Double-Layer Ball Bearing Drawer Slides 12"-28"

HA5103 Double Layer Ball Bearing Drawer Slides 

Some drawer systems need to open beyond the front edge of a cabinet or machine frame, especially when the contents at the rear are difficult to reach. This slide uses a stacked arrangement to create additional outward travel without requiring a complicated external mechanism. Steel balls positioned between the moving sections help reduce friction and keep the motion even throughout the opening process.

Because the sections remain permanently assembled, the drawer cannot be removed simply by pulling it forward. This can be useful in equipment where the components need to stay securely connected during operation or transportation. The steel body also provides dependable support for frequent use.

It can be fitted to workshop storage, machinery housings, service carts, medical units, filing systems, and custom furniture. The design is suitable for projects where ordinary drawer runners do not provide enough reach and where convenient access, controlled movement, and a fixed connection are important.

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

Made from 1.5 mm thick cold rolled steel, with a surface finish that passes a 48 hour 5% salt spray test.

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

Testing Equipment
The double-stack design provides additional travel where instruments or testing platforms need to move farther out.

 

Deep Storage Cabinets
The over-extension design improves access to the full drawer space, especially in cabinets with greater installation depth. 

Machine Enclosures
The cold-rolled steel construction offers good structural support for pull-out components installed inside machinery.

 

Maintenance Cabinets
The extended travel makes stored parts and equipment easier to reach during inspection and repair work. 

Q: Is this slide suitable for frequent operation?
A: The ball bearing structure provides smooth movement for repeated use, although performance also depends on correct installation, loading, and working conditions.

Q: Does this slide require regular maintenance?
A: It is recommended to keep the slide clean, check the mounting screws periodically, and maintain proper lubrication for consistent movement.

Q: Can the slide be installed horizontally or flat?
A: Side mounting is recommended. Flat mounting can significantly reduce the load capacity and should be evaluated before use.
