Description
HA5103 Double Layer Ball Bearing Drawer Slides
This slide rail is designed for drawer systems that need more travel distance than a regular slide can provide. Its over travel structure allows the drawer to extend further forward, making access more convenient in daily use. The cold rolled steel construction gives the slide a steady base for repeated opening and closing, while the ball bearing movement helps reduce friction during operation. Available in 12'' to 28'' lengths, it can be selected according to different drawer depths and project requirements.

Allows the drawer to extend beyond the standard range for better accessibility.

Made of 1.5 mm cold rolled steel, with the surface tested in a 5% salt spray solution for 48 hours.

The ball bearing action can create a quiet environment at work.

Nylon buffer can reduce the direct contact between the outer and the inner channel.

APPLICATIONS

Industrial Drawer
Provides longer pull-out distance, making it easier to reach items stored at the back of the drawer.

Tool Cabinet
Helps users access tools more clearly and conveniently, especially when the drawer is deep.

Pull-Out Tray
The over travel design gives the tray more extension space, making inspection or operation easier.

Equipment Storage Drawer
Helps improve access to stored components while keeping the drawer movement steady.
Q: What does "over travel" mean for this slide?
Over travel means that the slide can extend beyond its original closed length, providing a longer pull-out distance than a standard full-extension slide. This design allows better access to the contents or equipment inside, especially when the installation requires additional travel and the rear area needs to be reached more easily.
Q: Can the HA3504 help improve access to the back of the drawer?
Yes. Its over travel design allows the drawer to extend further forward, so users can reach the back area more easily without removing the drawer or changing the cabinet structure.
Q: Is the double stack structure different from a regular three section slide?
Yes. Unlike a regular three-section slide, the double stack structure is specifically designed to provide additional travel distance. It allows the drawer or moving component to extend farther while using a similar amount of installation space, making it suitable for projects where standard full extension does not provide enough access.
