Bearings monitor status of motion system

SKF offers Sensor-Bearing Units as a compact, patented, and reportedly cost-effective way to verify motion status of rotary or axial components running in open-loop or closed-loop motion control systems. SKF Sensor-Bearing Units integrate one of the company's Explorer-class, single-row, deep-groove ball-bearings with an SKF active sensor in a simple, lightweight but robust structure.

SKF offers Sensor-Bearing Units as a compact, patented, and reportedly cost-effective way to verify motion status of rotary or axial components running in open-loop or closed-loop motion control systems. SKF Sensor-Bearing Units integrate one of the company's Explorer-class, single-row, deep-groove ball-bearings with an SKF active sensor in a simple, lightweight but robust structure. The bearing performs all dynamic functions associated with ball bearings. The active sensor consists of three parts: a magnetized impulse ring attached to the bearing's inner ring or race; sensor body with Hall-effect sensors carried by the outer ring; and connecting cable. Shielding is provided against external electromagnetic effects.

Operating principle of the bearing unit is the generation of a magnetic field of changing polarity as the impulse ring—and bearing inner race—rotates past the outer stationary sensor ring. Based on the number of polarity changes per second, an output pulse is produced by the sensor, which is transmitted via the connecting cable to generate the required application-specific information.

  • Sensor/bearing combination can serve instead of incremental encoders

  • Shielding guards against external electromagnetic effects

  • Speeds down to zero can be recorded

  • High signal quality, vibration, temperature tolerance makes it good for electric motors, linear actuators, steering systems, conveying and handling systems, and other automation
