1. Features of linear motion rolling support:
(1) The linear motion rolling bearing is made of GCr15 bearing steel and consists of a hardened high-precision support base and rolling elements. It is installed on the machine guide rail and other mechanical surfaces for reciprocating linear motion. It is suitable for grinding machines, precision instruments, and also for CNC machine tools and heavy-duty machine tools.
(2) The support has the advantages of large carrying capacity, low friction, small wear, good rigidity, long service life, and high precision for a long time. In the case of repeated action, start and stop reciprocating motion, the weight of the whole machine and the transmission mechanism and power consumption can be reduced.
(3) The rolling bodies of the support are guided well when rolling, so that the motion precision and the positioning accuracy of the machine can be improved.
(4) The bearing has good control performance when performing low-speed reciprocating or fine adjustment, and the movement is light and does not cause creep.
(5) When the bearing is used, it is not limited by the machine bed. The number of rolling bearings can be selected and determined according to the load values specified by the different series and different types of bearings in the sample.
(6) After the support, the positioning accuracy of the machine tool is high, the equipment assembly adjustment is convenient, the lubrication is easy, the maintenance is simple, and the use is safer and more reliable.
