Four Row Taper Roller Bearing

THE Selecting linear slides and linear stages requires an analysis of axis configuration and travel specifications.Single-axis systems have only one carriage or saddle and move along the X-axis. By contrast, vertical lift devices move along the Z-axis. Some stacked or coupled units, referred to as multi-axis positioning systems, move along two--usually orthogonal--axes in the X-Y plane. Others include one carriage that moves along the X-axis and another carriage that moves along the Z-axis. Three-axis systems provide motion in three orthogonal axes. Important travel specifications for linear slides and linear stages include X-axis linear travel, Y-axis linear travel and Z-axis linear travel.
