Bearings and the Restriction of Hazardous Substances Directive

February 19, 2016 by Christine Berlly

rohsThe Restriction of Hazardous Substances (RoHS) directive restricts the use of hazardous materials found in electrical and electronic products sold in the European Union, and bearings must be selected with these regulations in mind.

Any business that sells applicable products, sub-assemblies or components directly to RoHS countries (or sells to resellers, distributors or integrators that in turn sell products to these countries) is impacted if they utilize any of the restricted materials.

Often referred to as the ‘lead-free directive’, the RoHS does, in fact, restrict lead levels, but also a number of other materials as well:

  • Lead (Pb): < 1000 ppm
  • Mercury (Hg): < 100 ppm
  • Cadmium (Cd): < 100 ppm
  • Hexavalent Chromium: (Cr VI) < 1000 ppm
  • Polybrominated Biphenyls (PBB): < 1000 ppm
  • Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
  • Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
  • Benzyl butyl phthalate (BBP): < 1000 ppm
  • Dibutyl phthalate (DBP): < 1000 ppm
  • Diisobutyl phthalate (DIBP): < 1000 ppm

The following product categories are impacted under the RoHS Directive:

  • Large household appliances: refrigerators, washers, stoves, air conditioners
  • Small household appliances: vacuum cleaners, hair dryers, coffee makers, irons
  • Computing & communications equipment: computers, printers, copiers, phones
  • Consumer electronics: TVs, DVD players, stereos, video cameras
  • Lighting: lamps, lighting fixtures, light bulbs
  • Power tools: drills, saws, nail guns, sprayers, lathes, trimmers, blowers
  • Toys and sports equipment: video games, electric trains, treadmills
  • Automatic dispensers: vending machines, ATM machines

And the following markets are exempt from RoHS compliance:

  • Medical devices and equipment
  • Control and monitoring equipment
  • National security use and military equipment
  • Large stationary industrial tools
  • Certain light bulbs and some batteries
  • Spare parts for electronic equipment in the market before July 1, 2006
