally have a lower coefficient of friction than a metal to metal ball bearing. A reduction in cost can then be achieved by utilizing a smaller motor.
  • Weight Savings: A KMS plastic ball bearing is 1/5 the weight of a steel bearing thereby reducing the weight of your overall unit.
  • Value added capability: A KMS plastic bearing can be designed to include mounting features, gears, or pulleys, and can also be integrated to the application at no added cost to the bearing. This capability can reduce assembly time while improving the performance of your product.

Plastic Vs Steel

Cleanliness/Hygienic: Plastic bearings generally operate cleaner than metal bearings because they do not need lubrication, they are resistant to corrosion, and they can be washed down without the worry of re-lubing. This capability makes them a viable option for clean room environments, and wash down applications. A plastic bearing made from either PBT, PVDF or PEEK can be post sterilized by standard methods such as autoclave or Gamma.
