Rotary table bearings with integrated angular measuring system

The measuring system bearing is identical in design to the rotary table bearings YRTC and YRTS, except for the additional inclusion of a measurement ring of type AMO on the inner ring of the measuring system bearing, which features a regular grating structure as angular pitch with a pitch period of 1000 ?m. A stainless steel strip is used as the carrier material for the measurement ring, into which the periodic angular pitch is introduced by means of a high-precision photolithographic method with subsequent etching process. The measuring system bearings are alternatively available with absolute coded measurement rings, Figure 1, or with incrementally coded measurement rings, Figure 2, page 2. The product designation YRTCMA or YRTSMA refers to the first design and YRTCMI to the second.
