Linear Bearings are widely used in the CNC industry to achieve high-precision, high-speed, and highly reliable motion control. Linear bearing also called linear bearing blocks, linear guide blocks, and guide rail carriage,  is used for machine tool motion control. For example, in three-axis machining centers, they are used for the linear movements of the X, Y, and Z axes to ensure machining accuracy, such as CNC woodworking router machines, CNC woodworking lathes, and metalworking machine tools. Linear guide sliders are also used for the linear motion of robotic arms to improve positioning accuracy. Additionally, they are employed in other machine tools such as lathes, grinding machines, laser cutting machines, 3D printers, etc.

Considering the wide application, we’ll talk about what’s the linear bearing carriage feature, and why plenty of industries use it. 

Feature 1: Low Friction and High Working Effenicy

The driving force is reduced because linear guides have low friction. Only a small power is needed to move the machine, it reduces the heat generated by friction and makes them more suitable for high-speed movement.

Feature 2: High Accuracy Linear Bearing Blocks

The working accuracy of the linear bearing block is high. The movement of the linear guide is achieved through the rolling balls inside the block. This reduces the coefficient of friction. As a result, therefore stable motion is achieved, reducing shocks and vibrations, and enabling precise positioning. This is beneficial for improving the response speed and sensitivity of the CNC system.

Feature 3: Simple Lubrication Structure of the Linear Bearing Block

The lubrication structure of the linear bearing block is simple. The linear guide block has a lubrication hole, which allows for lubrication oil can be poured into the block inside. This point can keep the machine minimize wear and maintain high precision for a long period.

Feature 4. Interchangeable Linear Bearing Block

The linear bearing block is easy to install and has highly interchangeable features. The linear bearing block has high straightness, and the screw holes in the linear bearing block have minimal errors. This allows the machine to achieve high precision again after reassembly.

Feature 5. Strong Sealing Capabilities of Linear Bearing Block

The linear guide has strong sealing capabilities and good dustproof performance. Most sliders are equipped with sealing end caps at both ends to ensure tight sealing. A dustproof bottom plate can be optionally installed at the bottom. The screw holes for fixing the guide are also equipped with dust covers to prevent dust accumulation, therefore maintaining the product's performance and service life.
