4Pcs of LM25UUOP 25mm Bore 40mm OD 59mm Len Linear Bearing Open Type for CNC Description: Linear ball bearing motion system: Linear bearings are linear motion systems for linear travel in conjunction with cylindrical shafts. Since the load bearing balls are in point contact with the bearing jacket, the balls roll with minimum frictional resistance, so linear bearings have low friction and are relatively stable, do not vary with bearing speed, and can obtain smooth linear motion with high sensitivity and high precision. .
