uxcell LM8UU Linear Ball Bearings 8mm Bore 15mm OD 17mm Long for CNC Machine 3D Printer 10pcs

Linear motion bearings provide freedom of movement in a single direction.Often used in conjunction with cylindrical shaft or rail.The steel ball is in point contact with the shaft and rotates with very little frictional resistance, so as to obtain smooth movement with high precision.Linear Ball Bearing Motion Slide Units Grease may be applied prior to use to improve smoothness.Maintain lubrication of optical shafts and guides during operation.The recommended load is 80% of the rated load, exceeding the rated load will affect fluidity.The table needs to be level during installation, otherwise it will interfere with installation calibration.Require regular cleaning and maintenance.Applications Linear Motion Bearing X-Y tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
