HIIWN linear motion guide has the advantages of simple structure, easy manufacturing, contact stiffness, etc. But the traditional guide friction resistance, wear fast, dynamic and static friction factor difference is large, easy to produce crawling phenomenon at low speed. HIIWN linear motion guide friction coefficient is small, good smoothness of movement can prevent the low-speed crawling phenomenon, and good wear resistance, self-lubricating effect, and vibration resistance. Then how should HIIWN linear motion guide have installed? The next is some introduction.

Preparation before installation
Before installation, the corresponding mechanical scratches, burrs, and stains are cleaned out, to know that in the HIIWN linear motion guide on the anti-rust oil, when in the installation before, we have to clean him first, and then in the installation. If this anti-rust oil is not there, it is very easy to rust, you can choose a relatively low viscosity lubricant.
Installation of rail base seat
Install the fixed HIIWN linear motion guide rail channel base on the floor of the bottom pit. Its center should coincide with the centerline of the car rail. After leveling the base seat of channel steel, and M16 expansion bolt is played at each edge of both ends of the channel steel to connect the channel steel with the floor of the pit to fix it, and the pit can be welded with the steel if there is structural steel. The level error of the base of the channel steel is not more than 1/1000. after the position of the base of the channel steel is determined, it is filled with concrete and smoothed around. The angle steel frame used to fix the HIIWN linear motion guide rail at both ends of the channel steel base seat is fixed after the centerline of the car guide rail is corrected first. If there is no channel steel base seat under the HIIWN linear motion guide, a steel plate with a thickness ≥of 12 mm and an area of 200 mm×200 mm can be padded under the guide, and spot welded with the HIIWN linear motion guide by electric welding. The ground of the bottom pit should not be higher than the upper plane of the base seat of the channel steel. The use of oil lubrication of the guide rail, the need to establish the foundation of the guide rail before the lower end of the 40 mm high from the ground level of a section of the work surface sawed off to leave the location of the oil box. Or in the HIIWN linear motion guide under the oil groove, oil flow directly into the oil box placed on the side.
Rail installation
Hang a pulley at the center hole of the top floor and fix it firmly for lifting the HIIWN linear motion guide. Floor higher than 12 floors and above can be considered to use winch lifting rail, lower than 12 floors can use nylon rope (or steel wire rope) human lifting, nylon rope (or steel wire rope) diameter should be greater than 25 mm, lifting HIIWN linear motion guide to use double hooks hooked rail connection plate. The convex tenon head of the HIIWN linear motion guide should face upward, and the dust on the tenon should be cleared to ensure that the gap at the joint meets the specification requirements. Install the rail at the same time to install the pressure plate and fill 1 ~ 2 mm spacers between the rail and the bracket, the top of the last rail and the floor spacing is not more than 100 mm. long excess HIIWN linear motion guide should be sawed off using a grinding wheel, the use of gas welding cutting is strictly prohibited.
Adjust the rail
Remove the installation line of the HIIWN linear motion guide rail bracket, put the centerline of the car guide rail at the location of the centerline of the car guide rail determined on the sample board, and fix it. Use a steel blind ruler to check the distance between the end surface of the guide rail and the centerline of the car guide rail, and adjust the method of adding or subtracting shims between the guide rail bracket and the guide rail to make the distance between the end surface of the guide rail and the centerline of the car guide rail consistent at each measuring point.
