Shaft Support Linear Ball Bearing refers to a type of bearing that provides support to the load of the carriage during its single-axis linear movement and provides a low friction sliding surface for the guide rails. Shaft Support Linear Ball Bearing is a critical component of the linear guide assembly. These applications are used in X-Y positioning tables, cutting machinery, machine slides, industrial robots, and instrumentation systems. These are used as a bearing pillow that bearing blocks allow shafts to rotate freely and support to prevent rotational and axial movement of the mounted shaft.
