It is used for infinite stroke and cylindrical shaft. Because the load ball is in point contact with the shaft, the use load is small. The steel ball rotates with very little frictional resistance, so that it can obtain high-accuracy and smooth movement Linear Bearing Features: Linear bearings are used in conjunction with hardened linear drive shafts. A system for infinite linear motion. The load ball and the hardened drive shaft are in point contact and allow a small load. Application: Widely used in electronic machinery, power tools, sports equipment, packaging machinery, food machinery, printing machinery, woodworking machinery, crystal machinery, textile machinery, light industry machinery, mining machinery, engraving machines and automation equipment, numerical control equipment, etc. Uses: Linear bearings are widely used in accuracy equipment such as electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment, as well as industrial machinery such as the sliding parts of machine tools, punches, tool grinders, automatic gas cutting machines, printers, card sorters, and food packaging machines1This is a linear motion system produced at low cost for infinite travel with cylindrical shafts 2Small load due to the contact between the load ball and the bearing point 3The steel ball rotates with very little frictional resistance, so that it can obtain high-accuracy and smooth movement 4The load ball and the hardened drive shaft are in point contact and allow a small load. However, when moving in a straight line, the frictional resistance is minimal, the accuracy is high, and the movement is fast. 5Widely used in electronic machinery, power tools, sports equipment, packaging machinery, food machinery, printing machinery, woodworking machinery, crystal machinery, textile machinery, light industry machinery, mining machinery, engraving machines and automation equipment, CNC equipment, etc. 1 x&nbspRound Flange Linear Motion Bearing
