Designed to promote increased reliability and machine uptime by protecting against potential damage caused by the passage of electric currents in ac and dc motors, the INSOCOAT electrically-insulated rolling bearings feature a thin aluminum oxide layer. The layer is meant to form an excellent barrier against electric arcing, which typically causes fluting damage to roller and raceways or grease oxidation. They have performance tested to 1,000V dc with a minimum ohmic resistance of 50M.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
