What is the difference between ball-bearing and roller drawer slides?

The main difference between ball-bearing drawer slides and roller drawer slides lies in how they create their sliding motion and how load-bearing they are.

Ball-bearing slides use a series of small balls in a cage, allowing the drawer to glide smoothly and quietly. This type of slide is usually more expensive because it is more complex to manufacture. However, it is also more powerful and load-bearing, so it can support heavier loads. Ball-bearing slides are also available as full-extension or over-extension slides, meaning you can access the entire contents of the drawer.

Roller drawer slides use small wheels or rollers to enable the sliding motion. This type of slide is usually cheaper and easier to install. However, they are not as load-bearing as ball-bearing slides and are therefore generally only suitable for lighter applications. They usually allow only partial extension, meaning part of the drawer remains hidden inside the cabinet.

• So: If you are looking for an economical solution and your drawers will not be loaded too heavily, roller drawer slides could be the best choice.
• On the other hand, if you are looking for a durable, heavy-duty solution and are willing to spend a little more, you should consider ball-bearing slides.
