1.Linear motion rolling bearing characteristics:
(1)The linear motion rolling bearing using GCr15 bearing steel, hardened high-precision bearing substrate and the rolling body composition. Installed on the surface of the rail of machine tool and other machinery for reciprocating linear motion, applicable to the grinding machine, precision instruments, and also applies to CNC machine tools and heavy machine tools.
(2)The bearing has the capacity to carry large, small friction, wear small, good rigidity, long life, long-term to maintain the advantages of high accuracy. Repeated action, start, stop, reduce the machine weight and transmission, as well as power consumption, higher frequency of reciprocating motion.
(3)The orientation of the bearing rolling element rolling, which can improve the accuracy and positioning accuracy of mechanical movement.
(4)The bearing during the low-speed reciprocating motion or fine-tuning control performance, lightweight mobile, no crawling.
(5)Not subject to the limitations of the machine bed, using the bearing can be selected in accordance with the provisions of the samples of different series and different model specifications bearing load value and determine the number of use of rolling bearings.
(6)The supporting machine tool positioning reference accuracy, easy adjustment of equipment assembly, lubrication easy and simple maintenance, use more secure.
