Six steps for linear bearing installation

Everyone should know that there are many applications of linear bearings in machinery. In all kinds of machine equipment, linear bearings can achieve maximum performance and achieve the maximum economic benefits of automation and labor saving. The characteristics of linear bearings are lightweight, corrosion resistance, interchangeability, and low cost. However, many people do not know what preparations should be made before installing linear bearings. What should be paid attention to during installation and use? Below, Xiaosu will share with you the six major installation steps of linear bearings.

1. Before installing the linear bearing, the burrs, dirt and surface scratches on the mechanical mounting surface must be removed. The linear bearing is coated with anti-rust oil. Before installation, please wash the reference surface with cleaning oil and then install it. Usually, the reference surface is easy to rust after removing the anti-rust oil. It is recommended to apply the lubricating oil to the spindle with low viscosity.

2. Place the linear bearing gently on the bed, and use the side fixing screws or other fixing fixtures to make the wire rail and the side mounting surface lightly fit. Before installation, make sure that the screw holes are in agreement. If the base machining holes are not matched and the bolts are forcibly locked, the combination accuracy and quality of use will be greatly affected.

3. Screw the positioning screws of the linear bearing from the center to the sides in order, so that the rail fits the vertical mounting surface, and the tension from the center position to the both ends can obtain a more stable precision. When the vertical reference surface is slightly tightened, the locking force of the lateral reference surface is strengthened, so that the linear bearing can be surely fitted to the lateral reference surface.

4. Use a torque wrench to tighten the positioning screws of the linear bearing slides slowly according to the various materials.

5. Install the sub-rails using the same installation method, and install the slides to the main rails and sub-rails individually. Note that after the slider is installed with the linear slide rail, many subsequent accessories cannot be installed due to limited installation space, and the required accessories must be installed at this stage.

6. Gently place the moving platform on the slide of the main rail and the secondary rail of the linear bearing, and then lock the lateral tensioning screws on the moving platform.
