Roll Guide Bearings for Medical and Dental Lighting

roll guide bearingsKMS has developed a plastic ball bearing for a medical  and dental track lighting system. It is designed to be maintenance free and operate without lubrication allowing it to be non-contaminating to the surrounding environment. Plastic race bearings improve the performance and capabilities over conventional steel bearings while providing a substantial cost savings through integration.

Critical Design Features: Acetal POM plastic races fitted with 316 stainless balls. Double row, True Race Technology™ ball groove construction allows for optimum load, stiffness and moment loading capability. Outer ring profile is machined to ensure a high quality, smooth running performance. 

Additional reasons for use:

  • No lube required: the ability to run without lubrication is a benefit when cleanliness is a priority.
  • Low friction: A plastic race ball bearing will naturally have a lower coefficient of friction than a metal to metal ball bearing.
  • 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. This capability can reduce assembly time while improving the performance of your product.

Plastic Vs Steel

Shock Absorption: Plastic absorbs shock loads better than metal due to its elastic nature. Many conventional ball bearings fail due to Brinelling of the raceway, i.e. balls denting the raceways.
