SKF ball bearings for electric motors have been introduced as alternatives to standard bearings by generating significantly less friction and reducing energy consumption. These deep groove ball bearings join a growing family of SKF energy efficient bearing solutions. The bearings exhibit 30 to 50 percent lower friction compared with conventional types and benefit from an optimized design balance between highly engineered internal geometries, grease and bearing cages. Additionally, these bearings promote smooth-running performance and generate less noise and heat. Extended bearing service life up to double the ISO calculated life can be realized, according to the company's press release. The bearings comply with ISO 15:1998 in a range of select off-the-shelf sizes to allow for interchangeability within existing design envelopes. They can be specified for electric motors up to 37 kW with shaft dimensions up to 60 mm. Custom solutions can be developed to satisfy particular application needs.
