Angle Encoders without Integral Bearing

The HEIDENHAIN ERP, ERA and ERO angle encoders without integral bearing are intended for integration in machine elements or components. They operate without friction and permit high accuracy. This makes them particularly attractive for high-precision angle measuring tables and precision devices in angular metrology. The attainable system accuracy depends on the eccentricity of the graduation to the drive shaft bearing, as well as the radial runout and wobble of the bearing.
