A rolling guide unit is disclosed of the curved movement type that together with achieving increased load capacity and rigidity, improved vibration damping characteristics, low noise levels, smooth operation and an extended service life, also demonstrates adequate functions particularly with respect to generated centrifugal force. The above-mentioned effects are obtained by employing a cross roller system in particular.
