Introduction
Linear bearings play a pivotal role in countless industrial applications, enabling smooth and precise linear motion. Their versatility, efficiency, and durability have made them indispensable in a wide range of industries, including precision manufacturing, robotics, semiconductor processing, and medical equipment.
Understanding Linear Bearings
Linear bearings, also known as linear guides or slide bearings, are used to support and guide moving elements along a straight path. Unlike ball or roller bearings that support rotating shafts, linear bearings provide guidance for linear motion. They consist of two main components: a bearing block and a rail. The bearing block houses ball or roller elements that roll along the rail, reducing friction and providing smooth movement.
