Multi Track Magnetic Encoder Integrated Rolling Bearing
This is a unit product integrating bearing with magnetic type encoder. By reading changes in magnetic poles of “Multi Track Magnetic Ring” attached to inner ring of bearing with magnetic sensor IC equipped with outer ring, it can detect rotational speed, direction, and absolute angle.
The product eliminates the need for transmission devices like couplings that connect joint shaft and rotary encoder, achieving downsizing/lightweighting of robot joint. The operation for mounting/setting up couplings is also eliminated, making assembly of robot easier. Dimensions and load capacity of the bearing in the product are the same as those of conventional bearings, and can be applied to a wide range of robots.
