Linear bearings linear guide is a very important component, is a low-cost production of linear motion systems, Yan'an linear guide, for unlimited travel in conjunction with the cylinder axis. As was carrying the ball point contact with the shaft, so the use of small load. With minimal friction ball rotation, which can get high-precision smooth movement. Four-row linear guide using arc grooves, with four rows of steel ball contact angle of 45 degrees, the linear guide wholesale, allowing the ball to achieve the desired two-point contact structure can withstand the load from the vertical and horizontal direction; if necessary, more preload may be applied to increase the rigidity. Linear guide interchangeable because of the strict control of manufacturing precision, linear guides, linear guide size can be maintained at a certain level, and the slider has cage designed to prevent the ball off, and therefore part of the series of precision tools interoperable transsexual, customers need to order to follow the rail or slider, linear guide factory, rail and slider can be stored separately in order to reduce storage space. All have high rigidity in all directions using four-row circular arc grooves, with four rows of steel ball contact angle of 45 degrees, allowing the ball to achieve the desired two-point contact structure can withstand the load from the vertical and horizontal direction; if necessary, more preload may be applied to increase the rigidity.
