The sensors record speed and sense of rotation. From these data the angular acceleration and number of revolutions can be derived. This information is increasingly needed in control engineering in order to monitor plants electronically and run them automatically. Typical applications for rolling bearings with an integrated sensor include electric machines especially frequency-controlled three-phase asynchronous motors transmissions e.g. in machine tools transmission motors materials handling equipment e.g. elevators escalators belt conveyors fork lift truck drives textile and packing machinery Advantages of FAG sensor bearings FAG deep groove ball bearings with an integrated sensor offer several advantages over solutions involving separate incremental encoders and other solutions Low cost Sensor bearings cost up to 50 less than solutions with incremental encoders Little space required Bores and O.D.s are the same as those of standard deep groove ball bearings only the overall width is greater by 8 mm space-saving cable outlet in circumferential direction and strain relief Simple mounting Sensor bearings are ready-to-mount units no adjustment required integrated anti-rotation system Maintenance-free bearings Standard deep groove ball bearings with a shield or seal on one side gap-type seal on the other side for-life lubrication Can be used as locating bearings Sturdy sensor housing allows axial loads High measuring accuracy High pulse frequency and low dividing error Good electromagnetic compatibility .
