Stiffness of the ball screw nut, in most cases, far less than the RZ rigidity ball screw nut ball screw stiffness Rmu, Rmu generally 3-5 times of RZ. In the design, complete general accounting Ball stiffness, will not need to be accounted for separately stiffness of the ball screw nut. Ball bearing are the following four ball screw use, due to the different way the support, so as to permit axial load and allowable rotation speed is also different ball screw factory, customers should be properly selected according to their own circumstances. 1. Fixed - fixed for high-speed, high-precision, high requirements for installation 2. Fixed - support for medium-speed, high precision, the most common support structure 3. The support - support for medium-speed, the accuracy. 4. Fixed - free for low speed, the precision, short axial screw ball screw all have what features it: 1, ensure high-precision ball screw is manufactured in Japan using the world's highest level of consistent production machinery and equipment out, especially it in assembly, grinding, inspection and other processes in the plant environment, while also being able to temperature and humidity are very strict control, but also have a sound quality management system, and thus allows accuracy to be fully guaranteed. 2, compared it with the sliding screw drive torque deputy 1/3 Ball brand, Lijiang Ball, Shandong Fu Jun is provided by Mechanical Technology Co., Ltd. Shandong Fu Jun. Machinery Co., Ltd. Shandong Fu Jun (www.fumotor.com) strong, credible, machinery and industrial products in cooperation projects in Shandong Weifang industry has accumulated a large number of loyal customers.
