滑动轴承（sliding bearing），轴与轴承间的相对运动为滑动的轴承，称之为滑动轴承。

滑动轴承由轴承座和轴瓦/轴套组成。

滑动轴承的材料有金属-高分子复合材料(MPC)、Teflon纤维等。

与滚动轴承相比，滑动轴承的

滑动轴承可以采用油润滑、脂润滑、水润滑等方式。

滑动轴承用润滑脂的选择：

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. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand. All linear slides provide linear motion based on bearings, whether they are ball bearings, dovetail bearings, linear roller bearings, magnetic or fluid bearings. XY Tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
