The azimuth bearing schemes in typical large Alt-azimuth telescopes  especially the 3.5-m APO telescope and the 4.1-m SOAR telescope were analyzed. A scheme of high-angular contacted thrust ball bearing integrated with a radial ball bearing was put forward. According to the Hertz contact theory  the corresponding parameters were designed for engineering application. The static performance parameters  within the range of 60 85 original contact angle were calculated. Compared with the traditional plane thrust ball bearing  the results shows that the high-angular (80) contact thrust ball bearing has more benefits at bearing strength and rigidity for large telescope. The 1500mm diameter prototyping bearing shows good performance  including the axial jitter is 0.009mm  the radial jitter is 0.006mm  the maximum starting torque without load is 30N·m  and the load capacity is more than 30t  which offers advanced technique path for the buildup of the high precision azimuth shafting and the whole telescope system. 2010 Copyright SPIE - The International Society for Optical Engineering.
