With the widespread use of high-precision linear guides in industrial automation, it is necessary to master certain installation techniques. Mastering the correct method of installing linear guides can improve the service life and accuracy of the guides.

To ensure parallelism between the driven side slide rail and the reference side slide rail during installation without lateral positioning of the assembly surface.

1、 Installation method using installation reference plane

Firstly, use assembly screws to roughly fix the bottom reference plane of the linear guide rail to the assembly surface at the bottom of the bed. Then, use a vise to press the reference plane on the side of the slide rail against the assembly surface at the bottom of the bed to determine the position of the slide rail. Then, use a torque wrench to tighten the fixing screws in sequence with a certain amount of torque, and press the reference plane at the bottom of the slide rail against the assembly surface at the bottom of the bed.

2、 Installation of linear guide rail on the driven side

1. Linear block gauge method

Place the linear block gauge between two linear guide rails, use a micrometer to calibrate the linear block gauge so that it is parallel to the side reference plane of the reference side slide rail, and then calibrate the driven side slide rail according to the linear block gauge. Start calibrating one end of the driven rail and lock the assembly screws with a specific torque in sequence.

2. Mobile Platform Method

Fix the two sliding blocks on the reference side on a measuring platform, while only one sliding block is installed on the driven side. The slide rail and sliding block have not been fixed on the bed and platform yet. Use a micrometer attached to the top surface of the driven side sliding block to measure the side reference plane of the driven side sliding block. Start calibration at one end of the driven linear guide rail and lock the assembly screws with specific torque in sequence.

3. Following the benchmark side sliding rail method

Fix the two sliders of the reference side linear guide rail and one of the sliders of the driven side guide rail to the platform, and then roughly fix the slide rail of the driven side and the other slide rail to the bed and platform respectively. Move the platform based on the reference side slide rail. Starting from one end of the slide rail, confirm the rolling resistance of the driven side linear guide rail while locking the assembly screws with specific torque in sequence.

4. Special tool method

Use professional tools to determine the position of the driven side slide rail and lock the assembly screws with specific torque in sequence.
