Drawer slide rail structure diagram - how to install drawer rail diagram

When it comes to installing drawer tracks, it's important to know the different components involved and their proper alignment. This article will provide a detailed guide on how to install the outer, middle, and inner rails of a three-slide rail drawer cabinet. Additionally, we'll cover how to adjust the tightness of the drawer slide rail and provide information on different types of slide rails available in the market.

Step 1: Understanding the Drawer Track Structure

Before we get started with the installation process, let's familiarize ourselves with the structure of a three-slide rail drawer cabinet. The sliding track consists of an outer rail, middle rail, and inner rail.

Step 2: Removing the Inner Guide Rail

To begin the installation, remove the inner guide rail from the edge of the drawer. You'll notice a spring at the back of the rail. Press lightly on both sides to remove the inner guide rail. Remember, the outer rail and middle rail are connected and cannot be separated.

Step 3: Installing Outer and Middle Rails

First, install the outer and middle rails on both sides of the drawer box. Then, fix the inner inverted frame on the side of the drawer. It's important to ensure correct alignment between the outer and inner rails to ensure the back of the drawer fits properly. If your furniture already has pre-drilled holes in the drawer cabinet and side, you can install the rails directly without the need for additional drilling.

Step 4: Assembling the Drawer

Before installing the slide rails, assemble the drawer as a whole. Look for two holes on the guide rail, which allow you to adjust the drawer's position up and down as well as front and back.

Step 5: Installing Inner and Outer Rails

Now it's time to install the inner and outer rails. The positions of the inner and outer rails should align. Secure the inner rail to the drawer cabinet using screws. Then, tighten the remaining screws that have not been locked yet.

Step 6: Repeat the Process on the Other Side

Using the same method, install the drawer tracks on the other side. Ensure the inner rails on both sides remain horizontal for proper alignment.

Step 7: Testing and Adjusting

After completing the installation, pull out the drawers to check if they function properly. If any issues arise, readjust the rails accordingly.

Adjusting the Tightness of the Drawer Slide Rail

If you need to adjust the tightness of the drawer slide rail, follow these steps:

Step 1: Remove the Slide Rail

First, take out the slide rail from the drawer and place it as shown in the diagram below.

Step 2: Check the Movement

Examine the movable track of the slide rail to ensure it moves smoothly without any obstructions.

Step 3: Locate the Fixed Rail Position

Find the position of the fixed rail, which needs to be installed on the cabinet.

Step 4: Install the Fixed and Inner Rails

Pull out the inner rail of the slide rail and install the fixed rail inside the cabinet. Then, install the inner rail on the drawer and adjust the tightness by changing the hole position.

Step 5: Reassemble the Drawer

After installation, reinsert the drawer into the fixed rail to complete the adjustment.

Different Types of Drawer Slide Rails

1. Roller Type

The roller type is the first generation of silent drawer slide rails. Though it's been gradually replaced by steel ball slide rails, it's still used in computer keyboard drawers and light drawers due to its daily push and pull capabilities. However, it lacks in bearing capacity, buffering, and rebound functions.

2. Steel Ball Type

Steel ball slide rails are commonly used in modern furniture. They consist of two or three-section metal rails installed on the side of the drawer. They provide smooth sliding, high load-bearing capacity, and often feature buffer closing and rebound opening functions.

3. Gear Type

Gear slide rails are medium to high-end options, known for their smooth and synchronous movement. They include hidden slide rails and horse-riding slide rails. Though relatively expensive, these slide rails offer cushioning and closing or pressing rebound functionalities.

4. Damping Slide Rail

Damping slide rails utilize the buffering performance of liquids to provide a sound-absorbing and buffering effect. They are known for their soft and silent closing, making them an ideal choice for high-grade furniture. The hydraulic buffer technology they employ ensures a comfortable closing effect and saves maintenance effort.

Installing drawer tracks might seem like a daunting task, but with a clear understanding of the process, it can be a straightforward endeavor. By following the step-by-step guide provided in this article, you'll be able to install and adjust the drawer slide rails with ease. Remember to choose a slide rail type that best suits your furniture and functional requirements.
