By utilizing technology for integration of bearings cultivated with Integrated Rotation Sensor Bearings* 2, which are adopted in transport equipment such as forklifts, NTN optimizes the gap and directions of “Multi Track Magnetic Ring” and magnetic sensor IC to realize compact and lightweight unit. By attaching NTN’s proprietary “Multi Track Magnetic Ring * 1” to inner ring of bearing and reading changes in magnetic poles of “Multi Track Magnetic Ring” with magnetic sensor IC equipped with outer ring, the product can detect rotational speed and absolute angle with industry’s highest level in angle detection resolution (maximum 20bit, resolution of approximately 0.00034°). It can detect rotational speed, direction, and absolute angle. The newly developed “Multi Track Magnetic Encoder Integrated Rolling Bearing” is a bearing unit which integrates a deep groove ball bearing that supports robot joints with magnetic ring and sensor. Multi Track Magnetic Encoder Integrated Rolling Bearing Each robot is required not only to improve motion accuracy, but also to reduce the number of components in joints, size/weight of each component, and man-hours in its assembly process. In recent years, the use of robots has accelerated to realize automation and labor saving at manufacturing sites in various industries, reflecting the declining ratio of working-age population in line with decreasing birthrate and aging population, and the types of works which robots take on are becoming diverse. The bearing unit integrates bearing with magnetic type encoder, and contributes to improvement of performance, downsizing/lightweighting of robots, and saving man-hours in assembly and setup. NTN Corporation (hereafter, NTN) has developed “Multi Track Magnetic Encoder Integrated Rolling Bearing” with excellent environmental resistance and high-resolution angle detection. Contribute to improvement of performance and downsizing/lightweighting of robots with excellent environmental resistance and high-resolution angle detection Product using deep groove ball bearing 6907 Dimensions: Inner diameter φ35mm × outer diameter φ55mm × width 20.5mm
