Linear-motion bearing. A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings. Motorized linear slides such as machine slides, XY tables, roller tables and some dovetail slides are bearings moved by drive mechanisms.
Basal sliding. Glaciers can slide because ice melts under pressure, resulting in a film of water at the ice-bed interface. This can facilitate decoupling and enhance fast ice flow. If the glacier bed is rough, with many bumps and obstacles, this increases melting and ice flow. This process is known as regelation.laciers always flow downslope, through the processes of deformation and sliding. Glacier flow, velocity and motion is controlled several factors (Jiskoot et al., 2011), including those listed below: 1  Ice geometry (thickness, steepness),
