Shanghai Ball price _ Ji 宁博特 Seiko (certified) _ Ball provided by Shandong Bot Seiko Corporation. Shandong Bot Seiko Co., Ltd. (www.jsinfo.com.cn) is specialized in the "ball screw, lead screw, linear guide, spindle," the enterprise, the company of "honesty, hard service" concept, for You provide the most quality products and services. Welcome to inquire! Contact: Zhang complete. Shandong Bot Seiko Co., Ltd. (Shandong Jining former screw factory) Tianjin Ball price, was founded in 1966, the national high-tech enterprise, the key features of the domestic industry of specialized production plant. For over 40 years, the company has been dedicated to the research and production of key features. Its production of ball screw features: high feed and micro-feed may ball screw ball movement, so very small starting torque Shanghai Ball supply, does not appear as a sliding movement creeping phenomenon, to ensure accurate micro feed. Shandong Bot precision ball screw Feature: 1, more provincial power sliding screw drive torque of only 1/3 of vice, with high movement efficiency, more power. 2, high-precision ball screw is made to ensure that a high level of consistent production out of machinery and equipment, higher production accuracy. 3, micro-feed may ball screw ball movement, so very small starting torque Ball Chongqing supply, does not appear as a sliding movement creeping phenomenon, to ensure accurate micro feed. 4, no backlash, high rigidity ball screw preload can be added, as a result of the pre-axial clearance can achieve negative pressure, and thus get a higher rigidity. 5, the high feed motion due to the high efficiency ball screw, heat, it is possible to achieve high feed 6, high reliability compared with other transmission machinery, hydraulic, ball screw drive system failure rate is very low, maintenance is also relatively simple, just for general lubrication and dust. Can operate without lubrication on special occasions. 7. Turn the ball high durability at contact were hardened (HRC58 ~ 63) treatment, and the precision grinding process is purely rotational cycle system, relatively little wear and tear, it has a higher life and maintain the accuracy of the .
