NSK’s Sensor Bearings for industrial machinery are sealed for life, maintenance free, high performance ball bearings with superior resistance to magnetic flux. NSK sensor bearings have a magnetic encoder to detect rotating speed and direction. Compared to conventional externally mounted sensors NSK offers compact sensor bearings that enhance opportunities to downscale associated equipment, and simplify the assembly process.
