Plastic linear bearings are self-lubricating properties of a linear motion system, the biggest difference is the metal of the metal linear bearings linear bearings are rolling friction ball screw quote, is a small point of contact between ball screw bearings and cylindrical shaft, so this species suitable for low load speed movement; and plastics processing sliding friction linear bearings are ball screw is between the bearing surface contact with the cylinder axis, so this suited for high load low-speed movement. Two types of linear bearings described above is relatively common in industry is relatively common linear bearings, especially the most common in the automotive parts, machinery accessories. Feng Cheng Bearing Co., Ltd. We specialize in auto parts, bearings and other products, excellent quality ball screw, full-service, give you the most satisfying shopping experience. Proper use of linear guides. Selection Required linear guide according to the conditions, load capacity, and life expectancy choose. The so-called conditions of use which mainly refers to the application equipment, precision, rigidity requirements, load mode, stroke, speed, frequency of use, the environment and other factors. According to the conditions of the right to select the corresponding product family. Linear guide the selection process can be a specific reference to the following sequence usually. Can improve the pre-pressure, selection process can be returned at any time according to the previous method of calculation to re-select and set. When calculating the slider to confirm the selection of the maximum load linear guide static safety factor should exceed the value listed in the guide. Insufficient if the chosen vice rigid linear guide. Increase the choice of size or increase the number of sliders to increase rigidity. Static safety factor is defined as the static load rating and workload ratio.
